Claim Text:
1. A mobility aid comprising: a. a frame, at least one handle, a motor, and a plurality of wheels; b. a proximity sensor to generate data indicative of the proximity of said mobility aid to a user; c. circuitry coupled with said proximity sensor to determine whether said data generated by said proximity sensor indicates that said mobility aid is within a given distance from a user of said mobility aid; d. a force sensor coupled with said at least one handle to determine whether said user is in physical contact with said at least one handle; and e. circuitry coupled with said force sensor and at least one of said plurality of wheels, wherein said circuitry immobilizes said wheel when said user is in physical contact with said at least one handle; and f. said circuitry coupled with said proximity sensor is also coupled with said motor, said motor is coupled with at least one of said plurality of wheels, and said circuitry causes said motor to alter the movement of said wheel in response to data from said proximity sensor such that said mobility aid is adapted to move in order to maintain a position proximate to said user when said user is in motion and is not in physical contact with said mobility aid.
