A powered mobile lifting, gait training and omnidirectional rolling apparatus is for personal use by persons with complete loss of motor function in lower limbs for assisted walking in an upright position in desired direction of indoor and outdoor. All operations including bringing the apparatus to a user, ingress, walking around and egress are performed by users without assistance of other persons. The apparatus lifts the user from a floor, wheelchair or elevated surface, its overall size enables passing through narrow passageways, and omnidirectional wheels provide top maneuverability. Rotation of powered omnidirectional wheels is coordinated with motion of gait stimulation devices that drive user's feet, resulting in simulated walk. The apparatus comprises a rigid ‘U’-shaped base integrating a powered lifting and supporting device, powered gait simulation devices, step length setup devices, powered omnidirectional wheels with brakes, retractable support mechanisms, control, monitoring, communication and recording means, a power supply block, and a harness.
