The sport of SumoBots has the same rules of sumo, but it is done with robots instead. In this project students work in engineering design teams and follow a structured process in the design and building of a robot that solves a given problem. To teach concepts related to gear ratios and mechanical advantage, students are asked to design their Sumo Bot to incorporate a compound gear train that increases the output torque. In the self-evaluation section, students are provided torque and speed val
