Hmmm, I just watched a video with that in, ok looks impressive. However there were no kids playing with it at all, a couple of shots with some adults tentatively touching it briefly. Actually let [say three] kids loose on it and within 10 mins you'd have a pile of bent pistons. I find it curious as to how this actually seeks people out, it seemed to be moving on a predefined course.
Robots seldom fare well in the real world as HitchBot discovered recently.
Does not appear to be tracking/interacting with humans so there's a gap between what it does and what the creator would like it to do, so are safe for the moment.
