Abstract:
A robotic toy to be operated by a radio-controlled transmitter, comprising:a main robot body chassis including at least one radio-controlled electric motor mounted in the chassis; at least two middle legs attached to the main robot body mid-chassis for movement, wherein the middle legs are moved by a drive wheel assembly through a transmission after receiving signals from a radio-controlled transmitter; at least two corner legs attached elsewhere on the robot body chassis; a drive gear attached to a drive shaft; a linkage drive arm in communication with the drive gear extending between one of the at least two middle legs and one of the at least two corner legs on the same side of the body chassis, such that when the electric motor is engaged, the drive wheel assembly translates motion through the drive shaft and the linkage drive arm to the middle legs and corner legs on either side; control electronics for receiving output from the radio-controlled transmitter, including a receiver output section and inputs to a printed circuit board, said electronics including a micro-control unit, a voltage regulator, a microprocessor and at least two H-bridge driver circuits for operating at least one of the middle legs attached to the body chassis and at least one of the corner legs attached to the same side of the body chassis; and computer software for operating the control electronics which then controls the movement of the legs attached to the chassis giving movement to the robotic toy.
