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 ...
