Re: hurdler or herder?
I think herding will prove to be more of a hassle than its worth. All but the best herders will likely spend more time trying to herd and control a ball than to just run around the track a second...

Re: Team 2214 Robot
Looks like a really nice robot, even more so for a rookie. Looks like it should be a very valuable addition to any team.

Re: Drive Systems... ...The FIRST Arms Race?

Re: How do you cheesehole?
Yup put a 2" hole saw in the drill press, apply a lot of cutting fluid or grease and just starting chopping. It will probably make a sound like somebody is dying but you've just gotta go with it.
