Here's another two-person build. This time the second person was Joe Jackson. I didn't run out of LEGOs this time though. We dissected a remote control car and attached (mostly taped) the parts to a LEGO chassis. It runs well and looks... blocky. Anyway, here's a picture.
It is front-wheel drive and as you may have guessed, the wheels with lots of tape around them are the drive wheels. The wheels operate independently to steer because we couldn't find any servos.
