AbstractAs the growth of technology in electronics, controllers and mechanical engineering, designing robots in various forms becomes very interesting. Self-balancing and driving robots such as cars, bicycles, quad-rotators, aero-planes, ships and underwater vehicles have been various interesting forms of vehicle-like robots. Robot vehicle have been designed to adapt many kinds of environmental and geometry condition, and applications. They are designed to perform smartly in different ways by aids of many sensors, fine actuators and well developed control algorithms. In my thesis, a sphere shaped robot vehicle which drives by rolling omni-directionally its entire sphere body is developed and controlled its geo position on the earth. The GPS attached in robot controller receive the position of robot from nearby satellites. The digital compass sense the heading direction of robot. When user send a new geo position from computer through XBee wireless, the robot calculates for distance, different in angles and behavior for individual wheel moments inside the sphere. Their overall calculated moments result the CG (Center of Gravity) of robot to shift to direction of new geo position, thus the outer sphere will have to follow to its CG to keep in center, until the robot location meet with user commanded location.
