Found this 'neato' (wait for it) little project on diydrones.com. The project details the workings and implementation of a hacked LIDAR device from a Neato XV-11 vacuum cleaner robot—for the purpose of reusing it in your own personal robotic projects. Makes for some interesting reading. Check it out some time....

Saw these LIDARs scavenged
Saw these LIDARs scavenged from NEATOs and sold on E-Bay for about $100. I exchanged emails with the seller once. The draw backs for me was the size (~5"x~6"), weight (can’t remember) and power requirements (300 mA). That aside, the device is pretty cool. I saw a video of it in use with the data displayed radar-like. The guy making the video walked across the room and you could see his two legs move on the display as he walked. Pretty cool.
