About the project

A myoelectric control system is one in which the operation of the output apparatus is controlled by the electric potentials which accompany the contraction of one or more muscles. A myoelectric prosthesis is connected to the residual limb via a custom fabricated socket. As a part of a course project, I chose to make a prototype of a myoelectric prosthetic arm. The aim is to make the entire arm such that it can be 3D printed and work on the principle of artificial tendons. We plan on designing the entire arm such that it can at least do some basic stuff like pinching, holding a pen and grabbing a mouse/ glass of water.

Why this design?

After doing a literature review, I found the design which uses artificial tendons. So with the given time constraint, I thought this would be a perfect design and using some MG995 Servo motors will help me move my fingers. The design is such that it has sufficient space to accommodate all the servo motors along with the electronics. This design also ensures that the tendons don't intertwine. And most important it can achieve 7 degrees of Freedom (DOF).
