Abstract
By analysing the formation mechanism of human facial expressions and summary of existing research about facial expression robot, the paper summarized the facial expression robot, developed three technical difficulties, and proposed the improvements according to the technical difficulties. Based on the above, the paper presented one facial robot with eight facial expressions of basic emotions. In mechanical part, the mechanical structure with 20 degrees of freedom is designed; in control part, SSC32 V2 is used to control 20 servo coordination movements; in simulation modelling part, a special silicon rubber material is developed and the soft part of material is used to as the skin of facial expression robot. The facial expression of robot substantially increased the extent of such robot simulation.
