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
appears to be a
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

are integrated on the jBot robot. I also have a new article that covers
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.
Here is a link to the current attempt at a live video feed.
