Abstract
A movable and steerable device that has a platform with four wheel assemblies, any of which are both drivable and steerable. Different driving and steering options can make the device move in different directions and orientations. The driving can be done by a drive motor, forming a drive loop of material, such as chain, and a steering motor, also forming a steering loop. The different loops are attached to different sprockets on the device, which have different sizes, and therefore the different loops do not interfere with one another.
