How to replace the cumbersome and complicated program operation in the past through more natural human-computer interaction for the Following Robot. In this paper, Xtion Pro Live Somatosensory devices is introduced into the robot control system, and designed a kind of Following Robot based on bone identification. The full paper analyzes the overall design composition of the Following Robot and conducts experimental analysis. The results show that: On the basis of realizing target following, this robot can also recognize and execute target action, which greatly improves the maneuverability of the robot.
