 3D Printed Animatronic Hand
3D Printed Animatronic Hand
Hairygael has put together an amazing project. He 3D printed an entire robot hand and forearm and used hobby servo motors and an 
Arduino board to drive it. As you can see in the picture above, the hand looks amazing and if you watch the video below, you will see it moves very smoothly and it is actually quite strong.

If you have the 3D printing skills and a 3D printer you could build your own robot hands (

right) thanks to the design files posted on Thingiverse.
