Повний текст джерелаThis work deals with the simulation and the validation of complex manipulation tasks under strong geometric constraints in virtual environments. The targeted applications relate to the industry 4.0 framework; as up-to-date products are more and more integrated and the economic competition increases, industrial companies express the need to validate, from design stage on, not only the static CAD models of their products but also the tasks (e.g., assembly or maintenance) related to their Product Lifecycle Management (PLM). The scientific community looked at this issue from two points of view: - Task planning decomposes a manipulation task to be realized into a sequence of primitive actions (i.e., a task plan) - Path planning computes collision-free trajectories, notably for the manipulated objects. It traditionally uses purely geometric data, which leads to classical limitations (possible high computational processing times, low relevance of the proposed trajectory concerning the task to be performed, or failure); recent works have shown the interest of using higher abstraction level data. Joint task and path planning approaches found in the literature usually perform a classical task planning step, and then check out the feasibility of path planning requests associated with the primitive actions of this task plan. The link between task and path planning has to be improved, notably because of the lack of loopback between the path planning level and the task planning level: - The path planning information used to question the task plan is usually limited to the motion feasibility where richer information such as the relevance or the complexity of the proposed path would be needed; - path planning queries traditionally use purely geometric data and/or “blind” path planning methods (e.g., RRT), and no task-related information is used at the path planning level Our work focuses on using task level information at the path planning level. The path planning algorithm considered is RRT; we chose such a probabilistic algorithm because we consider path planning for the simulation and the validation of complex tasks under strong geometric constraints. We propose an ontology-based approach to use task level information to specify path planning queries for the primitive actions of a task plan. First, we propose an ontology to conceptualize the knowledge about the 3D environment in which the simulated task takes place. The environment where the simulated task takes place is considered as a closed part of 3D Cartesian space cluttered with mobile/fixed obstacles (considered as rigid bodies). It is represented by a digital model relying on a multilayer architecture involving semantic, topologic and geometric data. The originality of the proposed ontology lies in the fact that it conceptualizes heterogeneous knowledge about both the obstacles and the free space models. Second, we exploit this ontology to automatically generate a path planning query associated to each given primitive action of a task plan. Through a reasoning process involving the primitive actions instantiated in the ontology, we are able to infer the start and the goal configurations, as well as task-related geometric constraints. Finally, a multi-level path planner is called to generate the corresponding trajectory. The contributions of this work have been validated by full simulation of several manipulation tasks under strong geometric constraints. The results obtained demonstrate that using task-related information allows better control on the RRT path planning algorithm involved to check the motion feasibility for the primitive actions of a task plan, leading to lower computational time and more relevant trajectories for primitive actions

Повний текст джерелаIn this thesis, we were interested in the control of industrial manipulators in co-manipulation mode with a human operator for the handling of heavy loads. First, we have presented an overview of existing studies in this framework. Then, we have addressed the modeling and the identification of dynamic parameters for the Denso VP-6242G robot. We have used the OpenSYMORO software to calculate its dynamical model. After a detailed presentation of the method for identifying the robot's parameters, we have applied it to the case of our robot. This allowed us to obtain a vector of the parameters which guarantees a positive definite inertia matrix for any configuration of the robot, as well as a good quality of reconstruction of the torques in the case of constant joint velocities or in the case of variable ones over time. To continue, we have detailed the new features that have been proposed for the online trajectory generator, for which the control scheme is based on. We have presented a method for estimating the operator's force from the measurements of the interaction force between the robot and the operator, while taking into account for the penalization of the operator's force in order to have an information of this last which allows to generate a trajectory that respects the limits of workspace. Some tests of the trajectory generator simulating different possible scenarios have allowed us to check the effectiveness of the new proposed features. The generator makes it possible to produce a trajectory in the three-dimensional workspace according to the direction of the force applied by the operator, which contributes to fulfill the requirement of transparency that is sought in a co-manipulation. In the last part, we have presented and validated, in simulation, an impedance control whose reference trajectories are delivered by the proposed generator. The obtained results have shown a good trajectory tracking. On the other hand, the satisfaction of the virtual bounds of the workspace has also been nicely taken into account. However, the corresponding articular trajectories can cross the bounds defined to preserve the integrity of the robot

