Getting tired of your puny human arm? Now you can replace it with a new arm that is probably nowhere near as good but is much more robot-y. The Edge robotic arm kit from ThinkGeek does require about two hours worth of snap-together assembly, but once you’ve got it put together, you’ll have a robot grabber arm with five motors, five degrees of freedom, and a wired control panel with five controls on it. It rotates and bends all kinds of ways, can reach out 13 inches and up 15 inches, lifts up to 100 grams, and comes with an LED to illuminate what you’re trying to pick up. It’s only $50 at ThinkGeek.com
