Abstract This work is a brief analysis on the application and perspective of using the walking robots in different areas in practice. The most common characteristics of walking four legs robots are presented here. The specific features of the applied actuators in walking mechanisms are also shown in the article. The experience of Institute of Mechanics - BAS is illustrated in creation of Spiroid and Helicon1 gears and their assembly in actuation of studied robots. Loading on joints reductors of robot legs is modelled, when the geometrical and the walking parameters of the studied robot are preliminary defined. The obtained results are purposed for designing the control of the loading of reductor type Helicon in the legs of the robot, when it is experimentally tested.

Cet article s'inscrit dans un travail mené, à partir d'une enquête dans une entreprise française de petit électroménager, sur les relations entre l'innovation industrielle et le monde domestique. Au cours de l'enquête, nous avons suivi en temps réel le processus de conception et de mise en fabrication de robots de cuisine multifonctions. Deux aspects du travail d'innovation sont analysés ici. Dans une première partie, nous montrons comment les innovateurs conçoivent les robots pour l'usage, comment, au cours de ce travail, ils prennent en considération les usagers et usagères des appareils et comment ils en construisent des représentations hétérogènes. À la conception des appareils est liée celle des actions des femmes lorsqu'elles les utilisent, et donc se pose la question des modes de prescription de l'usage que les innovateurs inscrivent dans les objets. Une deuxième partie traite de la conception des produits pour l'appareil de production ainsi que de la modification des postes de travail, des outillages et des modes opératoires des ouvrières pour la fabrication d'une nouvelle gamme de robots. D'autres formes de prescription de l'activité des femmes sont aussi mises en œuvre par les innovateurs; nous tentons d'analyser ce qu'en font les opératrices.

This paper presents a design methodology for parallel robots having to satisfy a set of performance constraints. Some of these constraints are used to compute a closed region in the parameters space (in which a point define an unique robot geometry) which define all the robot geometries fulfilling these constraints. Then a grid is created over this region and for each node of this grid the requirements, expressed in a high level language, are evaluated. The node leading to the robot best fulfilling the constraints is the design solution.

In this paper, a model of an orthotic robot’s lower limb rotation system is presented. The system is intended for use in typical contemporary orthotic robots such as the ‘Veni-Prometheus’ System for Verticalization and Aiding Motion designed at the Faculty of Mechatronics, Warsaw University of Technology. In the paper, the state of the art is briefly stated, with the relatively low number of orthotic robots allowing realization of pivoting turns highlighted. The intended two-stage pivoting turning movement is analyzed in detail and the operating conditions as well as limitations of the turning module are indicated. The conception of a turning module introduces additional degree of freedom to the existing orthotic robot designs by realizing the rotation about the lengthwise axis in the thigh link. A three-dimensional model and its analysis are shown. The proposed design ensures the necessary movement of the lower limb and the torso of an impaired person during the execution of pivoting turn while remaining compact in order to ease the introduction of the turning system to different orthotic robot designs.

This paper presents a new conception and analyzes a hyperredundant continuous robot (continuous style manipulator), drive system, and control strategy. The robot includes ten flexible segments and can be extended to several components as needed. The chosen hyper-redundant robot has a continuous infinite hybrid structure (HHRIC), based on hydraulic control with a rheological element. This system combines the advantage of a joint-level drive with a lightweight construction similar to the base-driven robots. It is suitable for tasks such as wiring in hard-toreach areas (caves, subaccounts, steep areas), transportation of fluids or food to areas affected by natural disasters (people buried under ruins), exploration in difficult areas (speleological research). Generally, the control algorithms for hyper-redundant robots are specific to the robots’ constructive particularities to which they have applied and the environment in which they operate. Experimental results validate the proposal robot design and control strategies in virtual reality. As a result, it is concluded that hyper-redundant robots and immersive technologies should play an essential role soon in automated and teleoperation applications.

SUMMARYIn this paper, we present a novel structure of a snake-like robot. This structure enables passive locomotion in snake-like robots. Dynamic equations are obtained for motion in a horizontal plane, using Gibbs–Appell method. Kinematic model of the robot include numerous nonholonomic constraints, which can be omitted at the beginning by choosing proper coordinates to describe the model in Gibbs–Appell framework. In such a case, dynamic equations will be significantly simplified, resulting in considerable reduction of simulation time. Simulation results show that, by proper selection of initial conditions, joint angles operate in a limit cycle and robot can locomote steadily on a passive trajectory. It can be seen that the passive trajectory is approximately a Serpenoid curve.

