Full textAbstract:
The soft fruit industry is facing unprecedented challenges due to its reliance of manual labour. We are presenting a newly launched robotics initiative which will help to address the issues faced by the industry and enable automation of the main processes involved in soft fruit production. The RASberry project (Robotics and Autonomous Systems for Berry Production) aims to develop autonomous fleets of robots for horticultural industry. To achieve this goal, the project will bridge several current technological gaps including the development of a mobile platform suitable for the strawberry fields, software components for fleet management, in-field navigation and mapping, long-term operation, and safe human-robot collaboration. In this paper, we provide a general overview of the project, describe the main system components, highlight interesting challenges from a control point of view and then present three specific applications of the robotic fleets in soft fruit production. The applications demonstrate how robotic fleets can benefit the soft fruit industry by significantly decreasing production costs, addressing labour shortages and being the first step towards fully autonomous robotic systems for agriculture.

Generally, the cyber-physical production system (CPPs) is a device that is meticulous or monitored by computer-based algorithms, firmly integrated with an Internet and its users. This system has carried with it an increasing utilization of robotics in common producing environments. One of the most important significant guidelines in the development of communication technologies and computer science and information is characterized by Cyber Physical Systems (CPSs) which are structures of collaborating computational articles which are in demanding connection with the adjacent physical world and its ongoing processes, giving and using, at the same time, data access and data process services accessible on the internet. The methodology to meet this demand is to be democratizing robotics by creating cheaper high customizable robots which can be instigated by small, medium and high enterprises. To overcome this problem, this research stares at using rapid prototyping methods for the growth of customizable robotic manipulators which can be carried out in the cyber physical production system. This study therefore contributes an approach of scheming connected and rapid prototype robotic manipulators and this methodology considers both hardware and software development mandatory for executing a robotic manipulator. Besides generative design, an evolutionary and artificial intelligence based approach is used to plan the link components between the robot joints. This component has been recognized as the ideal to be intended with this approach as its benefits most of the reproductive design approach joined with rapid prototyping. This paper also discovers a robotic manipulator control structures based on Ethernet control skills for implementation within a Cyber physical production system.

Main advances in artificial intelligence robotics are algorithms, embodied in software on the level of application software. Low-level hardware programming, electronic, and mechanics are the necessary basis to enable the implementation of newly developed algorithms. Complex autonomous systems are challenged by the tasks that require fast reactions, resulting in high accelerations and forces. These systems, therefore, generally need low masses, stiff limbs, and a precise control. To boost AI-research, more robotic systems that are appropriate to specific research questions are needed. Mechanical design is, therefore, faced with the task to provide specialized systems with a given amount of time and factors of production. This paper outlines an approach to increase the efficiency of engineering design in the field of robotics by analyzing the bilateral influence of the system concept with embodiment design driven by the state of the art small-batch manufacturing technologies. The humanoid robotic system AILA is presented and the selected steps out of its design process are discussed. A way to clearly state the axioms and requirements that the developed system is based on is presented. The resulting dependencies lead to the embodiment design of the systems components, which are also influenced by the choice of suitable manufacturing technologies.

Nowadays, in the modern manufacturing factories and in the companies engaged in the robotic cells manufacture it is necessary to optimize the production time, diagnostics and commissioning of the control system. The control system should meet with several criteria for the functionality and transparency. These criteria can be achieved by introducing the program control standardization. Well designed and tested control algorithms can reduce the time needed for the preparation and commissioning of the robotic cell. Ultimately, costs reduction for the preparation of such robotic cell, transparency and rapid response for errors diagnostics in the control system will be achieved.