Повний текст джерелаThis PhD thesis explores the development and implementation of URNik-AI, an AI-powered automated depalletizing system designed to handle cardboard boxes of varying sizes and weights using a dual-arm humanoid torso. The primary objective is to enhance the efficiency, accuracy, and reliability of industrial depalletizing tasks through the integration of advanced robotics, computer vision, and deep learning techniques.The URNik-AI system consists of two UR10 robotic arms equipped with six-axis force/torque sensors and gripper tool sets. An ASUS Xtion RGB-D camera is mounted on Dynamixel Pro H42 pan-tilt servos to capture high-resolution images and depth data. The software framework includes ROS Noetic, ROS 2, and the MoveIt framework, enabling seamless communication and coordination of complex movements. This system ensures high precision in detecting, grasping, and handling objects in diverse industrial environments.A significant contribution of this research is the implementation of deep learning models, such as YOLOv3 and YOLOv8, to enhance object detection and pose estimation capabilities. YOLOv3, trained on a dataset of 807 images, achieved F1-scores of 0.81 and 0.90 for single and multi-face boxes, respectively. The YOLOv8 model further advanced the system's performance by providing keypoint and skeleton detection capabilities, which are essential for accurate grasping and manipulation. The integration of point cloud data for pose estimation ensured precise localization and orientation of boxes.Comprehensive testing demonstrated the system's robustness, with high precision, recall, and mean average precision (mAP) metrics confirming its effectiveness. This thesis makes several significant contributions to the field of robotics and automation, including the successful integration of advanced robotics and AI technologies, the development of innovative object detection and pose estimation techniques, and the design of a versatile and adaptable system architecture

Повний текст джерелаThis Master's thesis presents the design and experimental validation of a mechatronic system aimed at facilitating the handling of heavy components in industrial assembly situations, for example the assembly of aircraft fuselage panels. The principle of underactuated redundancy is used to make the interaction between the human operator and the robot safe, intuitive and responsive, while allowing a relatively high payload. This principle consists in using a low-impedance passive mechanism paired with an active system with a payload directly attached to the passive mechanism's end e ector. In the operation of the device, the human operator directly manipulates the payload and thereby induces movements in the passive mechanism. The measured joint variables in the passive mechanism are then used to control the high-impedance active joints of the robot. In previous works, the principle of underactuated redundancy has been applied to translational movements. The aim of this Master's thesis is therefore to apply the principle of underactuated redundancy to rotations in order to rotate a payload in three-dimensional space. First, the principle is applied to a one-degree-of-freedom planar manipulator in order to evaluate the validity of the concept for rotational motions. Then, it is applied to a two-degree-of-freedom spatial manipulator. Active counterweights are used to statically balance the two manipulators. It should be noted that the last rotational motion is not studied since it is easy to implement; static balancing is not required for the rotation around the vertical axis. Subsequently, the rotational system obtained previously is combined with an existing translational system with the objective of freely manipulating a payload in six-dimensional space. The experimental validations are presented to show that the manipulator is safe, intuitive and responsive for the human operator.

Повний текст джерелаThe aim of the thesis is the design and analysis of portable systems for rehabilitation of motor functions of humans, based on the manipulation mechanisms with improved weight, calibration and energy consumption characteristics. The work deals with the development of new electromechanical rehabilitation devices containing electroactive polymer-metal-composite elements intended for rehabilitation and maintenance of human motor functions, and modelling, analysis and design of their biomechatronic systems. A new method for an accurate balancing of biomechanical system using springs, counterweights and auxiliary links is proposed, providing also a load adjustment system. It is applicable with spring with any characteristic and allows not only the reduction of the oscillations of the moment of the gravitational forces of the counterweight, but also the control of its law of variation. The dynamic modelling, the development of an optimal design and the control methodology of human extremity exoskeleton with electromechanical actuators are performed, using Lagrange-Maxwell equations. The numerical examples for determination of laws of variation of electrical control voltages and powers in the exoskeleton’s actuators showed the effectiveness of the proposed methods. The proposed method of optimal dynamic design and the computational algorithms were successfully tested on an illustrative example of optimal control problem. The variation of the generalized coordinates, the electrical control voltages and the powers of actuators due to minimum power inputs criterions were determined. Appropriate actuators were selected. As a result, the power inputs have been significantly reduced. The methodology of design for the rehabilitation systems with application of modern electroactive conducting polymer-metal composite actuators is proposed and tested

