ABSTRACT:
A robotic joint for use in toys or other robotic assemblies to provide locomotion to animated figures, sub-assemblies, and toy construction building sets. The robotic joint is particularly adaptable because one side of the joint carries the motor that is powering the joint. It also provides for four-way action in a joint in a very compact space by attaching a motorized joint directly to the shaft of another motor. It can also provide omni-directional action in a joint, since each motor turns the shaft or turns the motor housing based on the amount of resistance applied to the shaft. This can be demonstrated in a joint that is used to support a leg in which the joint has two motors attached by their shafts, perpendicular to each other in the same joint. A joint structure is provided in which two parallelograms are placed substantially perpendicular to one another to distribute the weight.
