Abstract
In a soft actuator having a cooler, a wearable robot having the soft actuator, a massage device having the soft actuator, and a method for controlling the soft actuator, the soft actuator includes a heat reaction member, a cooling part and a controller. The heat reaction member is configured to be contracted or relaxed according to a temperature change. The cooling part includes a cooling surface disposed at the heat reaction member, and a heating surface disposed opposite to the cooling surface. The controller is configured to control a power supply part so that a power is blocked to be supplied to the heat reaction member and the power is supplied to the cooling part, when the heat reaction member is changed to be a relaxation state.
