Abstract

Disclosed is a high speed actuator. The high speed actuator includes an actuation part configured to cause deformation such as bending or twisting and an active stiffness controller on a surface of the actuation part or in the actuation part configured to control in real time a stiffness (e.g., of the actuator) according to an external signal. The active stiffness controller may control a stiffness of the high speed actuator in order for the actuator to be actuated at a high speed. Moreover, since the stiffness of the actuator is controlled in real time, a speed of the actuator may be controlled in real time.
