Robot-sumo
From Wikipedia, the free encyclopedia
Robot-sumo or robo-sumo is a sport in which two robots attempt to push each other out of a circle (in a similar fashion to the sport of sumo).
The engineering challenges are for the robot to find its opponent (usually accomplished with infrared sensors) and to push it out of the flat arena. A robot should also avoid leaving the arena, usually by means of a sensor that detects the edge.
Robot-sumo is divided into classes, fought on progressively smaller arenas:
- Standard class robots may mass up to 3 kg and fit inside a 20 cm by 20 cm box, any height.
- Mini-sumo. Up to 500 g mass, 10 cm by 10 cm, any height.
- Micro-sumo. Up to 100 g mass, must fit in a 5 cm cube.
- Nano-sumo. Must fit in a 2.5 cm cube.
- Femto-sumo. Must fit inside a 1 cm cube.
Classes are further divided into remote-controlled and autonomous robots.
Sumo robots are built from scratch, from kits or from Lego components, particularly the Lego Mindstorms sets.
