Has in practice this ever happened in the UK champs.

"In the UK featherweight championship, you get 1 point just for entering the arena in the group stages. That 1 point can be the difference between making it straight through and having to compete in a play-off . This is especially helpful if you take an absolute battering in a fight and have limited repair time, and it’s beneficial to all competitors, not just those with a particular design/weapon type."

Has anyone with a one wheeled robot made it through to the main competition.

If I do make it to the FW UK champs, and am confronted with a one wheeled machine, I think I might spend three amusing minutes watching it try to get across the arena whilst my machine dose figure of eights just to comply with the rule you do agree with.

I think we can agree to disagree on the points you raised. I am just about to stick the wheels on the lunch box, Pictures to follow.
