Thanks for the pictures! That looks pretty sweet. What's the black wire tied on the bot? A tether? Weird color for a tether...
When we were strapped for cash last year, our '09 bot was stripped of all electronics. We've restored everything on the robot to original working condition, sans pesky bumpers that just take up space.
Tank drive and a four button lift/dump mechanism makes it really easy for anyone to drive, and it just functions with such majesty. Probably should swap out the regolith wheels for some standard wheels soon.
Our '11 robot was tons of fun to demo at our Rising Freshmen Night because it's almost as simple: tank drive, five-button grabber and joystick lift, with two button minibot deployment.
'10 was a glorified pizza box on mecanum wheels, and therefore, hard to show off.
