SphereBot is a project I created as a part of the VizProto (3D Visualization and Rapid Prototyping) class at Arizona State University.  The robot moves using two orthogonally positioned modified servo motors.  The motors are driven from a computer via Bluetooth communication.   This section shows the original parts which were printed on a 3D printer, silicon molds created to cast finished parts, electronics and motors and other fabrication details.