They analyzed the assortment of machines for dairy farming. Based on the results of simulation in the Any Logic software, they proposed the concepts of robotic milking systems. They compared the throughput when performing milking service operations with robotic types of milking machines and standard systems operated by the manipulator.(Results and discussion) The authors performed calculations and gave a comparative assessment of the duration of the service cycles for animals in automated and robotic milking parlors of various configurations: “Fan”, “Herring-bone”, “Parallel”. To reduce the capital intensity of robotic facilities, to increase the level of production process execution accuracy, to reduce the time required to service animals, a robotic animal sanitation system was proposed at the entrance to the milking parlor. The authors proved that the introduction of the proposed configuration of robotic milking parlors would reduce the capital intensity of equipment in comparison with single-box models of robotic milking stations. They noted the advantages of such systems: the general infrastructure of the component base (milk pipelines, milk receivers, automatic rinsing, etc.) and was not separated by different streams.(Conclusions) The authors revealed the optimal ratio of the number of milking posts and medical stations – 13:1. It was proved that it provided maximum labor productivity for a robotic milking parlor. According to the results of theoretical calculations, it was determined that the proposed robotics schemes for milking parlors exceed the productivity of existing single-box robotic milking stations.

Full textAbstract:
This work presents a concept for autonomous mobile manipulation in industrial environments. Utilizing autonomy enables an unskilled human worker to easily configure a complex robotics system in a setup phase before carrying out fetch and carry operations in the execution phase. In order to perform the given tasks in real industrial production sites, we propose a robotic system consisting of a mobile platform, a torque-controlled manipulator, and an additional sensor head. Multiple sensors are attached which allow for perception of the environment and the objects to be manipulated. This is essential for coping with uncertainties in real-world application. In order to provide an easy-to-use and flexible system, we present a modular software concept which is handled and organized by a hierarchical flow control depending on the given task and environmental requirements. The presented concept for autonomous mobile manipulation is implemented exemplary for industrial manipulation tasks and proven by real-world application in a water pump production site. Furthermore, the concept has also been applied to other robotic systems and other domains for planetary exploration with a rover.

In the race of man v/s machine, automation comes as a companion of man and machine. Taking the technology to the next level from the mobile driven world to an automation driven world, will increase manufacturers their production rates, productivity and efficiency with materials, product quality, and worker safety. From ancient times the ingenuity and the brain power human beings have astonished researchers with engineering and mechanical marvels like the wheel, bow and arrow, cross bows, etc. What started from the wheel did not end there but evolved into the complex mechatronics systems that we see around us today. The robotics is one such human marvel that will be one-day equal human beings themselves. The robots thus have far more use in the daily life than any other systems. The robotics and automation is a rising piece of technology which could lessen the loads of work and solve the problems exponentially. As robotics is finding its place on every sector in this globe, the aim this project is to introduce robotics in the field of industry. The title of the system is ‘Gesture controlled robotic arm’. The aim of the system is to provide safety and to increase productivity in our industries. The research project should be designed in such a way that it should occupy minimum space, should possess high maneuverability and high agility. The project in discussion is types of robots which needs minimum space and are proved to be highly maneuverable and highly agile. The robot contains two main units, one is the robotic arm and second is the data glove with accelerometer using a RF controller. The robotic arm unit is responsible for the hand functions of the whole structure of the robot. The data glove is responsible for the input feedback to the robotic arm. The robotic unit will be controlled by an Arduino platform to improve its stability. The angle tilt will be measured using ADXL335 sensor. The ADXL335 uses angle, tilt and yaw values with Arduino for data transfer. Through advanced primary and secondary research techniques, system implementation hurdles and potential risks involved in developing such a system are identified. The project is fully planned using advanced project management techniques like PERT chart and Gantt chart in order to identify the critical activities and the timeline related with it.

Automated solutions for fresh market fruit and vegetable harvesting have been studied by numerous researchers around the world during the past several decades. However, very few developments have been adopted and put into practice. The reasons for this lack of success are due to technical, economic, horticultural, and producer acceptance issues. The solutions to agricultural robotic mechanization problems are multidisciplinary in nature. Although there have been significant technology advances during the past decade, many scientific challenges remain. Viable solutions will require engineers and horticultural scientists who understand crop-specific biological systems and production practices, as well as the machinery, robotics, and controls issues associated with the automated production systems. Focused multidisciplinary teams are needed to address the full range of commodity-specific technical issues involved. Although there will be common technology components, such as machine vision, robotic manipula-tion, vehicle guidance, and so on, each application will be specialized, due to the unique nature of the biological system. Collaboration and technology sharing between commodity groups offers the benefit of leveraged research and development dollars and reduced overall development time for multiple commodities. This paper presents an overview of the major horticultural and engineering aspects of robotic mechanization for horticultural crop harvesting systems.

