The XRB3 is only the beginning of a much more powerful map-making robot. It looks like they are off to a good start. Check out the link for more pictures and videos of the XRB3.
XRB3 is powered by an AVR ATMEGA324P micro controller on a custom board that I made. Although he is fully autonomous, he is using an XBEE module to communicate with my PC for debugging (and eventually with other robots). Onboard sensory includes: 3 Sharp IR sensors (for wall following and obstacle detection), an SRF-05 sonar sensor and AVRcam.
