AI Technical Summary
Technical Problem
The facial structure of existing bionic robots has the problem of being too mechanical and lacking realism during expression switching.
Method used
A method for switching expressions is provided. By calculating the embedding displacement of the current expression and the target expression, it is determined whether a direct switch is possible. If not, a transition expression sequence is generated, and the embedding is controlled to move according to the transition expression sequence to smoothly switch to the target expression.
Benefits of technology
It reduces the mechanical feel during expression switching, and improves the realism of the facial structure and usability.

Abstract
The invention relates to the technical field of bionic robots, and particularly discloses an expression switching method, a face structure and a bionic robot. The expression switching method comprises the steps of receiving an expression switching instruction, obtaining displacement A1 of all inserts 20 of a current expression and displacement A2 of all inserts 20 of a target expression, and judging whether the current expression can be directly switched to the target expression or not based on A1 and A2; if not, a transition expression sequence for switching the current expression to the target expression is obtained based on A1 and A2, and the transition expression sequence comprises at least one intermediate expression; and under the current expression, controlling each insert 20 to move according to the transition expression sequence until the target expression is switched. According to the expression switching method, the mechanical feeling generated by switching the current expression to the target expression can be avoided, and then the sense of reality of the face structure in the expression switching process is improved.
