Nbot: Exploded Views




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 slashdotted several times. We have a paper describing the network traffic statistics and data on how our little webserver responded to and survived the onslaught. Here's a whole website about my robots in some 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 Inertial Measurement Sensor and Odometry. 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.
