Coudurier, Mathieu. "Amélioration de la précision des robots industriels." Chambéry, 2003. http://www.theses.fr/2003CHAMS003.
Full textThe study begins with a state of art on the static accuracy of six-axis industrial robots, then exposes the various inaccuracy sources, as well as the techniques usually planned to correct them. The strategy used to improve the accuracy is then described and it consists in two calibraton techniques performed off-line and then in-line. The first procedure identifies the most significant defects of the robot, while the second aims at compensating periodically for the drifts of the model. The study then deals with the various defects present in the transmissions, and with their compensation based on the instrumentation of the gear box. Finally, experimental results show the validity of the described techniques, as well as their interest for flexible measuring applications

Full textThis thesis is part of a national project named SRDViand whose aim was to develop a robotic system for the deboning and cutting of animals meat. To determine the cut paths, a structured light system has been developed. It refers to vision systems that use light projection models for 3D reconstruction tasks. To achieve best results, the definition of a new calibration method for structured light systems was established . Based on a large state of the art and also with a proposed classification of these methods, it has been proposed to calibrate a camera projector pair using visual servoing . The validity and the results of this method were tested on the basis of numerous experimental tests conducted under the SRDViand project. Following the development of this method, a prototype bovine cutting was performed

Full textThis thesis covers the modeling and robust control of cable-driven parallel robots (CDPRs) for two industrial applications for the naval sector: pick and place of metal plates (ROMP) using a suspended CDPR, and window cleaning (ROWC) by a fully constrained CDPR. The work was carried out in the context of the ROCKET project at IRT Jules Verne. The first part of this thesis focuses on the modeling and calibration of CDPRs. Models are written, including the consideration of pulleys geometry and cable elasticity. A linear model of cable elasticity introduced and used to write the robot stiffness matrix. A method for estimating the platform mass and center of mass position is proposed and experimented based on cable tension measurements, assuming a low-dynamic trajectory. Finally, the calibration of CDPRs is discussed and an automatic calibration method is tested in simulation based on the different models. The second part is dedicated to the robust control of RPCs against the perturbations identified for both applications. Several control architectures have been experimented depending on the available information about the system. Two families of controllers are compared for the control of ROMP: a proportional-derivative (PD) controller and a recent controller automatically balancing between sliding mode or linear algorithms (SML). In the case of fully constrained CDPRs such as ROWC, the control architecture must include a tension distribution to ensure safety. A new tension selection criterion based on the stiffness matrix is proposed to reduce the displacement of the platform due to water jet pressure. Finally, CDPR emergency stops are discussed and the behavior of ROMP and ROWC prototypes was evaluated in emergency situations