The authors attempt to model a decision-making mechanism; which can fix multiple robot characteristics and can aid in investigating robots status for a particular manufacturing arena. The work exposed a series of applicable robot characteristics; which differentiated their working capacity and defines their value. A simple additive weighting (SAW) mechanism under a fuzzy concept is presented for investigating the status of industrial robots; which incorporates comprehensive aspects for sustainable robot selection. The authors have extended the application field of fuzzy sets theory and illustrated the significant application of linguistic terms in the robot decision-making problem. The work compounds fuzzy sets theory with SAW techniques and thus serves a flavor of fuzzy concept and a SAW technique under single platform. The study reveals the course of action for executing the proposed work by the managers. The work has applied fuzzy linguistic terms for griping the appropriate perceptions of the decision makers and applied the conception of SAW methodology to yield the decision results.

Goudey and Bonnin provide an important demonstration of our willingness to accept robots regardless of the degree to which they look like us. This comment seeks to expand their insights in two ways. First, by broadening our conception of what constitutes a robot, I argue that we have already accepted many non-humanoid robots, and that even robotic entities without a visual presence can be compelling and engaging. Second, I suggest expanding the original paper’s psychological treatment of category ambiguity through the anthropological treatment of Mary Douglas. Douglas suggests that category ambiguity is abhorrent because things perceived to transgress categorical boundaries challenge our cultural beliefs and social order. In the case of robots, the beliefs that are challenged are our basic understandings of what makes humans unique and privileged in the world. As machines grow more and more capable, by some accounts they threaten to eclipse and even supplant the human race. I identify several behavioral and ethical research issues that are imperative if we are to deal with and prepare for such possibilities.

Sex robots, in a broad ethical sense, challenge our traditional social norms, sexual interactions, and how we visualise the human body. As a distinct sex stimulation technology, sex robots are ethically problematic because of the humanlike characteristics that these technologies embody. In this paper, I argue, on the one hand, that the design of sex robots objectifies the human body, from an African perspective, because of their humanoid appearance. This objectification of the human body contradicts the African conception of the human body as possessing inalienable dignity, vitality, and sacredness. On the other hand, I show how the designs of sex robots reinforce adverse stereotypical gender norms and standards of beauty. This paper is significant because it deploys sub-Saharan African values of sex and the human body to make a novel contribution to the ethical discourse of sex robots.

Cet article propose un ensemble de stratégies visant à développer la créativité des élèves dans le domaine de la conception technique en activités créatrices et manuelles (ACM). Plusieurs disciplines sont convoquées afin de provoquer une démarche interdisciplinaire intégrant le français, le design d'objets (robots) et la programmation informatique. Le modèle théorique de John Didier et Denis Leuba resituant l'objet produit dans un processus de socialisation, permet d'intégrer l'objet technique dans un cadre plus large, en l'occurrence ses multiples usages sociaux possibles. Dans l'expérimentation analysée, le robot devient un élément d'un processus de communication aboutissant dans la réalisation d'une pièce de théâtre. L'objet technique n'est plus ainsi réduit à un artefact matériel, mais il devient instrument de communication de sens, en d'autres termes, il devient en quelque sorte un média.

To produce multi-modal mobility in complicated situations is a significant issue for soft robots. In this study, we show the conception, construction, and operation of an inchworm-impersonating dielectric elastomer-activated soft robot. The robot is small and lightweight, weighing only 3.5 g, and measuring an overall 110 mm by 50 mm by 60 mm (length, width, and height). The three mobility modes for the robot are each equipped with a detailed mechanism. When the excitation voltage is 5 kV, the robot runs forward under a frequency of stimulation of 1–9 Hz, and its direction of motion changes to a backwards motion at >10 Hz. When the excitation voltage of 5.5 kV is applied to the robot, the robot runs forward at 1–12 Hz frequency and moves in the opposite direction at 13 Hz, reaching the fastest reverse speed of 240 mm/s. When the excitation voltage rises to 6 kV, the robot reaches its fastest running speed of 270 mm/s at 14 Hz. Motivated by high voltage and high duty cycle, the robot can jump over obstacles of 5 mm. In order to assess the performance of backward running, the speed achieved by the robot under a 30% duty cycle and a 50% duty cycle was compared, as well as the speed of the robot with or without the use of a counterweight. The robot has a simpler design and construction than earlier soft robots of the same kind, as well as a quicker speed, a wider variety of movement modes, and other notable advantages.

