Myoelectric prosthetic hand device

Hello! My name is Palii Alexandru, I'm studying mechanical engineering in Romania, and this is my work from the past two years. In this contest, I will present the Version 2 2019 of my myoelectric prosthetic hand device, but I want to show some of my past work on my first myoelectric hand device. My Myoelectric Prosthetic Hand Device - V1 2018 (Eight Months of Work) https://www.youtube.com/watch?v=KpdVQwZl6Kk https://www.youtube.com/watch?v=hBKG3AHqRQM https://www.youtube.com/watch?v=KpXcD_BGUTU My Myoelectric Prosthetic Hand Device - V2 2019 (Six 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 cost 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, which can increase the speed by 3.5 times. Achievements of the Project: * Creating a Linear Actuator with a Screw Motor that Provides a Great Force and Can Hold 7kg Without Problem. * Using an H-Bridge Microchip (Potentiometer-Picture) That I Took from a SG90 Servo, and Connecting it With a Linear 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 Smooth and Precise Movement. * Amp Consumption: Approximately 1.2 Amps on Full Load. * Easy to Understand and Build. * Cheap to Make It. * All Components Can be Easily Found on the Internet. All the Work for This Project Was Made by Me Alone, From Mechanical Solution to Design, Electronics, and C++ Programming. I Do Not Own a 3D Printer; the Investment That I Did Is Around $700. Most of the Money Was Spent on 3D Printing Parts to Test the Thickness of Some Components and Improving Them. Answers for the Judging Criteria: * Impact: This Project Can Be an Alternative Option for People in Need. The Cost of a Prosthetic Hand Can Go from $10,000 to $120,000, and From My Research, None of Them Can Recreate a Realistic Human Movement. * Feasibility: The Project Can be Achieved Because All the Mechanical and Electrical Components Can Be Bought at a Very Low Cost. * Research: This Project Was Made by Researching High-Cost Prosthetic Devices. The Biggest Improvement in This Project is the Linear Actuator That I Created, an Actuator with a Great Precision of Movement, Good Torque, and a Mechanism That Can Hold a Good Weight.
