摘 要: This paper presents a control system for redundant robot manipulators that handles the path planning and redundancy control in two separate loops. The goal is to simplify industrial programming of redundant robots, by decomosing it to a familiar path planning loop, and an autonomous redundant control loop. The familiar path planning is done using an industrial robots native control system, which is already known to the operator. An external feedback loop acts as a secondary task control loop so that the redundancy in the robot is used automatically. The secondary task control is expanded from the null space projection method to a method where a parallel space to task space is modeled in joint space. The system was implemented and experimentally verified on a NACHI MR20 7-axes industrial robot with AX20 Controller. The secondary task in the experiments was an obstacle avoidance task that was tested in unknown dynamic and static environments.

本文提出了一种冗余机器人控制系统的方案,通过两个独立的回路分别处理路径规划和冗余控制。其目标是简化冗余机器人的工业编程,将复杂任务分解为一个熟悉的路径规划回路和一个自主的冗余控制回路。熟悉的路径规划采用工业机器人原生的控制系统,该系统对操作员而言已十分熟悉。外部反馈回路作为辅助任务控制回路,使机器人冗余度能够自动发挥作用。辅助任务控制从零空间投影方法扩展为在关节空间中建模任务空间的并行空间的方法。该系统已在配备AX20控制器的NACHI MR20七轴工业机器人上实现,并通过实验验证。实验中的辅助任务为避障任务,测试环境包括未知的动态与静态场景。
