A robot toy includes a body and a controller. The body includes right and left arms, legs, arm-actuating mechanisms, thrust mechanisms, and a driving unit. The arms can be extended forward and back, and are pulled back by a predetermined biasing force in a normal condition. The arm-actuating mechanisms are provided at the respective arms and allow the corresponding arms to be extended and pulled back. The thrust mechanisms are provided at the respective legs and allow the corresponding legs to move forward. The driving unit drives one of a pair of the left arm-actuating mechanism and the left thrust mechanism and a pair of the right arm-actuating mechanism and the right thrust mechanism. The driving unit simultaneously drives the arm-actuating mechanism and the thrust mechanism in the same pair.
