I'm a HUGE fan of Battlebots & Robot Wars. After seeing some homemade RW vids made by Lastdaydawning, ALJ123456, Gump747, etc., I made my tournament: Robot Arena 2.
I built my own robots as well. They are:
Wheely Whacko, Wedg-E, & 360-Arc Pounder. here's how they're doing so far:
Wheely Whacko (retired): 4-8
Wedg-E: 22-26
360-Arc Pounder (retired): 0-6
More about them coming soon...
