That'd be awesome.
I had a thought. I'm going to be teaching my daughter and a couple of her friends Arduino programming using Pololu Zumo robots over the break. While I was contemplating logistics, I thought about having a pair of robots here (we are all using identical robots), which I would flash with the competitor's code before each match. No reason we couldn't do something like that and have a zoom call or some kind of streaming to broadcast the competition. Line following, sumo, or whatever else.
Hope you're all doing well and staying healthy.