The concept of an intelligent control system for a complex nonlinear biomechanical system of an extension cableless robotic unicycle is considered. A thermodynamic approach to study optimal control processes in complex nonlinear dynamic systems is used. The results of stochastic simulation of a fuzzy intelligent control system for various types of external/ internal excitations for a dynamic, globally unstable control object -extension cableless robotic unicycle based on Soft Computing (Computational Intelligence Toolkit) technology are presented. A new approach to design an intelligent control system based on the principle of the minimum entropy production (minimum of useful resource losses) determination in the movement of the control object and the control system is developed. This determination as a fitness function in the genetic algorithm is used to achieve robust control of a robotic unicycle. An algorithm for entropy production calculation and representation of their relationship with the Lyapunov function (a measure of stochastic robust stability) is described.

Advanced manufacturing systems allow rapid changes of production processes by means of reconfigurability providing mass customisation of products with high productivity, quality and low costs. Reconfigurable Manufacturing Systems (RMS) employ conventional as well as special purpose CNC machines, robots and material handling systems. In customised automated assembly, a number of different workpieces need to be processed simultaneously at various workstations according to their process plans. Therefore, a material handling system is an important part of RMS, whose main task is to provide reliable, accurate and efficient transfer of materials according to the process scheduling, without bottlenecks and stoppages. In this research, a reconfigurable pallet system was developed to facilitate automated robotic assembly for a highly customised production environment. The aim is to design a material handling system for conveying, sorting and processing of parts, which are supplied by robots and part feeders in different configurations. The developed pallet system provides a low-cost solution and it includes four flexible conveyors and part handling devices. All the elements of the system were successfully integrated with an intelligent controller. A user-friendly human machine interface provides easy reconfigurability of the pallet system and interfacing with robots, processing stations and part feeding sub-systems. The main advantages of the developed material handling system are the ease of operation, its reconfigurability and low-cost. The system demonstrates the advantages of reconfigurable material handling systems and it can be employed for training purposes.

The development of robotics and the roboti technologies in modern economy has a significant impact on change of the enterprises requirement in human resources and also on change of employers’ requirements to professional competences of staff. In the long term, labor market will impose increased requirements to staff on possession of professional competences, on interaction with robotics in a workplace, including the ability to control the equipment, to carry out monitoring of production operations observance and be able to adapt to changes in production process taking into account functionality of robotics. According to various research and polls, the modern system of staff training does not provide the study of such professional competences. In the long term, it can result in discrepancy of the young specialists’ competence that completed training in the programs of secondary professional education, and forming the offer in labor market, to those requirements which are imposed from employers. In these conditions transformation of the staff training system which will be focused, first of all, on the formation of those competences which will allow young specialists not only to use the available equipment, but to have an opportunity to master new technologies. The paper outlines the problem of incompliance of the level of young specialists training and the current trends of robotics development on the basis of statistical data and results of the available research.

At present, the production lines of mobile phones are mainly manual and semi-automatic. Robots are the most important tools used to improve the intelligence level of industry production. The design of an intelligent robotic assembly system is presented in this paper, which takes the assembly of screen components and shell components as examples. There are major factors restricting the application of robots, such as the calibration of diversified objects, the moving workpiece with incomplete information, and diverse assembly types. A method was proposed to solve these technological difficulties. The multi-module calibration method is used to transform the pose relationship between the robot, the conveyor belt, and the two cameras in the robot assembly system. Aiming at a workpiece moving with incomplete information, the minimum matrix method is proposed to detect the position. Then dynamic fetching is realized based on pose estimation of the moving workpiece. At last, the template matching method is used to identify the assembly area of the workpiece type. The proposed method was verified on a real platform with a LINKHOU LR4-R5 60 robot. Results showed that the assembly success rate was above 98%, and the intelligent assembly system of the robot can realize the assembly of mobile phone screens and back shells without any staff.

