The present application relates to a kind of
variable stiffness fiber reinforced programmable
soft actuator unit, including flexible matrix and controllable module, flexible matrix is pipeline-like, and controllable module is fixed on the outer layer of flexible matrix distribution;Controllable module uses single-layer module or the multi-layer module arranged inside and outside;Each layer of controllable module is wound by at least one
variable stiffness fiber according to certain angle and direction;The
control line of connection controllable module is distributed in the inner cavity of flexible matrix, and is connected with external
control system;The two ends of the inner cavity of flexible matrix are blocked and leave medium filling and discharging mouth, and fluid medium is filled in the inner cavity;Controllable module state is two kinds of flexible state and rigid state, when carrying out the
deformation control of
soft actuator unit, by controlling part
variable stiffness fiber to be rigid state, another part variable stiffness fiber is flexible state, realizes the
deformation control of
soft actuator unit.
