About this 3D model

Hello! My name is Palii Alexandru, im studying mechanical engineering in Romania, and this is my work from past 2 years. In this contest i will present the Version 2 2019 of the myoelectric prosthetic hand device, but i want to show some of my past work on my first myoelectric hand device. Myoelectric prosthetic hand device-V1 2018 (8 months of work)https://www.youtube.com/watch?v=KpdVQwZl6Kkhttps://www.youtube.com/watch?v=hBKG3AHqRQMhttps://www.youtube.com/watch?v=KpXcD_BGUTU Myoelectric prosthetic hand device-V2 2019 (6 months of work)https://www.youtube.com/watch?v=DheOzkUhBH4&t=153s 3D Printed-Tested Working mechanism demonstration of Version 2. https://youtu.be/IK6NzF8wwkQ The price for the electronics, torsion springs, shaft, potentiometer, arduino, is around 80$ + myoelectric sensor 40-50$ In the video you will see that the finger is a bit slow, but this is not a problem, because i can change it to a faster motor, that can increase the speed by 3.5 times. Achievements to the project: Creating a liniar actuator with a screw motor that provide a great force that can hold 7kg with no problem. Using a H-bridge microcip(potentiometer-picture) that i took from a sg90 servo, and conecting it with a liniar potentiometer to work like a position sensor. All the mechanism is inside of the palm. Human size prosthetic hand. Creating of a torsion spring mechanism for the fingers for a smooth and precise movement Amp consumtion: aprox. 1.2 Amps on full load. Easy to understand and build Cheap to make it All components can be easy to found on internet All the work for this project is made by me alone, from mechanical solution to design, electronics and C++ programing. I do not own a 3d printer, the investment that i did is around 700$, most of the money was spend on 3d printing parts to test the thickness of some components and improving them. Answers for the Judging Criteria: Impact: This project can be a alternative option for people in need. The cost of a prosthetic hand can go from 10.000$ to 120.000$, and from my reaserch, none of them can recreate a realistic human movement. Feasibility: The project can be achieved because all the mechanical and electrical components can be buy at a very low cost. Research: This project was made by reasearching high cost Prosthetic devices. The biggest improvement in this project is the liniar actuator that i create, an actuator with a great precision of movement a good torque, a mechanism that can hold a good weight.
