There is a nice mention of nBot and my other robots in an article by Erik Hellweg for the
February 2005 issue of
PC World Magazine.
Here is what

similar article from Yugoslavia,
This webpage and nBot have also had the honor of being

foreign tongue (Hungarian?).
Most of these robots have been built in my home machine shop.
I've written some e-mail in response to questions about the robot concerning
things that I haven't fully documented. These include a PID
speed controller, shaft-encoder Odometry
and Dead-Reckoning, stereo Sonar and how an

Subsumption programming for the SR04 and jBot Robots. The
DPRG has a new contest to encourage the development of autonomous off-road robots, and I've written a set of email postings as introductory tutorials for solving the
DPRG OutDoor Robot Challenge.
