Stelarc's Walking Head Robot. Sitting atop six piston-powered legs, an LCD screen displays a creepy animated face to lull you into submission once the robot sees you with its ultrasound sensors. It then makes faces as if to trick you into believing it's really not here to destroy you and yours like some monster from The Thing. It would be one thing if the Walking Head Robot was small, but its 4-meter footprint (13-foot) is big enough to make even the largest of men turn white. To be fair, however, this robot looks to be well-constructed out of aluminum, stainless steel, acrylic, and pneumatic actuators because, after all, it's here to kill us (oops). We're begging for some video of this thing in action, so stay tuned.