The legal conception and interpretation of the subject of law have long been challenged by different theoretical backgrounds: from the feminist critiques of the patriarchal nature of law and its subjects to the Marxist critiques of its capitalist ideological nature and the anti-racist critiques of its colonial nature. These perspectives are, in turn, challenged by anarchist, queer, and crip conceptions that, while compelling a critical return to the subject, the structure and the law also serve as an inspiration for arguments that deplete the structures and render them hostages of the sovereignty of the subject’ self-fiction. Identity Wars (a possible epithet for this political and epistemological battle to establish meaning through which power is exercised) have, for their part, been challenged by a renewed axiological consensus, here introduced by posthuman critical theory: species hierarchy and anthropocentric exceptionalism. As concepts and matter, questioning human exceptionalism has created new legal issues: from ecosexual weddings with the sea, the sun, or a horse; to human rights of animals; to granting legal personhood to nature; to human rights of machines, inter alia the right to (or not to) consent. Part of a wider movement on legal theory, which extends the notion of legal subjectivity to non-human agents, the subject is increasingly in trouble. From Science Fiction to hyperrealist materialism, this paper intends to signal some of the normative problems introduced, firstly, by the sovereignty of the subject’s self-fiction; and, secondly, by the anthropomorphization of high-tech robotics.

Abstract The development of artificial agents for social interaction pushes to enrich robots with social skills and knowledge about (local) social norms. One possibility is to distinguish the expressive and the functional orders during a human-robot interaction. The overarching aim of this work is to set a framework to make the artificial agent socially-competent beyond dyadic interaction – interaction in varying multi-party social situations – and beyond individual-based user personalization, thereby enlarging the current conception of “culturally-adaptive”. The core idea is to provide the artificial agent with the capability to handle different kinds of interactional disruptions, and associated recovery strategies, in microsociology. The result is obtained by classifying functional and social disruptions, and by investigating the requirements a robot’s architecture should satisfy to exploit such knowledge. The paper also highlights how this level of competence is achieved by focusing on just three dimensions: (i) social capability, (ii) relational role, and (iii) proximity, leaving aside the further complexity of full-fledged human-human interactions. Without going into technical aspects, End-to-end Data-driven Architectures and Modular Architectures are discussed to evaluate the degree to which they can exploit this new set of social and cultural knowledge. Finally, a list of general requirements for such agents is proposed.

This paper presents the virtual environment implementation for simulation and design conception of supervision and control systems for mobile robots, that are capable to operate and adapt in different environments and conditions. The purpose of this virtual system is to facilitate the development of embedded architecture systems, emphasizing the implementation of tools that allow the simulation of the kinematic conditions, dynamic and control, with monitoring in real time of all important system points. For this, an open control architecture is proposed, integrating the two main techniques of robotic control implementation in the hardware level: systems microprocessors and reconfigurable hardware devices. The implemented simulator system is composed of a trajectory generating module, a kinematic and dynamic simulator module, and an analysis module of results and errors. All the kinematic and dynamic results obtained during the simulation can be evaluated and visualized in graphs and table formats in the results analysis module, allowing the improvement of the system, minimizing the errors with the necessary adjustments and optimization. For controller implementation in the embedded system, it uses the rapid prototyping which is the technology that allows in set, with the virtual simulation environment, the development of a controller project for mobile robots. The validation and tests had been accomplished with nonholonomic mobile robot models with differential transmission.