Full textAbstract:
Flexible production is a key element in modern industrial manufacturing. Autonomous mobile manipulators can be used to execute various tasks: from logistics, to pick and place, or handling. Therefore, autonomous robotic systems can even increase the flexibility of existing production environments. However, the application of robotic systems is challenging due to their complexity and safety concerns. This paper addresses the design and implementation of the autonomous mobile manipulator OMNIVIL. A holonomic kinematic design provides high maneuverability and the implemented sensor setup with the underlying localization strategies are robust against typical static and dynamic uncertainties in industrial environments. For a safe and efficient human–robot collaboration (HRC), a novel workspace monitoring system (WMS) is developed to detect human co-workers and other objects in the workspace. The multilayer sensor setup and the parallel data analyzing capability provide superior accuracy and reliability. An intuitive zone-based navigation concept is implemented, based on the workspace monitoring system. Preventive behaviors are predefined for a conflict-free interaction with human co-workers. A workspace analyzing tool is implemented for adaptive manipulation, which significantly simplifies the determination of suitable platform positions for a manipulation task.

Full textAbstract:
Pruning is one of the most important tree fruit production activities, which is highly dependent on human labor. Skilled labor is in short supply, and the increasing cost of labor is becoming a big issue for the tree fruit industry. Meanwhile, worker safety is another issue in the manual pruning. Growers are motivated to seek mechanical or robotic solutions for reducing the amount of hand labor required for pruning. Identifying tree branches/canopies with sensors as well as automated operating pruning activity are the important components in the automated pruning system. This paper reviews the research and development of sensing and automated systems for branch pruning in apple production. Tree training systems, pruning strategies, 3D structure reconstruction of tree branches, and practice mechanisms or robotics are some of the developments that need to be addressed for an effective tree branch pruning system. Our study summarizes the potential opportunities for automatic pruning with machine-friendly modern tree architectures, previous studies on sensor development, and efforts to develop and deploy mechanical/robotic systems for automated branch pruning. We also describe two examples of qualified pruning strategies that could potentially simplify the automated pruning decision and pruning end-effector design. Finally, the limitations of current pruning technologies and other challenges for automated branch pruning are described, and possible solutions are discussed.

Digital technologies have been deeply integrated into our lives and found their application in all areas of human activity, including agriculture. Technological progress, the development of infrastructure in the IT industry, wider access to the Internet, a high level of education and growing computer literacy of the population contribute to the popularization and introduction of digital technologies in agricultural production. The review of the use of digital technologies in the agricultural sector has shown that existing software tools help plan the work of an agricultural organization, monitor the state of production, manage the farm, and sell products on virtual trading platforms. Most software products are able to store data in the cloud, and farmers can access the system via their personal account from any device with Internet access. There are also a number of programs on the market that allow farmers to plan, analyze and control the crop or livestock production. Leading manufacturers of agricultural machinery and equipment are actively integrating digital technologies into their products. It is now possible to manage a fl eet of vehicles used in the fi elds, and implement unmanned control. Use can be made of tractors equipped with automatic systems for driving along rows or laid paths, turning, and monitoring process parameters. The authors propose a set of digital control means to be used in agricultural production, based on the application of technologies of the Internet of things, cloud data storage, big data processing, and artifi cial intelligence. It is the technologies that digital agriculture will be based on, which use robotic monitoring tools to collect information and transmit it to “cloud data storage”. It is processed there and directed to the control system, which develops the optimal solution and transmits the control signal to the robotic actuators. In this regard, the development of agricultural machinery should be focused on the robotic tools designed for monitoring and performing technological operations. The most diffi cult task is to develop a control system, since it must have elements of artifi cial intelligence and replace humans in agricultural production.

In the process of creating modern production, it is necessary to reduce the marriage associated with the human factor to zero, by reducing the number of operations carried out by people, leveling the mistakes that a person can make. So one of the solutions to this problem is the creation of robotic systems in which all operations are performed without any operator intervention. To control the execution of operations by a robotic system, in some cases, it is possible to use various sensors and sensors, but sometimes it turns out to be too expensive and difficult, therefore, the authors demonstrated the implementation of control over automation implemented using computer vision systems. Also, in the work, an analogy is drawn between computer vision and physical sensors, using the example of solving the problem that the authors faced.

