In this paper, an adaptive trajectory tracking controller for quadrotor MAVs is presented. The controller exploits the common assumption of a faster orientation dynamics w.r.t. the translational one, and is able to asymptotically compensate for parametric uncertainties (e.g., displaced center of mass), as well as external disturbances (e.g., wind). The good(More)
The paper presents an adaptive control for an aerial vehicle equipped with a manipulator, the latter is assumed to be already driven by a joint-based controller. The proposed control generates the vehicle thrusts by properly taking into account the physical interaction with the arm. Being adaptive, it estimates and then compensates the dynamics of the whole(More)
The low level control for an underwater vehicle equipped with a manipulator is addressed in this paper. The end-effector trajectory is assumed to be properly inverted into vehicle and joint desired trajectories to be sent to the respective low level controllers. Off-the-shelf manipulators are often equipped with low level position or velocity joint control(More)
In this paper an underwater vehicle-manipulator system is considered in order to accomplish two operations, namely to turn a valve and to push a button. Realistic assumptions, such as imperfect knowledge of the environment, have been considered with the purpose to design the proper interaction control scheme. In addition, due to the poor knowledge of the(More)
In this paper a three layer control architecture for multiple aerial robotic manipulators is presented. The top layer, on the basis of the desired mission, determines the end-effector desired trajectory for each manipulator, while the middle layer is in charge of computing the motion references in order to track such end-effectors trajectories coming from(More)
In this paper, an impedance control scheme for aerial robotic manipulators is proposed, with the aim of reducing the end-effector interaction forces with the environment. The proposed control has a multi-level architecture, in detail the outer loop is composed by a trajectory generator and an impedance filter that modifies the trajectory to achieve a(More)
