I went to watch a 'Roaming Robots' (
www.roamingrobots.co.uk) at Fenton Manor Sports centre just over a month ago, which was awesome (and odd because I heard about it the next day after randomly remembering Robot Wars and thinking damn that show was cool).
So much so that myself and a few mates are hoping to have a go at building our own combat robot this summer, starting when A-Levels are over (less than a week now for me!). If we do get started on it, and people are interested, I could make a thread on these forums and do a project log type thing.