This article presents the conception, the numerical modeling, and the control of a dexterous, deformable manipulator bio-inspired by the skeletal spine found in vertebrate animals. Through the implementation of this new manipulator, we show a methodology based on numerical models and simulations, that goes from design to control of continuum and soft robots. The manipulator is modeled using a finite element method (FEM), using a set of beam elements that reproduce the lattice structure of the robot. The model is computed and inverted in real-time using optimization methods. A closed-loop control strategy is implemented to account for the disparities between the model and the robot. This control strategy allows for accurate positioning, not only of the tip of the manipulator, but also the positioning of selected middle points along its backbone. In a scenario where the robot is piloted by a human operator, the command of the robot is enhanced by a haptic loop that renders the boundaries of its task space as well as the contact with its environment. The experimental validation of the model and control strategies is also presented in the form of an inspection task use case.

In the paper an approach to design and control of reconfigurable walking robots is presented. Based on the biological inspiration the conception of the six-legged robot is proposed. In the first part a mechanical structure, basic kinematical and dynamical dependences in the robot legs are described. The structure, kinetics rules, gait patterns etc. are derived from typical stick insects. According to the above assumptions the body and the legs of the robot are designed and made. At all legs eighteen DC servomotors with resistant encoders are used. In addition at the robot head one DC servomotor for sensors or a vision system is introduced. In the second part a control system is discussed. The multi-level control unit is based on the AVR Atmega8/16 microcontrollers which are responsible for generating of a movement trajectory and at the same time for controlling of the all servomotors. For the proposed control system different gait algorithms and behaviour rules including a forward/back movement, avoiding of obstacles are worked out. They allow an autonomous work of the robot or remote control by an operator. In addition, during the walk the algorithms can match the type of attitudes and gaits to an environment. Next, some experiments of walking for different control algorithms are carried out and described. At the end some conclusions and directions of the further research are given.

AbstractFor human ethics, it can convincingly be argued that justice is a central cornerstone and basis. Here, it is suggested that this can, to some extent, similarly be applied to robots. The article makes the argument that Rawls’ veil of ignorance in his conception of justice as fairness can effectively be replaced by a much more natural condition of prudent egoism in a finite world. Observing ones’ own important interests in an encompassing context paves the way for a guideline for the conduct, which is binding for humans, robots and each and every pragmatic agent with a minimum level of rationality. These arguments do not see humans (forever) in any privileged position: any agent, single human, state, alien or artificial with a certain minimum of general cognitive (and effective) capabilities is bound by a universal negative imperative. This entails that precautious procedures are preferable, and some general prudently constrained flexibility is required for self-consistency and survival.

Recent tendencies – such as the life-cycles of products are shorter while consumers require more complex and more unique final products – poses many challenges to the production. The industrial sector is going through a paradigm shift. The traditional centrally controlled production processes will be replaced by decentralized control, which is built on the self-regulating ability of intelligent machines, products and workpieces that communicate with each other continuously. This new paradigm known as Industry 4.0. This conception is the introduction of digital network-linked intelligent systems, in which machines and products will communicate to one another in order to establish smart factories in which self-regulating production will be established.
In this article, at first the essence, main goals and basic elements of Industry 4.0 conception is described. After it the autonomous systems are introduced which are based on multi agent systems. These systems include the collaborating robots via artificial intelligence which is an essential element of Industry 4.0.

Hydrodynamic coefficients are essential for the development of underwater robots; in particular, for their design and navigation control. To obtain these coefficients, several techniques exist. These methods are usually experimental, but, more recently, some have been designed by a combination of experiments with computational methods based on Computational Fluid Dynamics (CFD). One method for obtaining the hydrodynamic coefficients of an ROV (Remote Operated Vehicle) is by using an experimental PMM (Planar Motion Mechanism) or CWC (Circular Water Channel); however, the use of these experimental infrastructures is costly. Therefore, it is of interest to obtain these coefficients in other ways, for example, by the use of simple experiments. The Free Decay Test is an ideal type of experiment, as it has a low cost and is simple to implement. In this paper, two different free decay tests were carried out, to which three different methods for obtaining coefficients were applied. They were compared with results obtained by CFD simulation to conduct a statistical analysis in order to determine their behaviours. It was possible to obtain values of the drag and added mass coefficients for the models analysed, where the values were obtained for an Underwater Drone Robot (UDrobot).

