A manufacturing system has a material handling system that uses free roaming mobile apparatuses that are under the control of a visual navigation system that has the capability of regenerating images that are temporarily obstructed from view of a visual navigation system. The visual navigation system uses the images to provide commands that navigate an electrical controllable apparatus such as a mobile robot. The mobile robot is fitted with a minimum of three navigation beacons which emit a light visible to overhead television cameras. The beacon area is arranged so as to form a triangle. The shape and dimension of the triangular pattern is measured and stored in a memory unit within the visual navigation system. When a beacon is blocked from view of the television cameras, the visual navigation will regenerate coordinate of the blocked beacon and provide the necessary navigation commands to the mobile apparatus.
