Watch as poor Asimo takes a spill during a presentation in Japan. The operating team doesn't skip a beat, quickly pulling out a screen to give Asimo some privacy.

Poor little guy. His voice just keeps on talking while he's all piled up on the floor.

I saw Asimo at the University of Minnesota a couple years ago. While the robot's ability to balance and maneuver stairs is interesting, I was a little bummed to see that everything was orchestrated from behind the curtains, Wizard of Oz style. It didn't appear that Asimo was equipped with any autonomous behavior. So really-and feel free to disagree-I think falling down a flight of stairs is probably the most human thing he's done to date.