The integrated conception of systems combining mechanics, electrical engineering, computer and control science constitutes a new domain, the mechatronics, that the Faculty of Engineering of the Université catholique de Louvain (UCL) has decided three years ago to teach via a new diploma in electromechanic, with an orientation in mechatronics. One of the original part of this formation is an integrated project in mechatronics, whose aim is the integration, in an unique device, of the various topics of that discipline previously taught in lectures. This paper describes this experience which has led to the realization of mobile robots able to move in a labyrinth, to pick up balls and put them in defined targets.

There are presented some aspects regarding the main designing elements of the driving kinematical joint and of the actuator. The constructive solution, an original conception, presents a series of advantages. Thus, the use of electric, hydraulic or pneumatic engines or machines was eliminated, decreasing the weight and size of the driving kinematical joint, decreasing the energetic consumption, having a simple and viable construction. In order to verify the presented device functionality the numerical simulation method of specialized SolidWorks software was used.

The ethical approach to science and technology is based on their use and application in extremely diverse fields. Less prominence has been given to the theme of the profound changes in our conception of human nature produced by the most recent developments in artificial intelligence and robotics due to their capacity to simulate an increasing number of human activities traditionally attributed to man as manifestations of the higher spiritual dimension inherent in his nature. Hence, a kind of contrast between nature and artificiality has ensued in which conformity with nature is presented as a criterion of morality and the artificial is legitimized only as an aid to nature. On the contrary, this essay maintains that artificiality is precisely the specific expression of human nature which has, in fact, made a powerful contribution to the progress of man. However, science and technology do not offer criteria to guide the practical and conceptual use of their own contents simply because they do not contain the conceptual space for the ought-to-be. Therefore, this paper offers a critical analysis of the conceptual models and the most typical products of technoscience as well as a discerning evaluation of the contemporary cultural trend of transhumanism. The position defended here consists of full appreciation of technoscience integrated into a broader framework of specifically human values.

✓ Stereotactic radiosurgery has undergone a remarkable evolution since its conception and the subsequent introduction of image-guided radiosurgery, primarily because of the concurrent advances in imaging and computer technology. However, recent improvements in real-time imaging, inverse planning techniques, and frameless alternatives have greatly enhanced the conformity and accuracy of the radiosurgical procedure. As a consequence, the possibility of hypofractionation is offered, and both intra- and extracranial targets can now be ablated with sustained submillimetric precision. Although all indispensable features, none is as impressive or useful as the incorporation of robotics, robotic beam delivery, or robotic-assisted planning, which has only served to improve the accuracy and homogeneity of therapy. The aim of this article was to describe the general technological basis of robots in radiosurgery and to review current clinical usage of robotic radiosurgery devices. Emphasis has been placed on robotic principles and the various popular applications currently available.

Within the frame of this article the author describes the potential of digital twin technology to improve the performance of real-time optimisation in complex logistics systems. After a short literature review, this paper introduces the conception of digital twin solutions. The model of digital twin supported real-time optimisation of an in-plant logistics system is described including the structure, the mathematical model, the solution algorithm, and the computational results. The scenario analysis of the described system validates the model and the efficiency of digital twin solutions.

