That real, life-sized mech Korean company Hankook Mirae debuted recently isn't just for show. Its designer, Hollywood SFX veteran Vitaly Bulgarov, has posted a video on Facebook showing the robot taking its first steps. And, yes, it had a pilot on board. The 13-feet-tall, 1.3-ton machine was created to work in extreme conditions where humans cannot go unprotected. It won't be able to go on rescue missions anytime soon, though -- not without a power source that's portable enough.
