Rolling with the Roller Walker

The name may sound like something you'd use to help infants get around, but the Tokyo Institute of Technology's Roller Walker is a distinctly kiddy-unfriendly metallic hunk of speedskating meanness. It doesn't look much in the photo and we suspect it'll be fairly clunky when walking, but it redeems itself when it's slinking around in high-speed mode with the wheels on its feet flipped out (watch
video). We're not sure what speed it maxes out at, but it does look like they're reining it in to avoid taking out bystanders. Anyway, bottom line is we want to see a bigger, meatier version of this chasing Will Smith around if they ever make I,
Robot II.
