When I saw this, my first thought was that it could only happen in Japan. My second thought (yeah, I'm a nerd) was that it's not really a robot, since it doesn't appear to be even semi-autonomous. When you watch the video, the guy flips a switch to get it to feed him a tomato. It's no more a robot than my toaster or ice machine, though it is
an entertaining waste of time.
Now, when it responds to a vocal 'Tomatan, feed me a tomato!' and rotates the tomato after each bite to expose unbitten surface, then I'll be impressed.
