WebTask Space Trajectory Planning for Robot Manipulators to Follow 3-D Curved Contours. A trajectory planning based on the Catmull–Rom spline is proposed to allow a robot to move via several points in a task space and show that the robot can follow the 3-D curved contour in uniform speed using the proposed method. WebJun 7, 2024 · This paper proposes an algorithm for trajectory planning of dual-arm robot. Since the original collision-free path obtained in a probabilistic way is unnecessarily jerky, it may induce a high acceleration to robot’s actuator so we regard this as a low quality path. To improve the quality of path, we propose the B-spline trajectory planning ...
