How did They Make That Huge Comic-Con Robot?

Last month we posted a cool video of a huge cosplay robot that features a human inside a gigantic costume of what might well be a RoboCop robot villain. Tested, Jamie Hyneman and Adam Savage’s website, explains how the robot was built: it has a person inside, with the robot’s giant arms mirroring the motions of the operator’s real arms, which are obviously the lower set. It’s cool!
