摘要
To synchronize motions between the robot and human, we propose a control algorithm for physical humanrobot interaction (pHRI), based on the multi-joint neural oscillator. The input of the algorithm is the joint-torque signal of pHRI, and its output is the expected-angle of the robot joint. Coupling characteristics are analyzed for representative two-joint neural oscillator. Based on the robot arm, experiment is implemented for human-robot handshaking by using this algorithm. The experiment results indicate the algorithm validity. The control algorithm can realize the synchronization of motions between robot and human. The strength of input-output synchronization can be varied by adjusting the gain parameters in the algorithm. ©, 2015, South China University of Technology. All right reserved.
