Testo completoThe variety of tasks in industry necessitates implementation of new manipulators. A behaviour analysis of these manipulators is necessary to compare their performances. The work presented in this thesis deals with the study of kinematical properties and of the performances comparison of two types of manipulators: 3-revolute (3R) serial orthogonal manipulators and 3-RPR planar parallel manipulators. First, a state of the art on important notions on kinematics and design of manipulators is presented. Then, in the 2nd section of this thesis, an exhaustive classification of 3R serial orthogonal manipulators with geometric simplifications is established. The classification criterion is the singularities topology in the workspace. Twenty-two different manipulators types are found. In the 3rd section, the twenty-two types are compared first according to the topology of their workspace, then according to a new performance index that we have introduced. In the 4th section, the singularities in the joint space of 3-RPR planar parallel manipulators are determined and analysed. An algorithm for the detection of cusp points is established. In the 5th section, two new forward kinematics degeneracy conditions for these manipulators are found. A new class of these manipulators is discovered: the degenerate manipulators. These degenerate manipulators have always a degenerate forward kinematic model and interesting kinematic properties. Finally, two methods for avoiding the singularities of the 3-RPR parallel manipulators are proposed: the planning of non singular assembly mode changing trajectories and the determination of maximal singularity free regions in the workspace and in the joint space of these manipulators. Results presented in this thesis can serve as an efficient help tool for the design of new manipulators
Safeea, Mohammad. "Des robots manipulateurs collaboratifs sûrs". Thesis, Paris, HESAM, 2020. http://www.theses.fr/2020HESAE036.
Testo completoCollaborative industrial manipulators are ushering a new era in flexible manufacturing, where robots and humans are allowed to coexist and work side by side. However, various challenges still persist in achieving full human robot collaboration on the factory floor. In this thesis two main challenges - safety and collaboration - for achieving that goal are addressed. On safety, the thesis presents a real-time collision avoidance method which allows the robot to adjust the offline generated paths of the industrial task in real-time for avoiding collisions with humans nearby. In addition, the thesis presented a new method for performing the reactive collision avoidance motion using second order Newton method which offers various advantages over the traditional methods in the literature. On collaboration, the thesis presents the precision hand-guiding as an alternative to the teach-pendant for performing precise positioning operations of the robot’s end-effector in a simple and intuitive manner. The thesis also presents new contributions into the mathematical formulation of robot dynamics, including a recursive algorithm for calculating the mass matrix of serially linked robots with a minimal second order cost, and a recursive algorithm for calculating Christoffel symbols efficiently. All the presented algorithms are validated either in simulation or in a real-world scenario

Testo completoA lower mobility parallel manipulator has less than six degrees of freedom and usually exhibits different motion types known as operation modes. Thus, it can be classified as reconfigurable on account of its ability to transition between different operation modes. This doctoral thesis mainly revolves around the kinematic analysis of some lower-mobility parallel manipulators, series-parallel manipulators obtained from their serial stacking and compliant mechanisms designed using their constraint singular configurations. Study's kinematic mapping is used to derive the algebraic constraint equations. They are further interpreted using algebraic geometry tools to perform mobility, kinematic and singularity analysis. Screw theory and line geometry techniques are used adjacent to algebraic approach wherever necessary

Testo completoWe address the problem of coordinating a dual arm robot using one or several cameras. After proposing an overview of the control techniques dedicated to this problem, we develop a formalism allowing to coordinate the motions of several arms thanks to multicameras image based visual servoing. Our approach allows to bene?t from the natural redundancy provided by the robotic system to take into account useful constraints such as joint limits and occlusions avoidance. We propose a strategy to deal with these tasks simultaneously. Finally, to make our control more robust with respect to image losses, we reconstruct the structure of the manipulated objects and the corresponding visual features. To validate our approach, we use the formalism to make the dual arm PR2 robot recap a pen. Simulations and experimental results are provided

