The Myoelectric Arm Project
A project at Vigyan Ashram, Pune aims to set up capabilities in India such that myoelectric hands in the price band of ₹10,000 to ₹30,000 are available for fitting to those in need. At a later stage the project would work with other institutions such that a few engineering colleges have centers for Prosthetics and Exoskeletons for further innovation. The world is in a ferment in these two areas. A lot of development is taking place with implications for public health and military and with many Indian scientists working abroad in these areas.
The innovation involved
- 3D printing with Acrylonitrile butadiene styrene (ABS) / Polylactic acid (PLA) and flexible filaments
- Myoelectric sensors
- Stepper motors, Servo motors and DC motors with continuously variable transmission (CVTs) to power the myoelectric arms
- Value Engineering to reduce the cost from ₹3,75,000 to ₹10,000 per item
