Development of miniature cybernetic actuator driven by piezoelectric device

摘要

New types of miniature actuators so called cybernetic actuator for biomedical robotics are developed. The cybernetic actuator has four driving states: free, increasing, decreasing and lock. The state of free and lock provides safety characteristics for both human and mechanism by avoiding damage from overload. The rotary type and linear type of cybernetic actuators are designed and developed. Feasibility of both actuators is verified by experiments. Four driving states are confirmed and unique driving principle is verified successfully.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