Повний текст джерелаBacillus cereus, responsible for food toxi-infections, frequently contaminates heated-processed foods. Indeed, beyond its resistance to heat and chemical treatment, the B. Cereus spore possesses a strong capacity to adhere to inert materials such as steel and therefore may be considered as a major food contamination risk. Mastery of equipment hygiene requires a deeper knowledge of factors which influence B. Cereus spores' adhesion capacity and their resistance to cleaning techniques. The adhesion of micro-organisms is linked to their surface properties, which may vary according to the environmental conditions they encounter. Ln the course of this study, we reveal a wide variability in surface properties (morphology, hydrophobia, surface protein content) from one spore strain to another. These differences are associated with a significant variability in each strain's capacity to adhere to steel and in its resistance to cleaning-in-place (CIP). Close examination of these data has shown that the longer their appendages, the stronger the spores' adhesion, whereas resistance to cleaning-in-place is inversely proportional to the size of the exosporia. The use of mutants (from B. Cereus and B. Anthracis) allowed us to show that brush-like exosporial filaments (made up of BclA) inhibit resistance to cleaning. An absence of the ExsY protein stops the exosporium from developing and leads to a consequent decrease in adhesion and an increase in resistance to cleaning. Thus, surface contamination risk is higher for strains with long appendages and small exosporia. Furthermore, spores' surface properties are affected by the conditions encountered by the bacteria. We have studied the influence of conditions likely to be encountered by spores in the agro-food industry. Sporulation at high temperature and sporulation in a liquid environment respectively affect the exosporium's size and integrity and result in lesser adhesion. Ln addition, the application of hydrodynamic conditions close to those encountered in the agro-food industry, induces greater or lesser damage to the exosporia according to the conditions in which they sporulated. This damage leads to a decrease in spore adhesion coupled with an increase in their resistance to eleaning. These behavioural differences must therefore be taken into account in analytical procedures applied in the determination of risk associated with the presence of B. Cereus

Повний текст джерелаDeformable objects are ubiquitous in our daily lives. On a given day, we manipulate clothes into uncountable configurations to dress ourselves, tie the shoelaces on our shoes, pick up fruits and vegetables without damaging them for our consumption and fold receipts into our wallets. All these tasks involve manipulating deformable objects and can be performed by an able person without any trouble, however robots have yet to reach the same level of dexterity. Unlike rigid objects, where robots are now capable of handling objects with close to human performance in some tasks; deformable objects must be controlled not only to account for their pose but also their shape. This extra constraint, to control an object's shape, renders techniques used for rigid objects mainly inapplicable to deformable objects. Furthermore, the behavior of deformable objects widely differs among them, e.g. the shape of a cable and clothes are significantly affected by gravity while it might not affect the configuration of other deformable objects such as food products. Thus, different approaches have been designed for specific classes of deformable objects.In this thesis we seek to address these shortcomings by proposing a modular approach to sense the shape of an object while it is manipulated by a robot. The modularity of the approach is inspired by a programming paradigm that has been increasingly been applied to software development in robotics and aims to achieve more general solutions by separating functionalities into components. These components can then be interchanged based on the specific task or object at hand. This provides a modular way to sense the shape of deformable objects.To validate the proposed pipeline, we implemented three different applications. Two applications focused exclusively on estimating the object's deformation using either tactile or force data, and the third application consisted in controlling the deformation of an object. An evaluation of the pipeline, performed on a set of elastic objects for all three applications, shows promising results for an approach that makes no use of visual information and hence, it could greatly be improved by the addition of this modality

