The star of such clips as Wii murder robot and Robotic Arm Ride 2: The Brain Smearer is up for sale on eBay. For a Buy it Now price of $24,969, you too can strap yourself to the arm and smash your head into the concrete like a too-ripe melon.
Of course, the seller recommends you NOT using this as a ride-robot, but be honest. Why else would you want a used FANUC S420iW Industrial Robot that was once used in a Nissan Motor plant? To build your own Altima?
