Abstract: This invention features a mobile robot having a body which has an azimuthal angle that is optimally fixed in space and provides the basic reference for the robot to the outside world. The robot further includes a drive system having wheels for enabling movement of the robot, a synchronous steering mechanism which turns the wheels independently of the body, and a head which turns with the wheels. The robot further includes memory for storing the azimuthal angle of the body, a detector assembly disposed in the head for sensing a navigation beacon and resolving an angular deviation between the head and the beacon, and an element for incrementing the stored azimuthal angle by that angular deviation. A system for enabling orientation adjustment is also disclosed.
