Abstract
A mobile base for robots or other devices requiring a transport mechanism is disclosed incorporating a plurality of wheels which are simultaneously driven and steered by separate drive sources so as to allow the mobile base to change direction without rotation of the mobile base. In an additional embodiment, each wheel is located on an extensible leg assembly which can be rotated to project outwardly from the mobile base and thereby provide additional stability to the base. This adaptive, retractable leg synchro-drive mobile base uses a third drive source to perform the extension and retraction of the leg assemblies and provides that the wheels maintain their orientation while extension or retraction occurs while the mobile base is in translation and that the wheel orientation returns to its previous state if retraction or extension occurs while the base is not in translation.
