It's a bit late, but here's a film of my robot, Perfect Titan, at Stockholm Robot championship 2012, I'll do a proper write up about it later when I've finished my current build. It's powered by two FingerTech Gold Spark 63:1 motors with FingerTech Cobra wheels. They're a fantastic combo, my next build; Perfected Titan(since it's sort of like v2.0 of Perfect titan) will have the 50:1 Gold Spark motors and Cobra wheels. Crazy grip in those wheels. Here's a picture of Perfect Titan: The big blob in the front is a bunch of sinkers made for fishing I bought for cheap at Överskottsbolaget held together with shrink tube and tape.
