If you have 2 NXTs lying around and you are moderately interested in testing some potentially interesting new NBC and NXC API macros then I would definitely be interested in hearing from you via email.

The second set of arms on Mike's robot gives it better mobility. They make its overall tread length much longer, so it can treat stairs like a ramp instead of, well, stairs, and that makes it faster at climbing them. The arms also let it raise the (...)
