John, If you are interested in doing some LIDAR stuff you might check out the XV-11 projects that were going on a while back. The Neato XV-11 robot vacuum has one of the lowest cost LIDAR devices around and a lot of people have been hacking them. Here are a few threads you might find interesting: http://www.hizook.com/blog/2009/12/20/ultra-low-cost-laser-rangefinders-actualized-neato-robotics http://diydrones.com/profiles/blogs/the-open-lidar-project-hack http://diydrones.com/profiles/blogs/30-laser-rangefinder We've had a Neato XV-11 for a few years and it is a really cool robot vacuum cleaner. As far as I know the first and only robot vacuum cleaner with LIDAR. The iRobot Roomba that everyone knows is just a toy compared to the XV-11.
