Compliance control of a humanoid arm based on force feedback

摘要

Humanoid robots are expected to take an important role in human daily environments such as offices, homes and hospitals. The flexibility of the humanoid motion is a fundamental requirement for human-robot interaction. In this paper, a compliance control for humanoid grasping objects is proposed. The force/torque of the end-effector is measured by a 6-axis force sensor located at the wrist. Using the proposed method, it is possible for the humanoid robot to grasp the object with a small interference force and keeping the desired hand's posture. The effectiveness of the proposed method is illustrated through the experiment of object grasping.
