Abstract:
1. A wearable joint driving device comprising: a main frame attachable to a main part of a human body to surround the main part; a cylindrical rotatable frame connected to the main frame through a rotation mechanism to be rotatable in a bending direction of a joint portion of the human body, the rotatable frame being formed by a material having a predetermined rigidity; at least one fluid pressure actuator having an expansion/contraction member undergoing expansion/contraction through supply/discharge of a fluid and a covering net covering an outer periphery of the expansion/contraction member, end portions of the fluid pressure type actuator being connected to the main frame and the rotatable frame, the expansion/contraction member being reduced in length through expansion to thereby generate a driving force; and a control unit for controlling supply and discharge of the fluid to and from the fluid pressure actuator.
