T-Rx pictures and capabilities
 

All team members agree: T-Rx 2002 is the best robot that we've built yet - at least in doing what we designed it to do. Like Joe J. said - whether or not we designed it to do the right thing is another question.

In case anyone puts together a robot database, here's some info to start it off. First, links to some key pictures in the gallery:

Hope you find it useful :) See you in Philly, New Haven, and hopefully EPCOT!
