I've resurrected the project site as part of Mohawksoft.org (http://linuxpcrobot.mohawksoft.org). A few cool things came out of it. I'm told some of the motor control stuff got used in the player project and the "yield" paradigm I wrote about in 2012 is now part of the Arduino main-line. (Whether it was because of this site or independent development coming up with the same solution would be an interesting study.)

I still have the chassis and may do something with it at some point, it was fun, but it is now hopelessly obsolete. I've let the domain go.

So long, and thanks for all the fish.