Full textAbstract:
Introduction. Development of construction technologies and materials entails the use of larger and heavier aercrete blocks. Hence, it promotes construction industry automation through the use of robotic systems. Due to considerable costs of development, production and operation of robotic systems capable of substituting human workers at a construction site, thorough substantiation of their efficiency (or investment appeal) is required. It encompasses the calculation of total costs and the timing of its development and implementation, since no universal comprehensive solutions are available now.
Materials and methods. The co-authors have summarized practical design and engineering problems that may accompany the development of novel machinery and preparation of investment projects towards development of a construction robotic system (CRS) designated for aircrete block laying in the course of construction of buildings and structures. Two groups of experts were involved, Group One had civil engineers and Group Two had designers of robotic and mechatronic systems. Methods of expert evaluations and mathematical statistics were used; the co-authors also addressed specialized Internet websites and publications on design and engineering solutions.
Results. A list of criteria describing the performance of a robotic system was made with a focus on most important factors. The co-authors identified a set of parameters whose availability in a robotic system ensures ideal blockwork. The co-authors have developed a technical specification for a robotic system, identified its cost and developed an implementation schedule.
Conclusions. A formalized description of the future CRS, designated for construction purposes, is provided for the period of concept development. The co-authors also provided a reliable assessment of potential costs and schedules at the problem statement stage (a feasibility study), as it is important for the assessment of implementability of investment processes (a business plan) in terms of making a decision to initiate project implementation.

Construction of a large ship requires many thousands of feet of welding. Whenever the welding process can be streamlined or automated, tremendous cost savings can be obtained. The WELDEXCELL system is a WELDing EXpert manufacturing CELL that provides computerized technical support information, off-line weld planning, and an integrated welding robot/welding system/vision system controller. The first of two subsystems, the Welding Job Planner (WJP) accomplishes off-line intelligent weld planning for both automated and manual welding processes. The second subsystem, the Welding Job Controller (WJC) provides a fully integrated hardware control environment with associated software for combined control of a welding robot, welding equipment, and a robotic vision system. In the WELDEXCELL system, a series of expert systems and databases have been combined in a new type of computer software environment called a blackboard. There are as many as 19 separate components of the Welding Job Planner subsystem of WELDEXCELL which fall into five interrelated functional groups. WELDEXCELL will be used by design engineers, welding engineers, mechanical engineers, and nondestructive testing (NDT) engineers for both manual welding and to interface to automated and robotic welding systems and vision systems. WELDEXCELL also includes the control system hardware and software to provide off-line intelligent adaptive control of the welding process itself. The development of WELDEXCELL is a multi-year effort involving a partnership of government, industry, university research, and technology transfer. The project has already generated new concepts with potential for future spin-off benefits. The ultimate payback in productivity will be large for the American welding, fabrication, manufacturing, and construction industries.

A necessary condition for a sharp increase in production is the introduction of digital smart technologies. With the use of digital technologies, it is possible to achieve a significant increase in labor productivity and crop yields, reduce energy and material costs. Digital machine technologies should be used in crop production, animal husbandry, power engineering, storage and processing of agricultural products. The effective production development requires a comprehensive system of management of agricultural enterprises, which, based on the obtained data, will ensure timely and correct processing.
In digital machines and agricultural technologies, four main areas can be identified: monitoring of environment and parameters of processes; transmission and storage of information; artificial intelligence and cloud technologies; implementation of management decisions by robotic technical means. The main objects of monitoring are soils, plants, animals, weather and climatic conditions, technical means, and technological processes. Ground and air monitoring tools receive and transmit real-time data to the cloud platform. Artificial intelligence optimizes technological operations and gives a command to the actuators using the monitoring data.

