My high school robotics team is working on something similar with Raspberry Pi's. There is not much documentation but you can check out the code here: <a href="https://github.com/InspireRobotics/sumobots" rel="nofollow">https://github.com/InspireRobotics/sumobots</a>
This is pretty cool for teaching Arduino, but most fighting robot builders on a budget use HobbyKing/Turnigy remote control systems. These are purpose built for this kind of thing, quite reliable, and cheap, especially if you wait for a sale.
Wow what a terrible website. The GDPR advertising opt-out:<p>1) Renders at the top of the page when the page is loaded, then because this link contains an anchor scrolls you to that anchor, while the entire screen is greyed out<p>2) Your behavior is actively being tracked by default, every click, mouse move is sent to a third party.<p>3) The GDPR opt out process fails every time.<p>Solid violations of GDPR, well done.
I'm a little jealous if I'm honest. I'm going to guess that the junior high I went to still doesn't have the resources for a club like this.
