...that's the point. Some people have strong emotional reaction when they see this robot being kicked even though this is clearly, obviously, a robot. They haven't, as far as I know, built in any emotional engagement stuff. They could easily build in a few movements - robot pauses, cranes head towards human companion, makes noise, robot continues - which would freak a few people out.

It's a pretty remarkable robot.

yes, and hopefully, 10 years down the line it is not merged with an ai which can take a dim view of it's predecessors being kicked around on some carbon based life form's whims and fancies (after watching it's genesis)

ANNs have feelings as well ;)
