ABSTRACT:
An omni-directional vehicle (ODV) with a circular frame revolvably coupled to an appendage ring using a full circumferential coupling assembly. The appendage ring serves as a point of attachment for a push bar, trailer, tool, vehicle chassis, or other device. Two independent drive wheels located on an axis through the center of the frame are mounted at the same distance from a central vertical axis through the frame. Each wheel is powered independently and can rotate at variable speeds in either direction. The ODV is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The ODV can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground.
