Abstract: A locomotion system for use in a medical device, including at least one magnet, a rotor including a plurality of coil windings, and a ferromagnetic member. The rotor is configured, on application of a current to the plurality of coil windings, to travel along the ferromagnetic member and to impact on a surface.

Abstract: The present invention provides a robotic locomotive device that is capable of driving itself forwards and backwards, anchoring and steering itself whilst inside a tubular structure, for example, the human colon, or any structure comprising two opposing walls. In this respect, the device is made up of two or three segments covered in an elastic material and driven by an internal actuating mechanism. All of the segments have a concertina configuration that enable a shortening and lengthening motion. As well as contracting and extending in length, at least one of the end segments is capable of bending at an angle away from the longitudinal axis such that it becomes wedged or jammed between the walls of the tubular structure. That is, the end segments are capable of both a bending action and a contracting and extending action.

Abstract: The present invention provides a robotic locomotive device (1) that is capable of driving itself forwards and backwards, anchoring and steering itself whilst inside a tubular structure (200), for example, the human colon, or any structure comprising two opposing walls (202, 204). In this respect, the device is made up of two or three segments (102, 104, 106) covered in an elastic material and driven by an internal actuating mechanism. All of the segments (102, 104, 106) have a concertina configuration that enable a shortening and lengthening motion. As well as contracting and extending in length, at least one of the end segments (102, 106) is capable of bending at an angle away from the longitudinal axis such that it becomes wedged or jammed between the walls (202, 204) of the tubular structure (200). That is, the end segments (102, 106) are capable of both a bending action and a contracting and extending action.
