Abstract
A robot-like toy vehicle is provided, including: a self-propelled base having a power source; a housing for reciprocally rotating relative to the base; a pair of arms mounted on opposite sides of the housing for swinging movement; a support attached to the base within the housing; a head mounted on the support for inclining and returning movement; an elevation member mounted for upward and downward movement along the support to incline and return the head; a rotary lever for raising and lowering the elevation member; and a cam for rotating the rotary lever. During operation, the housing of the toy vehicle rotates while the left and right arms swing so as to represent playful walking. In addition, the cam moves to rotate the rotary lever so as to raise and lower the elevation member and incline and return the head so as to represent the robot-like toy vehicle hanging or nodding its head. A microphone is mounted on the toy for sensing an external sound to change the movement of the toy via an electrical control circuit.
