If you have access to a 3D printer there's a whole new world of fun and devices you can create, and one example of this has been demonstrated by staff from Instructables with their robotic arm. Using four servos and controlled by an Arduino with a customised control panel, the arm can rotate, lift up and down along with a claw.
It's a lot of fun, and the individual pieces are designed so the arm could snap together once they have been printed. The motion is quite fluid and opens up possibilties of experimenting with artificial intelligence and robot control. A quick demonstration of the process is shown in the following video:
