Abstract
An internal conduit vehicle comprises two coaxially aligned dual-vector wheels mounted to each end of a chassis. The wheels include multiple, elongated rollers each positioned at an angle around a hub assembly. Two motors mounted to opposite ends of the chassis are rotationally coupled to a hub assembly. A motor control system mounted to the chassis drives the motors so that the wheels counter-rotate with equal, but opposite torque, thereby driving the vehicle axially through a conduit.
