Claim:
1. A medical apparatus comprising: a self-contained, transparent toroidal device comprising an inner device surface and an outer device surface, the inner and outer device surfaces comprising inner walls and outer walls configured to form a toroid, where a portion of the outer walls associated with the inner device surface are adjacent to each other and are configured to form a channel, and where another portion of the outer walls associated with the outer device surface are configured to contact an external wall; and an internal propelling mechanism located entirely within the inner walls of the transparent toroidal device and configured for inverting the inner device surface and outer device surface, with the inversion safely propelling the apparatus without sliding of the outer device surface against any contacted external wall and allowing low friction movement of the apparatus with rotation of the toroidal device, the internal propelling mechanism comprising: a controller, a structural frame with a plurality of rollers disposed thereon, and at least one motor, wherein the controller instructs the motor to rotate the plurality of rollers to cause the inversion of the inner device surface and the outer device surface, with the inversion propelling the apparatus forward or backward without sliding the outer device surface against any contacted external wall.