Testo completodes robots constitués d'un bras manipulateur embarqué sur une plate-forme porteuse. L'objectif de
ce travail est de fournir un cadre méthodologique pour la synthèse de lois de commande par retour d'état de tels systèmes, en
partant du constat qu'une stratégie de coordination entre la plate-forme et le manipulateur requiert génériquement de commander la
situation complète de la plate-forme. L'originalité des deux nouvelles approches proposées est de permettre un contrôle coordonné
d'une tâche prioritaire de manipulation et d'une tâche secondaire de locomotion, obtenu via la stabilisation pratique
de la situation complète de la plate-forme le long d'une trajectoire de référence quelconque.
Ces deux méthodes génériques s'appuient sur la fusion de deux outils de commande:
l'approche par fonctions de tâches, dédiée au contrôle des bras manipulateurs, et
l'approche par fonctions transverses, consacrée à la commande des plate-formes non-holonomes.
Différentes applications de suivi de cible valident la flexibilité et la polyvalence de ces
approches de commande à travers le choix de plusieurs stratégies de coopération entre
manipulation et locomotion.

Testo completoUnlike industrial robot manipulators which are huge in size and of high price, many low-cost robot manipulators have already entered the market, with small size and light weight, this type of robots are more accessible to the public. However, limited by the cost, the components adopted (materials, actuators, controllers, etc.) are also limited, this often leads to less robust control performance. This thesis focuses on the controller design to improve the performance for such kind low-cost robot manipulators. To start with, for rigid case, dynamic modeling considering the actuator system is established, which forms a differential equation with constant parameters and disturbance, a method to identify the model parameters using observers and then an adaptive controller are proposed, simulation and experimental results are given. Then, in case of flexible joints, for simplicity, a single-link case model is considered. Firstly, link velocity measurement is assumed to provide link information, and an identification method and a two-stage adaptive control low are proposed provided that the static link position can also be measured, simulation result is given. Secondly, by using link acceleration measurement, an identification method and the same two-stage adaptive control low areproposed, this idea is generalized to identification and control of linear system using high-order derivative measurements, simulation result is presented. For implementation, inertial sensors (gyro and accelerometer) are used and experimental result is presented

Testo completoThis thesis is incorporated within the framework of the ANR ASSIST project. The aim of this project is to develop a two-arm manipulator robot to assist quadriplegic individuals in their daily lives. We are particularly interested in the arm control to perform manipulation tasks. In this context, a task consists of many steps: approaching the object, grasping, handling with one or both arms (opening a jar, for example), transferring to a human, dropping off, etc. Each stage requires a control system either in one of the following modes : position, force, vision, or in multiple modes at the same time. A control structure that can easily switch from one mode to another is necessary. In addition, the use of a hand for the manipulation instead of a simple gripper, requires a particular configuration of the hand to be set, depending on the shape of the object, and hence not only the position but also its orientation must be controlled. Different representations of the position and orientation of the end-effector of a manipulator in space were studied. Following this analysis, we developed a new control structure based on dual quaternions for simultaneously controlling the position and orientation of the end-effector. This solution is proposed in kinematic, dynamic and also vision-based control. Simulations and experiments on different robots allowed to validate these methods

Testo completoThis PhD thesis concerns the control of hybrid holonomic/ nonholonomic mobile manipulators, i. E. Robots composed of a manipulator arm mounted on a mobile platform. This work is devoted to the determination of a general framework for the feedback control of such systems. These control methodologies are based on the fact that a general strategy of motion coordination between the manipulator and the mobile platform requires to monitor the situation (position and orientation) of the platform. An original feature of the two approaches we propose is to allow a coordinated control of a priority manipulation task with a secondary locomotion task, obtained via the practical stabilization of the complete platform's situation along any reference trajectory. These two general methodologies rely on the fusion of two control tools: the task function approach, devoted to the control of manipulator arms, and the transverse functions approach, devoted to the control of nonholonomic platforms. Various application cases dealing with target tracking validate the flexibility and the polyvalence of these control approaches, through the choice of several strategies of cooperation between manipulation and locomotion subsystems