Full textAbstract:
In industrial production systems, manufacturers often face difficulties in sorting different types of objects. Color and height-based sorting which is done manually by human is quite a tedious task and its needs countless time as well. For manual sorting, many workers are required, which can be quite expensive. Moreover, robots that can sort only color or height can’t be effective when there is a need of products with same color with different heights and vice versa. In this paper, a computer vision based robotic sorter is proposed, which is capable of detecting and sorting objects by their colors and heights at the same time. This work isn’t done before as height sorting of same shapes is a new technique, which is done with color sorting techniques by computer vision. It is equipped with a robotic arm having 6 degree of freedom (DOF), by which it picks up and then place objects according to its color and height, to a predetermined place as per the production system requirement. A camera with the computer vision software detects various colors and heights. Haar Cascade algorithm has been used to sort the products. This multi-DOF robotic sorter can be a remarkably useful tool for automating the production process completely, where multiple conveyor belts are used, which can reduce time complexity as well. In the proposed system, the efficiency of color and height sorting is around 99%, which proves the efficiency of our system. The overall improvement in the efficiency of the production process can be significantly enhanced by using this system.

Technology development and growing competition have an influence on production growth and increase of product quality, and thus the new possibilities in innovation of industrial robot are searched for. One of the possibilities is applying of an inertial navigation system into robot control. This article focuses on new trends in manufacturing technology: design of Inertial Measurement Unit (IMU) for a robotic application control. The Arduino platform is used for the IMU as a hardware solution. The advantage of this platform is low cost and wide range of sensors and devices that are compatible with this platform. For scanning, the MEMS sensor MPU6050 is used, which includes a 3-axis gyroscope and an accelerometer in one chip.

AbstractA markerless system for the registration of a bone’s pose is presented which reduces the setup time and the damage to the bone to a minimum. For the registration, a particle filter is implemented which is able to estimate a bone’s pose using depth images. In a phantom study, the pose of 3D-printed bones has been estimated at a rate of 90 Hz and with a precision of a few millimeters. The particle filter is stable under partial occlusions and only diverges when the bone is fully occluded. During a cadaver study, the preoperatively planned cutting edges have been projected as augmented reality (AR) templates onto the hip bones of five cadavers. By cutting manually along the AR templates, surgeons were able to extract ten transplants in the same time as with conventional osteotomy templates. Using the presented navigation system can save hours spent on the construction and production of conventional templates. In conclusion, this work represents one step towards a broader acceptance of robotic osteotomies.

Virtual Commissioning (VC) is a method and tool for verifying and testing the PLC control program on a virtual digital model of the manufacturing system. It allows to visualize and test the control system before the real commissioning of the production systems. The aim of the research is to implement virtual reality (VR) into the VC method and to verify the mutual interaction of signals between the simulation in VR environment, the digital model of the production system and the control system. The introduction of VR in VC increases the concept by adding more realistic visualization and tracking, which extends its validation capabilities. The changes made in VR virtual environment are transferred to the simulation model and can be validated in a real production system. The real production robotic system transformed into a virtual form will be a case study with its verification. Also will be tested security protocols and proven human interaction with the system to control the system through the virtual HMI (virtual user interface) using VR.

Sheep body segmentation robot can improve production hygiene, product quality, and cutting accuracy, which is a huge change for traditional manual segmentation. With reference to the New Zealand sheep body segmentation specification, a vision system for Cartesian coordinate robot cutting half-sheep was developed and tested. The workflow of the vision system was designed and the image acquisition device with an Azure Kinect sensor was developed. Furthermore, a LabVIEW software with the image processing algorithm was then integrated with the RGBD image acquisition device in order to construct an automatic vision system. Based on Deeplab v3+ networks, an image processing system for locating ribs and spine was employed. Taking advantage of the location characteristics of ribs and spine in the split half-sheep, a calculation method of cutting line based on the key points is designed to determine five cutting curves. The seven key points are located by convex points of ribs and spine and the root of hind leg. Using the conversion relation between depth image and the space coordinates, the 3D coordinates of the curves were computed. Finally, the kinematics equation of the rectangular coordinate robot arm is established, and the 3D coordinates of the curves are converted into the corresponding motion parameters of the robot arm. The experimental results indicated that the automatic vision system had a success rate of 98.4% in the cutting curves location, 4.2 s time consumption per half-sheep, and approximately 1.3 mm location error. The positioning accuracy and speed of the vision system can meet the requirements of the sheep cutting production line. The vision system shows that there is potential to automate even the most challenging processing operations currently carried out manually by human operators.

