[Easton] was looking to enter his local science fair and needed a project that would wow the judges. After considering it for a bit, he decided that an animatronic hand would be a sure winner. Many animatronic projects we have seen are connected to a computer for control purposes, but his is a bit different.
[Easton] wanted to be able to control the hand in real time with his own movements, so he sewed some flex sensors onto a glove and wired them up to a custom Arduino shield he built. The Arduino is also connected to an XBee radio, allowing it to interface with his animatronic hand wirelessly.
He built the hand after studying anatomical drawings to better understand where finger joints were located and how they moved. He cut up pieces of flexible wire tubing to build the fingers, reinforcing them with Lego bricks. He ran fishing wire from the finger tips to five independent servos to provide the hand’s motion. Another Arduino with an XBee shield was used to control the hand and receive wireless signals from the glove.