In Celebration of the Appearance of the New Journal Ichiro Kato Ex-President, Robotics Society of Japan., Professor, Waseda University It is a great honor for me to extend my congratulations on the occasion of the foundation of this new journal of robotics and mechatronics. Although several academic societies and industrial associations in Japan publish periodicals dealing with robotics and mechatronics, there is no English edition in these fields. It is thus a breakthrough for such an English journal to be published in this country. Since I believe that the development of robotics and mechatronics will be best attained by close international cooperation, I hope this journal will contribute to the promotion of cooperation in these fields. H ere, let me introduce my commitment to robotics. I started a study on artificial hands in 1963. But as a matter of fact, I did not know then that the first industrial robots had appeared in the United States in 1962. Just after the first symposium on robotics held in Tokyo in 1967, certain kinds of robots for industrial use developed in the United States were exhibited in the Harumi Trade Centre in Tokyo. These matters ignited the research and development of robots in Japan. Robots are based on the combined technology of mechanisms and electronics, and robotics has come to play a leading role in the present industrialized world. Industrial robots now have an important place in industrial fields. I forecast that robots will coexist with mankind and assist us not only in industrial fields but also in almost all situations such as welfare and our personal lives. As is well known, Japan is one of the centers in the world for robotics and mechatronics. That is the reason why I celebrate the new publication of this journal in Japan. It will be of significance to achieve greater international exchange of information and ideas by overcoming the barrier of the Japanese language. For the prospects of future robots - my robot, a personal or domestic robot - which will appear in the 21st century, I expect that this journal will play an important role. In Celebration of the Foundation of the ""Journal of Robotics and Mechatronics"" Makoto Kajitani Professor, The University of Electro-Communications It goes without saying that most manufactured products sustammg the recent Japanese industrial growth depend on mechatronics-based technology. Born in Japan in the middle of the 1970's, ""Mechatronics"" has now become a common word in the world, attaining the concept of a central or leading technology in today's industries with its progress. To our regret, however, no mechatronics-professed journal was found either in Japan or worldwide. It is a feat of planning in order to meet the expectations of engineers and researchers engaged in the study of mechatronics in all countries that the first international journal is being published for the world in Japan from which mechatronics originated. As one of the researchers looking forward to the development of mechatronics, I wish to express my gratitude and pleasure. Mechatronics is a technology contriving to create value added through composition and fusion. Mechatronics-like conception is seen in the recent trends of industrial fields to search for new germs of alternation and fusion among different technologies or industries. We are in a time of creating new value through international fusion not only in the branch of technology but also in the spheres of politics and economy. The ultimate aim of developing mechatronics is to be of help to people's mental sufficiency and serenity. For this purpose, grounds are wanted for spiritual fusion among mechatronics engineers or researchers. I hope that this journal will not only be destined for the scientific phase but carry out an interphasic role for international intercourse among engineers and researchers. It is an undeserved honor for me to be favored on the occasion of the foundation of this journal with the opportunity to offer my congratulations. I express my heartfelt wish that this journal will play a pivotal role in interchanging information related to robotics and mechatronics. Congratulatory Messages Russell H. Taylor Editor, IEEE Transactions on Robotics and Automation Congratulations on the establishment of the International Journal of Robotics and Mechatronics. I am confident that your new journal will make a significant contribution to the wider dissemination of the considerable body of excellent research that has hitherto been published in Japanese. I am looking forward to reading it.

Energy costs play a decisive role in the operation costs of automotive production companies. Therefore, energy planning in an early conception and planning stage becomes an important topic. This is because the early conception and planning stage has the greatest potential to influence the energy consumption of manufacturing technologies since about 70-80 % of the energy costs are committed during this stage. However, lifetime cost and specifically energy consumption are currently not a determining factor at this stage. The reason is that the prediction of energy costs for complex manufacturing systems are challenging. Previous research approaches in the area of energy planning are limited to detailed planned production. A standardized approach to determine the energy consumption rates at an early stage does not exist. In this context, the EffiPLAS project has therefore proposed to solve this challenge. The aim of this project is to develop a Methods-Energy Measurement approach with elementary energy elements to support the planning process at an early stage, and to develop a modular simulation model for calculating the energy consumption of industrial robots, which complements the energy prediction. In this paper, the basic concept of elementary energy units and their value determination techniques is presented, and the simulation model is outlined. The developed approach will help to predict the prospective energy consumption of complex production equipment so that energy costs can be accounted for in an improved manner within a life-cycle costing comparative analyses.

A large variety of methods are mentioned in literature for the structural analysis and conception of parallel linkages, applicable to planar and/or spatial mechanisms developed for various applications as manipulators-robots, guiding mechanisms for car wheels and axle, solar tracking systems. Modern design requires today a unitary description of all the mechanisms in a product (including linkages) for complex simulation and optimization on software platforms. This paper proposes a seven steps general method for the parallel linkages’ structural analysis and synthesis, considered as Multibody Systems. The method is based on the concept that describes a mechanism by a minimum number of bodies. Using as input data the application area, the motion space, the mechanism mobility and the type of joints, all possible fundamental multibody chains are obtained and, based on, the corresponding mechanisms. The method is described in detail and applied for the geometrical constraints of rotational (R), spherical (S), translational (T) and their combinations types. As example, a tracking system for a solar thermal platform, based on a parallel linkage with two degrees of freedom with R, S and T joints is presented.

