- Abstract:
-
In order to promote the natural and harmonious communication between robots and human beings, and to realize human-computer interaction, a system for a humanoid robot head with facial expressions is developed. It mainly includes a humanoid robot head movement mechanism and a control system. The humanoid robot head has 22 degrees of freedom, including the eyebrows push-pull mechanism, eye mechanism, jaw mechanism and neck mechanism. FPGA is used as the servo controller, the control interface is designed in LabVIEW, and the control system of facial expressions is developed. The eight basic expressions and corresponding best displacement loads are obtained through simulations of facial expressions. It is found that the implementation of facial expression relates to the loads on the skin of face, the region size and the position of the load applying in the process of simulations. The experimental results show that the robot is able to realistically reproduce the eight basic expressions.
