NXT Mini Sumo Bot Fun Projects for your LEGO ® MINDSTORMS ® NXT! Mini Sumo Bot:: In a robot Sumo match, two robots start inside a ring marked with a border of a contrasting color and try to be the first one to push the other robot outside the ring (without accidentally driving outside the ring themselves). There are a large variety of mechanical designs and programs that could be used, but most robots start with a light sensor to detect the border of the ring. Here is a simple robot and a very simple program to get you started.

You can use the Test Pad that came with your NXT set as a Sumo ring, or mark out your own ring with black electrical tape on a light colored surface. If you don't have another NXT robot to go up against in your Sumo match (or while testing and preparing for your match), you can build various dummy robots and other objects to try to push. Can your robot push all of the objects outside of the ring before accidentally driving outside the ring itself? Copyright © 2007-2011 by Dave Parker.

This LEGO MINDTORMS EV3 Sumo Bot uses three EV3 Large Motors, two of which have “triple torque” due to gearing. In the false-colored picture, the pink 12-tooth gear that is directly connected to the EV3 Large Motor touches the turquoise 36-tooth gear. This “gearing down” increases its torque three times, for increased pushing power. The center motor operates the yellow “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 for SuGObot competitions. Designed by: David Luders • Instructions. This Sumo Bot can be built using the LEGO Mindstorms EV3 31313 retail set’s parts. It features a front flipper, wide rubber tires for good traction, and the EV3 Infrared Sensor for manual operation via the EV3 Remote Control.

As an option, the pair of red 2L Technic Axles allow for mounting the Mindsensors “Sumo Eyes” to run the SuGObot program. Designed by: David Luders • Instructions.
