Handiii: A Sub 0, 3D Printed, Smart-Phone Connected Bionic Arm (VIDEO)


Exiii,*a Japanese prosthetics*company, has developed a smartphone-connected, EMG-controlled prosthetic arm called the handiii COYOTE. The device*was developed as a low cost, highly functional*myoelectric arm, but ended up as a pretty stunning piece of hardware which*can be manufactured for less than $300.

The handiii*was developed*with*three core design principles in mind:

• Outsource the sensor processing and control algorithms to a standard smartphone
• Reduce the number of motors needed to one per finger (rather than one per joint)
• Use 3D printing to reduce manufacturing costs, and enable easy repair and customization

The handiii transmits EMG sensor information from the arm to a smartphone using*a wireless communication*link embedded under the prosthesis. The smartphone algorithms interpret these signals to control the arm. Exiii are quick to point out that these algorithms are based on work by*Mr. **ritaka Kawashima of the National Rehabilitation Center for Persons with Disablities, and Mr. Masahiro Yoshikawa of Nara Institute of Science and Tech**logy in Japan, for their motorized prosthetic hand called the*Finch.

The handii allows the wearer to toggle through a range of programmable grips such as a pinch grip, five fingered grasps etc. via a small button on the elbow.*Though it has been k**cking around since late 2013 as a prototype device, the latest version of the arm has a much sleeker finish and wireless functionality. Exiii has enlisted two expert user evangelists to assist them with testing and developing the arm which needs to be custom-made to fit varying arm sizes.

Without a doubt the most striking aspect of this device is its low cost and beautiful design. It is **t surprising that the team have won a number of prestigious design awards for the*handiii*and envisage a wide range of customizable, 3D printable textured skins for their device in the future.