Testo completoIn recent years, the concept of Industry 4.0 has led to new possibilities of use for mobile manipulators (MMs) that are generally made of a manipulator arm mounted on a mobile base. The current Ph.D. is focused on the synthesis and control of new cooperative MMs by defining three challenges. The first challenge concerns the widening of the fields of application of robots. Therefore, we define a modular robotic system based on the use of multiple MMs (mono robots or m-bots) that can be used as a global system (poly-robot or p-bot) for collaborative tasks. The second challenge concerns the definition of the kinematic structure of the MMs. We propose a new generic method of structural synthesis that allows to obtain multiple kinematic architectures for m-bots that respect the constraints imposed by the task and the workspace. This method is based on structural analysis of MMs by the evaluation of the structural parameters (connectivity, mobility, redundancy and overconstraint). The last challenge concerns the modelling and control of the new architectures for the new fields of application. Two control laws (PID control and hybrid force-position control) are proposed in order to realise the considered task. Their validation is done with advanced simulations
Lopez, Damian Efrain. "Grasp planning for object manipulation by an autonomous robot". Toulouse, INSA, 2006. http://www.theses.fr/2006ISAT0009.
Testo completoThe autonomous robot performance in a dynamic environment requires advanced perception, action and decision capabilities. Interaction with the environment plays a key role for a robot and it is well illustrated in object and/or tool manipulation. Interaction with humans or others robots can consist in object exchanges. This thesis deals with object manipulation planning by an autonomous robot in human environments. A software architecture is proposed that is capable to solve such problems at the geometrical level. In general, a manipulation task starts by a grasp operation which quality influences strongly the success of the overall task. We propose a planner based on object inertial properties and an approximate convex decomposition. The whole mobile system taken into account in the planning process. The planner has been completely implemented as an extension of the planning tools developed at LAAS-CNRS. Its results have been tested in simulation and on a robotic platform. Object models may be known a priori or acquired on-line. Experiments have been carried out with a mobile manipulator equipped with a three fingers gripper, a wrist force sensor and a stereo camera system in order to validate the approach

Testo completoToday, robotic manipulators are being called upon to perform an increasingly wide range of tasks that extend beyond the conventional ones required in traditional applications. One such type of application is physical human-robot interaction. In order for such systems to be safe, it can be desirable to decrease their weight and strength by reducing the size of their actuators.Indeed, reducing the size of the actuators increases safety in two manners, the inertia of the manipulator decreases and the torques generated by the motors are greatly reduced. However, the main drawback of such manipulators is the reduction of their payload capacity.Therefore, better usage of the limited joint efforts is required to enable them to perform tasks that they would normally not be able to accomplish. Thus, this thesis presents a study of two main types of tasks where an effective trajectory optimisation strategy can be particularly valuable. The first task is that of lifting heavy objects, i.e., objects that exceed the conservative estimate of the payload capacity of a manipulator. Studying this task could lead to the design of lighter,more capable manipulators. This work focuses on studying trajectory generation methods to enable manipulators with relatively weak actuators to lift heavy payloads by fully utilizing their dynamics. The second task studied in this thesis is the task of throwing objects. Specifically, the distance throwing capabilities of manipulators is studied where the maximum distance that an object can be thrown with a given manipulator is sought. This task is studied at three levels of complexity: finding the maximum possible throwing capacity of manipulators with velocity constraints, finding the maximum throwing capacity considering a full trajectory with kinematic constraints, and finding the maximum throwing capacity considering a full trajectory with dynamic constraints. Finally, performance criteria are established from these two types of tasks in order help in the process of designing a new manipulator. Thus, a simple design optimisation simulation is performed as a proof of concept.

Testo completoThe aim of Inverse Kinematic transformation is to define joint motions around a configuration to obtain a desired end-effector trajectory, specified by operational coordinates. In Robotics we are interested in the performance of complex tasks industrial such as welding, assembly, or painting which all need the inverse kinmatic control. We present in this thesis efficient algorithms for solving the Inverse kinematic command used in any robot manipulator. The constraints of real time are harsly treated. The methodologes implemented take in account the position and speed aspects. In case of redundancy, the approach presented here assumed the motion of one link to be prescribed as an input and found the displacement of the rest of the mechanism as they incremented input. In fact this approach specifies an additionnal desirable trajectory which may allow an obstacle avoidance. Our programms are included by RCCL, "Robot Control under C library" which the real time advantages are well known. The singularity problem in relation to the redundancy is also analized
