Holonomic Spherical Mobile Robot : Omnidirectional spherical body robot using wireless control

Abstract: The purpose of this project was to construct a holonomic mobile robot driven with omni wheels. That would enable movement in all degrees of freedom. The finished product was a robot platform within a spherical shell body controlled by input commands defining speed and direction from a wireless communication medium. The platform was iteratively designed and constructed with parts made out of laser cut acrylic plastic. By using omni wheels powered by Direct Current (DC) motors, which will be described further, the holonomic drive could be realized as the wheel hubs were placed on the platform with calculated angles.
