You could probably buy 10 cheap webcams and put them all around the robot and get some vision algorithms to turn them into 3D scenes, which are avoided/mapped? This seems like a pretty well understood and constrained problem.
It also sounds like a lot of robot perception work on object permanence, which from what I understand is getting a noisy perceptual input to conform to a unique symbolic representation of the object (e.g. this is the same T-shaped-part-of-the-hallway that I was at 5 minutes ago.) They mention the SLAM algorithm as being similar, and it doesn't seem to have any much greater abilities to accomplish goals for example. It basically sounds like a better inference algorithm.
