Robotic toy

DETAILED DESCRIPTION Therefore, in accordance with the objects and advantages listed above, and in achieving those objects, the present invention discloses a walking robotic toy which includes a radio-controlled electrically driven motor within a chassis, a transmission therein coupled to a drive wheel assembly, and at least two motor-driven middle legs and at least two pivotal corner legs, both being attached to drive mechanisms.
In one of the preferred embodiments, a robotic head is also included, said head having at least one servo motor attached to a gear assembly for activating movable components, such as teeth clenching, jaw pinching, head up-and-down movement, and head side-to-side movement.
Further, in the preferred embodiment, the invention includes a six-legged walking animatronic toy, powered by a rechargeable battery, and controlled via a radio-controlled transmitter and receiver pair.
Interchangeable outer body shells depicting various animals and insects may be clipped or easily attached to the top of the robot toy chassis.
These shells may be made of rigid plastic materials, or of soft rubber-like materials for depicting various animals, including dinosaurs and the like.
Furthermore, the shell may be a three-dimensionally blow-molded material having hard and soft portions for attachment and movement, wherein the hard portions may be attached to the chassis, while the soft portions may receive and cover mechanical components for depicting, for example, a dinosaur with a long neck.
The servo motors attached to the legs to engage and cause movement are controlled by a standard transmitter/receiver pair interfaced with control electronics.
The servo interface from the receiver includes inputs to a printed circuit board for controlling the individual motors attached to the various legs.
A printed circuit board receives input information from the first and second servo motors, and controls individual movements via pulse width modulation position signals.
Through this mechanism, the control electronics decode the servo signals and generate proportional direction control for the individual motors in communication with the various legs
