Thanks! How heavy is a standard nonadrive? Five motors, 9 wheels, and four pneumatic cylinders, that must add up...

On a sheet-metal chassis, which can be lighter than a more standard box-tubing chassis.

For further questions on the Nonadrive, you might want to take a look at the following two threads (and yes, there are two, one for each team that used it): 217 and 148--and definitely watch the videos that open the threads. (Warning: watching said videos may cause a sore jaw, due to said jaw hitting computer, desk, or floor.) Unfortunately, I can't seem to find tech specs...

But I do know where CAD files can be found!

To echo what Chris said, you need to know what you're doing to try a nanodrive. They'd have had a hanger on their robots in competition if they hadn't decided to reinforce their drive and make other improvements--and that's another scary part, they improved it from the videos.
