Edge Robotic Arm Kit
Ever wish you had an extra hand? Now you can build your own spare appendage in about two hours with this Edge Robotic Arm Kit ($50). Once assembled, the wired remote controls 5 axes of robotic movement that give the arm an impressive range of motion. The gripper sports an LED light to help out with precision movements as you maneuver your new arm to perform various tasks. There’s plenty to be learned about gears and motors while you assemble the arm, making this kit a great introduction to the workings of robotics.
