This paper described about practical evaluation and functional design of small self-control mobile robot. A new architecture for controlling small mobile robots with a GPS and an Electronic Compass is described. We designed and developed small self-control robot with simple computational machine for future Mars investigation rover. Many trial tests for practical requirements were proceeded for each elements of body structures, electric circuits and software programs. The result using small rocket laden a mobile robot was verified durability of body design and reliability of robot control system.
