论文摘要
强化学习方法作为一种有前途的技术在自由浮动太空机器人的运动计划中取得了卓越的成果。但是,由于计划维度的增加和系统动态耦合的加剧,双臂自由浮动太空机器人的运动计划仍然是一个开放的挑战。特别是,由于缺乏最终效果的姿势约束,当前的研究无法处理捕获非合作对象的任务。为了解决这个问题,我们提出了一种新型算法,即有效的算法,以促进基于RL的方法有效提高计划准确性。我们的核心贡献是通过先验知识指导构建混合政策,并引入无限规范以构建更合理的奖励功能。此外,我们的方法成功地捕获了具有不同旋转速度的旋转对象。
Reinforcement learning methods as a promising technique have achieved superior results in the motion planning of free-floating space robots. However, due to the increase in planning dimension and the intensification of system dynamics coupling, the motion planning of dual-arm free-floating space robots remains an open challenge. In particular, the current study cannot handle the task of capturing a non-cooperative object due to the lack of the pose constraint of the end-effectors. To address the problem, we propose a novel algorithm, EfficientLPT, to facilitate RL-based methods to improve planning accuracy efficiently. Our core contributions are constructing a mixed policy with prior knowledge guidance and introducing infinite norm to build a more reasonable reward function. Furthermore, our method successfully captures a rotating object with different spinning speeds.
