Combinatorics and Sumo Robotics

Introduction

The sumo competition is very interesting, and in its most basic form is rather easy to conduct. Use some time to design and build the robots, then code it using a very simple line-detection algorithm in a loop, and finally have a tournament.

The mathematics is included into the combinatoric problem how to organize the competition.

Theory

Sumo Rules for Beginners

The simple Sumo code is easy but gives a lot of fun.

The field can be marked on a floor using black tape, or you might cut it from a plywood. The wooden field is better, because it is easier to note the winner.

You can attach some attacking tools to the robot, the more efficiently push the opponent from the field. The code shown here is very simple, and you need to adjust the parameters according to your robot.

Below is given three different methods to have a competition. Print the brackets and fill by hand.

Elimination

You cannot win if you lose.

Double Elimination

You cannot win if you lose twise.

All-Play--All
