Check this out everything from Tour Guide Robots to Fire Fighting Robots:
IEEE Robotics and Automation Society has a nice list of robot companies and research labs at: IEEE Robotics and Automation Resources (http://www.service-robots.org/IEEE-start.php)
When SNORRT gets done we will put our tour guide robot there too. (Don't know what SNORRT means? Ask Ryan :-) )
AAAI also has a great robot resource page at:
AAAI AI Topics on Robots (http://www.aaai.org/AITopics/html/robots.html)
