Contour control of a robot arm is an act the end-effector tip being moved along reference Cartesian path, with assigned velocity. When torque saturation occurs, and lasts for some time, contour deteriorations result. In addition, system delay dynamics also causes deteriorations. this paper, offline trajectory generation algorithm described, which achieves both optimum avoidance compensation.
This paper analyzes the performance of an Extended Kalman Filter (EKF) based attitude estimator for a Quad Rotor Unmanned Aerial Vehicle (QRUAV).
