Build Your Own 3D Printed Robotic Hand in Less Than an Hour

The company Open Bioncs has developed a new robotic hand that can be built in less than an hour. Most of the parts can be self-printed.

Tutorials, instructions and a bill of materials can be found on Instructables, Thingiverese, YouMagine or on the company’s website. Even the STL files needed are available for free download. The project has been named “Ada Hand” by Open Bionics. The prosthesis is controlled by a custom PCB designed around an ATMEGA2560 microcontroller. All parts are placed inside the hand and the micro controller can be programmed using a USB-connection and the Arduino programming language. As a consequence it is easy to experiment with the hand.

There are 4 3D-printed parts: 3 made of PLA or ABS plastic and one part made of Ninjaflex. If you want, you can buy different parts or even all parts on the company’s website. A kit with all parts (mechanic, electronic and 3D-printed parts) costs 500 pound. When needed, parts can be adjusted to fit your own needs because all components are open source. To drive the development forward, Open Bionics has created a forum where interested people and developer can discuss new technologies and possibilities. Open Bionics aims to create an affordable alternative to conventional prosthesis.