Повний текст джерелаMobilmanipulatorer förändrar sättet som företag och industrier utför sitt arbete. Otränade slutanvändare och särskilt de utan programmeringskunskap kommer att bemötas av icke-funktionella och användarovänliga grafiska användargränssnitt. Den senaste tiden har det varit brist på specialiserad personal inom hälsovårdsindustrin som har resulterat i ett beroende på dessa applikationer för att genomföra enkla uppgifter samt uppgifter på låg nivå. Alla dessa faktorer bidrar till det ökande behovet att hitta ett funktionellt sätt att kommunicera mellan robot och slutanvändare vilket tillåter expansionen av mobilmanipulatorapplikationer. Arbetet som beskrivs i denna avhandling adresserar problemet att finna ett intuitivt sätt att använda en mobilmanipulator i ett laboratoriemijö. Möjligheten att tillåta användaren att på ett enkelt och effektivt sätt arbeta med en manipulator via ett funtionellt grafiskt användargränssnitt analyseras. Innovationsvärdet och detta examensarbetes bidrag till nuvarande kunskap betraktar möjligheten att skapa ett modulärt gränssnitt baserat på användares behov. Detta möjliggör expansionen av mobilmanipulatörers applikation vilket ökar antalet möjliga användare. En förklarande forskningsstrategi används för att föreslå en grafisk användargränssnittsapplikation för att uppnå detta mål. Först användes data från ad hoc-undersökningar blandat med litteraturimplementeringar för att skapa den rätta applikationsdesignen. En iterativ implementering baserad på kodskapande samt tester användes sedan för att designa en värdefull lösning redo att testas. Slutligen presenteras resultat från en användarobservationsstudie med icke-robotikprogrammerare. De insamlade resultaten som samlades in under valideringsstadiet tack vare en grupp bestående av tio potentiella slutanvändare har analyserats genom användandet av en valideringsmatris som är baserad på tre parametrar. Detta demonstrerade hur systemet är både funktionellt och användarvänligt för nybörjare men också expressivt för experter.

Повний текст джерелаThe main objective of this thesis is to develop a control law to control a two arm robot in order to achieve the manipulation tasks and to ensure the safety aspects for the human and the robot. To accomplish this, we presented an overview of the studies that have been conducted in this context. Thereafter, we proceeded to the kinematic and dynamic robot modeling. In order to calculate its dynamic model, we used the SYMORO+ software. After giving a detailed presentation of the method for identifying the parameters of manipulator robots, we applied it in a concrete way on our own robot. This allowed us to obtain a vector of parameters able to ensure a positive defined inertia matrix for any robot joint configuration, as well as a good quality of torque reconstruction for both constant and variable joint speeds. Thanks to this dynamic identification, we were able to realize an accurate simulator of the robot on Matlab/Simulink. The external forces of the robot have been estimated from the identified dynamic modulus and an experimental validation has been described. To apply control laws on an industrial robot, it was necessary to think about an external communication on the robot. The adopted approach was presented as well as its realization on the robot. The latter allowed us to program in python all our problems to be implemented on the robot. After having validated all the steps previously mentioned we moved on to the implementation of the control on the robot. The main task we adopted is the stripping of the cables. For this purpose, we chose to implement a hybrid force/position control in which the external forces are controlled in order to guarantee the absence of damage on the cables to be stripped. The robot used to perform all the experiments is the IRB14000 YuMi robot from Abb. All the experiments performed in this project have been described and presented. This thesis work was carried out within the framework of the Robotix Academy project financed by the European regional development fund INTERREG V-A Grande Région

Повний текст джерелаThe work presented in this thesis focuses on the modeling and robust force control of flexible joints industrial robot manipulators used for FSW process. In order to reduce computation time and memory occupation, a novel interval-based approach for dynamic model simplification of industrial robots is proposed, which applies to arbitrary trajectories of whole robot workspace and contributes to obtaining negligible inertia parameters. Cases studies have been carried out on three kinds of test trajectories and torques analysis of robot dynamic equation, demonstrating the effectiveness and good performance of the simplification method. Then, the dynamic modeling and identification of robotic FSW process is performed, and the parameters of linear and nonlinear dynamic axial force process models are identified by using the plunge depth and its derivative. On the basis of the modeling of robotic FSW process which simultaneously considers the complete kinematics, the rigid robot displacement model, the joint flexibility and the dynamic axial force process model, a robust force controller can be obtained by using the frequency response approach. Besides, a simulator of robotic FSW process is developed and simulation results show good performance of the force controller. The oscillation of axial force in FSW process can be simulated when a disturbance model of initial vertical reference position is proposed and used in the simulation
