Martian Tripod Prototype

It's a little small and doesn't have a mounting point for a heat ray, yet.

Apparently, robot designers are worried that they're not creating automatons that are creepy enough, because a team of engineers at Virgina Tech have put something together that will give even the toughest of men chills. The robot in question is the three-legged STriDER (Self-excited Tripedal Dynamic Experimental Robot, not to be confused with CMU's Strider) which balances itself on two legs and then flips its body 180-degrees, bringing its third leg forward with the motion. According to project leader Dennis Hong, "STriDER's gait is closer to that of a human walking than most bipedal humanoid robots you see today," adding, "This is how we humans walk, we do not actively control our knees, we just let them swing."
