If you’ve ever wanted to build your own Darth Vader Robotic Arm, now you can. It’s made from 45 snap together parts that come together to build a working robotic arm. The arm is able to grip and manipulate lightweight objects. No batteries are required, the robotic arm is hand powered (yes that last phrase sounds really weird- a hand powered arm?). Learn about basic robotics and construction. Just don’t get too close when it’s complete or someone might try out the death grip on you.Price $39.99 from ThinkGeek.