This paper presents a novel Continuous Variable Transmission (CVT) design. CVT is highly beneficial for actuators with rotary output as it can improve the energy efficiency of the actuators by providing an optimum transmission ratio. This property of CVT is highly beneficial for fossil-fuel-based vehicles, electric vehicles, wind turbines, industrial robots, etc. With the exception of Spherical CVT and DH CVT, all known CVTs like push belt CVTs, toroidal CVTs, Milner CVTs, etc., require additional gear sets and clutches for direction reversal and neutral gear ratio. However, Spherical CVT and DH CVT have low torque capacity due to a single traction point constraint. Foregoing in view, a new CVT named CAD CVT has been developed. The paper presents the design conception, the operating principle, the transmission ratio, the torque capacity, frictional losses, and experimental verification of the basic functionality by manufacturing a Proof of Concept (PoC). The proposed CVT is the only CVT capable of independent direction reversal and high torque capacity as it can transmit torque through multiple traction points. The new CVT will significantly impact high-torque applications in different engineering applications, especially land transport consisting of heavy vehicles like trucks, buses, and trailers.

Nowadays, we are surrounded by artifacts that are capable of adaptive behavior, such as electric pots, boiler timers, automatic doors, and robots. The literature concerning human beings’ conceptions of “traditional” artifacts is vast, however, little is known about our conceptions of behaving artifacts, nor of the influence of the interaction with such artifacts on cognitive development, especially among children. Since these artifacts are provided with an artificial “mind,” it is of interest to assess whether and how children develop a Theory of Artificial Mind (ToAM) which is distinct from their Theory of Mind (ToM). The study examined a new theoretical scheme named ToAM (Theory of Artificial Mind) by means of qualitative and quantitative methodology among twenty four 5-7 year old children from central Israel. It also examined the effects of interacting with behaving artifacts (constructing versus observing the robot’s behavior) using the “RoboGan” interface on children’s development of ToAM and their ToM and looked for conceptions that evolve among children while interacting with behaving artifacts which are indicative of the acquisition of ToAM. In the quantitative analysis it was found that the interaction with behaving artifacts, whether as observers or constructors and for both age groups, brought into awareness children’s ToM as well as influenced their ability to understand that robots can behave independently and based on external and environmental conditions. In the qualitative analysis it was found that participating in the intervention influenced the children’s ToAM for both constructors and for the younger observer. Engaging in building the robot’s behavior influenced the children’s ability to explain several of the robots’ behaviors, their understanding of the robot’s script-based behavior and rule-based behavior and the children’s metacognitive development. The theoretical and practical importance of the study is discussed.

Robotic tectonics have been integrated into the architectural profession through automated construction for more than a decade, advancing sustainability initiatives in the industry and increasing the quality of building construction. Over the years, avant-garde architects have explored the feasibility of this new design paradigm through the integration of newly-developed digital design software into automated construction. This robotic digital workflow continues to push designers to re-think the complete architecture process (from design conception to physical construction) and guides the building industry towards more precise, efficient, and sustainable development. However, in the current environment of architectural education, professional courses can be fragmented, thematic, and overly academic. Such content is not inherently compatible with the latest technological developments. The lack of understanding and application of digital technological can subsequently lead to the lack of sustainable development in architectural education. In this paper, we aim to introduce a new didactic pedagogical approach that is reliant on the principles of robotic tectonics and is defined through linear development in four distinct, developmental stages (based on information gleaned from four “Robotic Tectonics” workshops and various other rich teaching practices). This pedagogical framework provides interdisciplinary knowledge to architecture students and enables them to use advanced digital tools such as robots for automated construction, laying the groundwork for the discovery of new and complex building processes that will redefine architecture in the near future.

This paper presents an engineering method for analyzing the kinematics and inverse kinematics of a kind of Six-DOF industrial robots. Firstly, we build an engineering coordinate system for this kind robot, and then get expressions of closed-form solutions to both kinematics and inverse kinematics. From the process of deducing the expressions of closed-form solutions, we can analyze common singularities existing in workspace. Lastly, we design programs for both kinematics and inverse kinematics and simulate the movement of this kind robot. This method, compared with the structures of traditional solutions, is easier and understandability by leading into two conceptions- the position end and the tool end. What is more significant is that the robot can move safely when the wrist is under the singularity by using transitional stage. The transitional stage can make the tool of the robot move a line without join angel sudden change. The program solves the problem that all domestic industrial robots can not move when the wrist is under the singularity. This program is realized successfully on the welding robot of SIASUN Corporation.

