Conception et commande de robots parallèles volants

Abstract : Aerial manipulation is one of the challenges of robotics over the last decade. One of the constraints on the development of aerial manipulators is the limited autonomy of drones, reduced by the load and energy consumption of the on-board manipulator. One way to overcome this limit is to have several drones collaborate on a manipulation task. This thesis deals with the design and control of a new type of autonomous aerial vehicle for manipulation tasks. The concept consists in the collaboration of several drones, in particular quadrotors, through a polyarticulated passive architecture. The robot thus obtained is a fusion between the passive architecture of a parallel robot and several drones. The study of the dynamic model of this robot class highlights a decoupling in the dynamic model. This decoupling allows the design of a cascade control law. This controller provides stabilization and trajectory tracking for these robots. Two study cases are then presented in this thesis: a flying parallel robot with two drones and a flying parallel robot with three drones. For these two robots, a numerical simulation is performed to validate the controller performances. These simulations also allowed to validate the reconfiguration abilities of passive architecture in flight. The work was successfully carried to the experimental stage for the flying robot with two drones.
