Full textThis document introduces an approach to the design of robot workstations based on the intrinsic and extrinsic task constraints. It presents our reflexions concerning the off-line "preadaptation" function through physical configuration of the workstation. We show that (equi-probability) Chyper)ellipsoids having (of) equi-probability of pose or compliance result from the structured parameters and the joint properties of a robot. From these two ellipsoïdale envelopes, we define a robottask conformity index that expresses its adequecy for jointpostures. He also introduce the utilization of the robot's natural (anisotropie), generally considered as a handicap. A representation madel will give the limits of the domaine for which the robot possesses the required charecteristics to execute the task, i. E. The joint limits not to surpasse for task adaptability. For an isolated task, the direct kinematics of the inverted structure is used to exploit this representation madel. However, production often takes place in a multi-tasking context. Here, apart from the constraints specifie to the tasks, new inter-task constraintes in the space of large solid body motions are imposed depending upon the relative situations of the tasks. We propose two solutions to the design of an adapted robot localization in a multi-tasking environment of rigidly predetermined tasks. New definitions are introduced to this end. They provide practical means to apply the standardized concept of a useful workspace

Full textGross motions programming is an obligatory step for task planning in Robotics. This thesis comprises the conception and the implementation of a path planning module with obstacle avoidance, applicable to an assembly robot of an open mechanical chain, susceptible to be integrated in a robot programming language. The obstacles present in the work space of the robot are transformed into prohibited volumes in the N-dimensional joint space where the configuration of the robot is represented by a point. A recursive algorithm performing this transformation is presented. According to the number of the robot joints and to the state of encumbrance of the robot's environment, the choice between the simplified solution and the general solution is proposed, the simplified one allowing reduction of the computational burden for path planning. In case of a six-jointed robot working in a relatively clear environment, the simplified solution which approximates the last three joints of the robot by a sphere is analysed. The path generated for the simplified robot is collision-free for the whole six-joint robot. When the robot works in a cumbersome environment where it is impossible to find a collision-free path for the simplified robot or in the case of a redundant robot, the general solution which decomposes the joint space in a set of three-dimensional sub-spaces is analysed. One obtains thus, in a systematic manner, a collision-free path for the whole robot

Full textAmongst manufacturing tasks, assembly operations seem to be the most ticklish to robotize. The first part of this dissertation presents general considerations on that problem and gives the state of the art on the subject, under a classification form, which we wanted as systematic as possible and the most exhaustive. These considerations lead us to conceive a n original passive compliant device, provided with two rotations centres, which we called "DCR-LAI system". The second part of our thesis i s devoted to the description of that compliant structure and its working principles. We also give some experimental results related to measures of constraints appearing during a given example of insertion. The analysis of these results allows us to verify our hypothesis, and shows the working particularities of our device. The last part of our thesis gives a mathematical model of geometrical and dynamical behaviour of our compliant structure, which permits the simulation , of the evolution of contact constraints between pin and bore during insertion. Such a simulation may be used as a decision and for the choice of a compliant device with regards to characteristics of parts to assemble
