Sawyer should not need any introduction. It is a state-of-the-art robot with a 7DOF arm that can maneuver in tight spaces and automate various manufacturing tasks. As it turns out, it also makes a good Darth Vader. To celebrate May the 4th, Rethink Robotics turned one of their robots into Darth Sawyer.
The robot can pick up and wield a lightsaber. The above video shows it in action.
