The idea of creating a myoelectric prosthesis of the hand appeared during the study of "Computer Aided Design systems", where, using research-based teaching methods, we decided to make the learning process more cognitive and create a computer model of the prosthesis of our desired design.
At the first stage of the research, we studied the electromechanical properties of human limbs, muscle innervation, signal transmission and blood supply.
At the next stage of research, we have already started prototyping the human limb
Prosthesis using computer design systems. Prosthesis construction
We decided to have a tendon-controlled system.
This prosthesis is as similar as possible to a real human hand in its function.
Flexibility and appearance, it can move the wrist 90° in both directions and
The fingers can move so that the prosthesis can grasp objects.
As for the technical means used for modeling, we used quite powerful and multifunctional program Fusion 360. To print the model, 3D interior of amateur level, material PLA. We used Cura software to process the drawings, a 3D printer, and servo motors to drive the moving parts.
