## Summary

A competitor plans to design an Arduino autonomous robot for an upcoming sumo robot competition held on a non-magnetic dohyo, with rules limiting the robot to a weight of no more than 3 kg and length and width each no more than 20 cm, with no height limit. The robot will use a blade and sensors, and the competitor hopes to get advice on motor, battery, and blade selection to improve the chances of winning.
