Embedded Files
The possibilities are endless when building a Sumobot. All that you need is at least ONE LEGO® MINDSTORMS® Education EV3 Core Set. You can build the Sumo bot from scratch as long as it meets the robot design guidelines (see Sumo Bot Tournament Rules).
Building a Pre-Designed Sumo Bot:
If you or your students are EITHER new to the EV3 Mindstorm system OR have not previously built a Sumo Bot, then it might be a good idea for them to start by building a pre-designed robot.
Software Requirements: You will need to have the ability to read an Adobe PDF file: Adobe Reader Software.
Note: All instructions have been created using Lego Digital Designer and BluePrint software.

Every team should build at least one of these squares to help them make sure that their robot is within the size restrictions.
Use this model to help students understand how to build ramps onto one or more sides of their robot.

The Importance of Center of Gravity (COG)
This video shows how the location of a robot's COG has a significant impact on its ability to move, turn and push.

Using Gear Ratios to Improve the Power of the Claw
This video shows you how to build use gears to allow your Sumo Bot to lift the heavy opponent robot.
Building - Stabilization of Light Sensors.mp4Stabilizing Your Light Sensors
Stabilizing Your Light Sensors
During battle, your robot can tip forwards or backwards, causing the color sensors to falsely identify the board as being black or white. This video gives strategies for preventing this from happening.
Building - Fooling with Light Sensors.mp4Fooling With Your Opponent's Light Sensors
Fooling With Your Opponent's Light Sensors
This video describes strategies to fool your opponet robot into thinking that it is on the edge when it isn't, causing it to back away until it falls off the board.
Building a Sumo Bot with 4-Driving Motors
The EV3 system will allow 2 large and 2 small motors to operate at the same time. This allows for a Sumo Bot to operate using motors to control both the FRONT and BACK wheels. The following is a basic Sumo Bot that uses 4 motors in this way. The advanced programming page of this website explains how to program this robot.
