A self-propelled wheelchair with independently driven wheels and dual support frames connected in an articulating relationship. A front frame supports a seat and a rearward extended pivot connector. A pair of front wheels and left and right front drive units are connected to the front frame. A rear frame includes a forwardly extended pivot joint, a rear support platform having a power source thereon, and a pair of rear wheels and left and right rear drive units connected thereto. An articulating junction is formed by the front frame pivot connector attached to the rear frame pivot joint and providing articulation between the front frame and rear frame. A manually operable control unit includes computer circuitry in connection with each wheel drive unit, wherein manipulation of the control unit actuates each drive unit for control of rotational speed and direction of rotation for each wheel.
