Griffin is working hard to put together a programmable prosthetic finger. His Q.E.D. is to eventually create an entire programmable arm, including a hand and five fingers. Griffin’s question is, “Can I create a fully functional robotic arm?” In order to create the whole arm, he is starting small with just one finger. He has printed the various parts of the finger on the 3D printer. He has an Arduino Uno which he will use to program the finger, a servo connected to the various joints for its dexterity, and various 3D printed pieces to complete the finger.