AbstractThe paper introduces Robotic Process Automation (RPA), which is an emerging and cutting-edge conception of business processes automation, based on the notion of software robots or artificial intelligence workers. The paper is conceptual as it discusses the fundamentals behind this idea, synthesises the knowledge of technology, and presents it in a new context. It is based on the author's considerations and the literature review, which contributes to the insight into the basic understanding of RPA technology as well as systematises and clarifies RPA definitions, identifies market trends, formulates a set of predictions for further development of this technology, and highlights directions for future inquiry. Additionally, logical arguments are proposed for considering RPA as a technology that enables and advances digital transformation. Moreover, criteria are indicated for business processes suitable for RPA. Nowadays, the robotisation of business processes a s innovative technology is more often practically implemented than it is investigated by research. Published papers outline real examples of implemented cases of RPA technology in organisations that mainly represent service industries. These case studies allow identifying possible advantages and risks derived from RPA implementation. Recent studies also report benefits of the RPA application in terms of productivity, costs, service quality, and error reduction. Some authors propose the criteria for selecting processes suitable for automation and robotisation. This paper constitutes a foundation for new research aimed at filling knowledge gaps in this area. Responding to the call by van der Aalst, academic discourse on RPA must be initiated.

With the advancement in relative technology, robotics is gaining an increasing amount of attention among engineers and researchers as it is a current focus on enabling peoples lives to become more convenient. However, there is another type of robot designed very differently from functional robots like delivery robots and quadrotors that most people are familiar with, bionic robots. This is a kind of robots that gets design inspiration from real animals in nature, from the design of structure to altitudes and mechanisms of motion. How bionic robots are designed, and how the conceptional difference of bionic robots with other robots is reflected on their physical designs are the focuses of this paper. In this paper, four basic types of bionic robots are introduced and 17 existing designs of bio-inspired vehicles are included. 10 bionic aerial vehicles in 3 smaller classifications are compared to 3 conventional aerial vehicles in order to figure out differences in 3 aspects (structure design, sensors, and control method). The results show that bionic robots usually have more degrees of freedom in order to mimic animals attitudes, and are lighter in weight. Typically, bio-inspired aerial vehicles employ different wing systems compared with conventional ones. Additionally, while conventional vehicles favour PID more because of its ease of construction, bionic robots use machine learning techniques. Both types of robots use the same sensors, which is necessary for them to detect their environment. However, their control methods differ due to different purposes.

Abstract: Maintaining a power capacity of solar cell is the main thing for exercising solar power system. Most common problems in solar power system are dust, beach, creature’s pollen and crops burning. These challenges have a huge impact on the power generation capacity of solar panel. The thing of the robot's conception design is to make a machine that's easy to install, adaptable in terms of configuration, and requires lower labourers and functional charges. The robot is equipped with helical comber skirmishes which are driven by dc motor so that the robot is enforced with a water sprinkle in order to clean the panels far and wide it moves through. In this design, a system contains a length dimension unit and bedded control schemes in order to drive a movement directly and to localize the positions of the robot.

Programming activities have the potential to provide a rich context for exploring measurement units in early elementary mathematics. This study examines how a small group of young children (ages 5–6) express their emergent conception of a dynamic linear unit and the measurement concepts they found challenging. Video of an introductory programming lesson was analyzed for evidence of preconceptions and conceptions of a dynamic linear unit. Using Artifact-Centric Activity Theory as a lens for the analysis, we found that social context, gesturing, and verbal descriptions influenced the children’s understanding of a dynamic linear unit. Challenges that students encountered included developing a constructed conception of a unit, reconciling preconceptions about the meaning of a code, and socially-influenced preconceptions. This study furthers the exploration of computational thinking and mathematics connections and provides a basis for future exploration of dynamic mathematics and programming learning in early elementary education.
