"How does it drive?!?!" Team 857's bot

[Adam Krajewski]

We've got a second video uploaded showing how we load balls into the bot. Also, thanks to Xobes, the webpage is Netscape compatible (At least on Linux). Mary reformatted the first video so it's a reasonable size (8MB), too.

As for the controls, we kicked around many ideas. We wanted a controller that would allow the driver to use the entire range of motion the drivetrain is capable of. The original Killough specs calls for rotation sensors to determine the velocity of each wheel. We found a way around it. We did not use the gyro; we found no need for it. The control system we eventually stumbled upon on doesn't require feedback control, is incredibly simple, and is our little secret for the time being.
