Naw, that one doesn't move...but plenty of people are building mechs that you can actually ride in:
"Building an 18-foot tall robot (or “mecha”) in the backyard of his home in Anchorage, Alaska. The anime-inspired behemoth is actually a giant exoskeleton that you jump into and ride, letting you take eight-foot strides or, presumably, fight invading aliens. He hopes to have it finished by next summer and will demonstrate it by demolishing a few cars at the local racetrack."
