Traditional robotic arm path planning methods are mainly carried out in the tool center point operation space, and frequently solve inverse kinematics problems, thus consuming a large number of computational resources. In contrast, using positive kinematics for planning in the joint space not only improves the efficiency, but its analytic solution also has higher accuracy. In order to better cover the environmental state space, this paper adopts the full-preserving experience preservation approach. In order to realize fast and efficient sampling of high reward value experience, this study constructs an innovative hierarchical memory structure and eliminates the overfitting phenomenon that may be caused by biased sampling through the Bias-Free strategy. Experimentally validated in the continuous path planning task of a textile robot arm, the proposed hierarchical memory deep deterministic gradient strategy method (HM-DDPG) demonstrates excellent performance and practicality in the textile robot arm path planning problem.
