The vehicle is comprised of a chassis supporting a magnetic drive wheel for driving and steering the vehicle and a stabilization mechanism. The magnetic wheel comprises two flux concentrator yokes and an axially magnetized hub extending therebetween. The hub includes a central housing configured to house a sensor probe and enhance the magnetic pull force of the wheel by providing a continuous pathway of high magnetic peiineability material for magnetic flux to flow axially through the drive wheel. The stabilization mechanism comprises a front and rear facing support element moveably coupled to the chassis and configured to contact the surface and move symmetrically relative to the chassis thereby maintaining the vehicle and probe noiinal to the surface and providing stability to the vehicle while traversing surfaces regardless of surface curvature and vehicle orientation.
