OpenHand 3d printable open source robotic hand is a strong and flexible gripper for you robot

3d printed robots are not toys anymore and very serious open source projects are emerging like strong DIY 3d printable robotic arm or small DIY robotic production cell.

We could see very soon home based robotic mini factories where robots, cnc machines, pick-and-place machines and 3d printers make anything you can imagine.

If you want to develop your own project you can use this robotic hand developed at Yale.

It comes in several configurations with different number of fingers. Finger grippers are made from different combinations of flexible and hard materials moved by fiber tendons. The resulting movements show that it can manipulate many different types of objects.
OpenHand is an open source projects so all the files are available publicly even including a code to modify the design.

Here are some videos of different OpenHand versions manipulating objects:

In this video they show Hybrid Deposition Manufacturing (HDM) production process of OpenHand components where different materials are used to create object with functional properties. The process is easily replicated at home workshop:
