A powered omni-directional security, patrol and surveillance vehicle that includes a circular frame and two drive wheels capable of independent powered forward and rearward rotation about a horizontal axis. The drive wheels are adapted to allow the vehicle to spin in place about a vertical axis which intersects the horizontal axis midway between the drive wheels and which is generally centered in the circular frame. An observation platform including an operators control station is mounted to the frame on a lift such that it is capable of selective elevation for superior vantage points. A cab preferably encloses the operator's station. A plurality of swivel casters disposed on distal ends of telescopic outrigger arms are circumpositioned about the circular frame.
