B-spline 곡선을 이용한 양팔 로봇의 궤적 계획

Abstract

This paper proposes an algorithm for the trajectory planning of a dual-arm robot. Since the original collision-free path obtained in a probabilistic manner is unnecessarily jerky, it may induce high acceleration in the robot’s actuators, so we regard this as a low-quality path. We propose a B-spline trajectory planning algorithm that transforms the path into a collision-free and smooth trajectory to improve its quality. We applied our proposed algorithm to a cell-phone assembly task using a dual-arm robot as a specific application example. The simulation results show that the smooth and collision-free trajectories can be generated for the task with our motion planning simulator.
