Concept In his senior year of high school, Rich took an
engineering class that required a senior project. Rich enlisted two friends to build a 75 pound autonomous sumo to compete in the National Robotics Challenge for 2004. A proposal was made to the Explorer Post for funding.
Since Flaming P'nut was built with over 100 pounds of steel, switching to aluminum while keeping the same drive train/control/sensors was the basic configuration.
More speed would be a major improvement so it was decided to use two 12 Volt batteries to improve the speed from the sedate 32 inches per second of the 150 pound sumo. Many previous attempts to build a MOSFET control over 20 Volts resulted in a haze of magic smoke in the Brooks household. Fortunately, Roboteq had introduced a new, fully featured, serial driven motor control for a very little more money than the 72 MOSFETs in in Flaming P'nut. A quick review of the Roboteq data revealed a control structure that was well within the capabilities of high school students programming the Basic Stamp. |
