The objective of this project is to design a dual speed drive train system for a robot that will compete in the FIRST robotics team competition. The success of a competition robot would be improved greatly by the capability to move at high speeds while still being able to deliver high torque. To accomplish this, a dual speed transmission system that will meet these requirements has been developed. Motor selection, gearing, clutch design and wheel selection are all critical elements involved in the success of the drive train. This report summarizes the four major subsystems that are required for the success of this project. The available motors, as supplied by FIRST, have been categorized and classified according to their usability for this project. The gearing of the transmission was analyzed for exact speed and torque requirements as well as for size and weight constraints. A fully functional clutch was designed to allow the controller to alternate between high speed and high torque modes using a linear actuator as the driving mechanism. Finally, extensive research and testing was conducted for wheel selection such that the coefficient of friction was large enough to avoid slippage and meet our torque requirements.
