Mini Sumo Robot

A simple and compact Mini Sumo robot designed for sumo robot competitions. The robot uses two DC gear motors and the Cytron Maker Mini Sumo Controller as the main control board.

Components

  • 2× plastic DC gear motors

  • 2× HC-SR04 ultrasonic sensors

  • 1× Cytron Maker Mini Sumo Controller

  • Wheels compatible with the motor shafts

  • LiPo battery

  • Optional razor blade for the front

  • M3 screws for mounting the controller and attaching the front blade/scoop to the frame

Sensor Mounting

The HC-SR04 sensors can be mounted in two ways:

  • Double-sided tape or glue for a simple and quick installation

  • M1 screws for a more secure and removable mounting

The sensor mounts are designed to allow both options.

Controller Mounting

The Cytron Maker Mini Sumo Controller can be screwed directly to the frame using M3 screws.

Front Scoop

The front scoop can be attached to the robot frame using M3 screws. This provides a secure connection while still allowing the scoop to be removed or replaced.

Razor Blade

A razor blade can be attached to the front of the robot. It can be glued directly to the front scoop. The blade helps create a low front edge for getting underneath the opponent.

Assembly

The main body is 3D printed and designed to hold the motors, electronics and sensors in a compact configuration. Depending on the motors and battery you use, some small adjustments may be necessary.

This model is intended as a base for building a Mini Sumo robot and can be modified or adapted to your own electronics and components.
