Force-Supported Human-Robot Collaborative Handling Technology Using Integral Reinforcement Learning
IIn daily practice,humans frequently transfer and handle heavy objects.Moving heavy items to target positions can be item-consuming and require significant manpower.With the increasing use of collaborative robots(Cobots),the Cobots can serve as human colleagues in a natural and efficient manner to work together seamlessly to complete the simple,time-consuming and labor-intensive tasks,just as humans working together.To address the low positioning accuracy and high interaction force,this paper proposes an integral reinforcement learning-based method for force-supported human-robot collaborative handling.The dynamic model of human-robot collaboration is used to analyze the entire handling process.Mathematical models for the inner and outer loops of collaborative handling are put forward,and integral reinforcement learning and adaptive impedance control are integrated to establish a method for collaborative handling between humans and robots.Experimental verification is conducted to show that this method meets daily handling requirements.The results of the human-robot collaborative handling experiment show that the proposed method is effective.
