I don't think anyone (on Wikipedia) cares about which robot is best at what and such, and keeping those up to date would be a pain anyway, last update was claimed to be in 2009. So I think the RR@H champions should be removed.
The influencial robots section needs to be adjusted some. For example to me Phoenix's entry reads like an advertisement, and is YersiniaPestis' passing Shadow for a bit really worth mentioning? Plus a few are missing like Raiko/RaikoMX (First Open Source Surfer), Chalk (Open Source kNN), BulletCatcher (Bullet Shielding), MoxieBot? (Bullet Shadows? Was it the first?).
But I wouldn't mind seeing a list of past competitions on there, might give the game more clout.
