Archive for the ‘3D-Printed Prosthetic Hand’ Category

To help a patient in his country with a congenital limb deficiency, Buzi Nguyen has designed a 3D-printed transhumeral—above the elbow—prosthesis prototype. The device features 10 degrees of freedom, including independent control of four fingers and a thumb, along with movement capabilities for the wrist and forearm.

The prosthesis is powered by a number of Arduino boards and a Raspberry Pi, and equipped with computer vision to track and choose grip patterns for object handling. It can also potentially be operated via brain-computer interface and electromyography.

A demonstrate of all the currently supported features can be seen in the video below.

3D-printed appendages are, as one might suspect, generally meant for those that are missing a limb. Moreover, there are many other people that might retain partial functionality of a hand, but could still use assistance.

Youbionic’s beautifully 3D-printed, myoelectric prosthesis is envisioned for either application, capable of being controlled by muscle contraction as if it were a real body part.

As seen in the video below, the Youbionic hand can manipulate many different items, including a small box, a water bottle, and a set of keys. Functionality aside, the movement is extremely fluid and the smooth black finish really makes it look great.

The device is currently equipped with an Arduino Micro, servos, various sensors, a battery pack, and a few switches. Even the breadboard appears to be very neat, though one would suspect the final version will use some sort of PCB.

You can learn more and order yours on Youbionic’s website.
