these things seem to be getting better at moving and at doing tasks faster than moore's law ,i was rather impressed with last years version of robomule and the scuttly deer shaped things but these are almost looking practical.
as they seem to have solved the "dalek problem" in terms of them being able to cope on a variety of surfaces,with stairs etc i expect they will be found in the wild quite soon.
i recon studying the terminator movies for hints might be a good idea if they get ai as well as practical skills .
the weaponised ones are already quite fierce but these ones seem quite charming.