In the rapid spray metal tooling, metal film is spray-formed on the substrate and supported under the back, which will act as the working surface of the rapid metal tool finally. So the finishing process for the sprayed metal film is important to the quality and the lifecycle of the rapid metal tool. The finishing of the metal mould is frequently carried out manually, these kinds of operations are iterative, time consuming and require experience. Automation can introduce cost reduction minimizing production times on such manual finishing operations. This paper presents a robotic polishing system with free abrasive for the finishing of the rapid spray metal tool, which is consisted of a six-degree-of-freedom industrial robot manipulator, a high speed electrical polishing spindle and a numerical swivel table. Soft polishing pad and free abrasive are also selected for the robotic polishing system. The path planning is so important to the robotic polishing system that a partition & flexible path mapping method basing on UG CAM is developed to generate the uniform robotic polishing path on the complex mould surface. UG/Open GRIP programming module is used to generate the driving paths with different path intervals on the predesigned plane for each partitioned part. When the driving paths are projected to the mould curved surface, the uniform polishing paths with NC code can be generated by the multi-axis CAM module of the UG. And the path with NC code can then be transformed to the robotic polishing path. According to the elastic deformation and the abrasion of the soft polishing tool, the robotic polishing path should be adjusted to keep the smooth polishing process by offsetting the pre-compressed value and the abrasive compensation value along the polishing axis direction. Technical parameters of the robotic polishing process are also optimized through the experiments. Finally, the rapid metal punch mould is finished to test the robotic polishing system.

AbstractThis research presents a cooperative heterogeneous multi-robot fabrication system for the spatial winding of filament materials. The system is based on the cooperation of a six-axis robotic arm and a customized 2 + 2 axis CNC gantry system. Heterogeneous multi-robot cooperation allows to deploy the strategy of Spatial Winding: a new method of sequential spatial fiber arrangement, based on directly interlocking filament-filament connections, achieved through wrapping one filament around another. This strategy allows to create lightweight non-regular fibrous space frame structures. The new material system was explored through physical models and digital simulations prior to deployment with the proposed robotic fabrication process. An adaptable frame setup was developed which allows the fabrication of a variety of geometries within the same frame. By introducing a multi-step curing process that integrates with the adaptable frame, the iterative production of continuous large-scale spatial frame structures is possible. This makes the structure’s scale agnostic of robotic reach and reduces the necessary formwork to the bare minimum. Through leveraging the capacities of two cooperating machines, the system allows to counteract some of their limitations. A flexible, dynamic and collaborative fabrication system is presented as a strategy to tailor the fiber in space and expand the design possibilities of lightweight fiber structures. The artifact of the proposed fabrication process is a direct expression of the material tectonics and the robotic fabrication system.

The solution to the problem of automating the process of collecting agricultural products based on models, algorithms and multicriteria synthesis of the configuration of robotic capture and control of its software and hardware components during physical manipulations with objects of agricultural products is discussed. Performing monotonous physically difficult operations in agricultural pro-duction leads to the risk of disorders of the musculoskeletal system of workers, therefore, the use of robotic means for physical contact and manipulation with objects in agricultural production is an urgent task that ensures a reduction in the cost of production, an increase in the quality of operations performed and the labor safety of involved specialists. The variability of the physical and geometric characteristics of the fruits and the methods of their collection does not allow the creation of univer-sal robotic grippers, therefore, active research is currently underway on the design of robotic grip-pers for manipulating the fruits of individual crops, differing in weight, density, geometry, surface roughness and other parameters. The article describes the developed conceptual model of robotic gripper control, including the description of the manipulator, gripper, sensor system and the manip-ulated object of agricultural products with various forms, physical and mechanical properties. The article analyzes the physical and mechanical properties of some vegetables and fruits, methods of cutting off the fruit, which should be taken into account when developing robotic grippers. There were discussed a four-stage technique for determining the parameters of robotic gripping, including determining the characteristics of the manipulated object; characteristics of the working environ-ment; determination of the features of the manipulator on which the gripper is planned to be in-stalled, and evaluation of the efficiency of the projected gripper according to a number of criteria. The developed algorithmic model of the choice of configuration parameters for robotic gripping of agricultural products is presented. It provides, based on the analysis of the properties of the manipu-lated object, the development of requirements for the configuration and gripping control system.
