Hengbot Sirius robot dog looked up at me, and I reflexively petted its face, stroking down between the eyes as an on-screen menu appeared. This, in a nutshell, is Hengbot Sirius's problem: it's a robot AI dog that has consumer aspirations but is really almost entirely built for nerds and geeks.
Looking more like an X-ray of a dog than a real hound, Sirius can walk, bark, growl, dance, stand on its head, and fall over quite a bit like someone poured a bit of brandy into its water bowl.
