PROBLEM TO BE SOLVED: To provide a robot toy, which is actuated without need of an external power supply or complicated control by using a connector provided on an electronic device such as a personal computer to carry out both power feeding and signal transmission. SOLUTION: In a robot part, an actuator using shape memory alloy is used for controlling power supply fed from the electronic device based on a control signal transmitted together, so that current through the shape memory alloy is controlled for simply controlling its action.
