I saw Buddy'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?

    $\begingroup$ long story short Yes. Actually, you can build SLAM with only one sensor. More sensors more accuracy. $\endgroup$

I did casually search for something like this a year or two ago. "Sparse sensing" or "sensing limited" were the sort of phrases that cropped up.

Kris Beevers has some interesting publications in this sort of area, such as SLAM With Sparse Sensing. His general approach was to maintain previous sensor readings while changing the direction of the robot, to build up a "scan" comprising several sets of readings. This approach might be sensitive to encoder errors or any other movement inaccuracies during the scan, but still worth investigating.

SLAM can be done Using many different way, in this case, Yes Buddy can map around him using its sensors : RGB camera, IR sensor, Ultra sound Sensor, Encoder. The result depend of the algorithme you are using.

We are also working on a 3D camera to allow buddy to have a better input of the world.
