EV3 Triple-Torque Battlebot




This Lego Mindstorms EV3 battlebot uses three EV3 Large Motors, two of which have "triple torque" due to gearing. The 12-tooth gears (directly connected to the EV3 Large Motor) touch the 36-tooth gear (connected to the wheels). This "gearing down" increases its torque three times. The center motor operates the "flipper" arms for upending opposing robots in a Lego Sumo or Battlebot competition. Parts from the EV3 45544 Education Set are supplemented by the third motor and EV3 Color Sensor (for detecting the edge of a Lego Sumo arena). You can use your spare parts to make the flipper larger; with it in the "up" position, it measures ~7"x7" (~22x22 studs). The EV3 Ultrasonic Sensor detects the opposing robot, or it can be replaced by a Mindsensors "Sumo Eyes" sensor ( www.mindsensors.com/ev3-and-nxt/28-dual-range-triple-zone... ) for SuGObot (www.sugobot.com ) competitions.
