Abstract
An actuator that comprises a deformable material, an energy input part, and a characteristics change detection unit. The deformable material is configured with a polymer fiber and, by deforming in response to energy input from the outside, outputs motive power. The energy input part inputs energy to the deformable material. The characteristics change detection unit detects when the deformation characteristic of the deformable material has changed. The actuator also comprises a drive control unit that, by controlling the above-described energy, controls the output of the deformable material. When the characteristic change detection unit detects a change in the deformation characteristic, the drive control unit controls the energy in accordance with the change in the deformation characteristic.
