Have you ever had the urge to stick a fork in the outlet, but concluded that it wasn't worth the risk? Well, we have the answer: let a robot do it for you! This 3D-printable extension replaces the gripper on this OWI robot and features a revolute joint, a prismatic joint, a plug head that houses copper wire prongs for reliable contact, and a camera mount to let the robot find the socket!

The two servos are MG90Ss, and the webcam is a $20 model made by Logitech. The screw sizing may be modified carefully in Blender, but there are holes for eight 2.5mm O.D. MG90S kit screws and one larger 3.3 mm O.D. screw. Remember to remove the metal bricks from the webcam base to make it lighter.
