The robopocalypse may be coming sooner than we thought. This year, robotic engineers from around the world are showcasing their creations at 2010 Expo in Shanghai, China. So far, the most terrifying submissions include a giant robot baby and these guys: human-like robots that can climb walls.
Decked out in futuristic silver suits, the droids climb 50-foot walls by hooking their "feet" onto each rung. Luckily for us humans, it takes them about 20 minutes to reach the top.
