A device fashioned in the shape of a toroid is rotated by a mechanism that propels itself in one or more directions based on internal rotation. In one specific example, the toroidal device is a toroidal balloon, where the tread of the toroidal balloon driven vehicle (TBDV) is self-contained and the entire outer surface is dynamic. Such a device is uniquely and ideally suitable for exploration of a tubular structure such as, but not limited to, the alimentary tract.
