I saw [Buddy](https://www.indiegogo.com/projects/buddy-your-family-s-companion-robot/x/11637197#/story)'s page and want to purchase for my SLAM research. However, I wonder is it possible to program Buddy for SLAM? 

According to Buddy's spec, they're only few IR's, sonars and a camera. As I know, most SLAM algorithms are implemented with powerful sensors such as RGBD/stereo camera, or even laser range finder.

Are there any pepers mention about IR-based SLAM?
