High School Digital Electronics: Final Project, 2016
The Inspiration
The Inspiration
My junior year of high school, I was in a Digital Electronics class and were tasked to make a final project involving either a Raspberry Pi or Arduino. This project was the first time I was exposed to these types of micro-controllers and was very exciting for me to do.
I had seen a YouTube video about a student, about my age at the time, who make a neuro-controlled prosthetic arm in his bedroom and then made a TED talk about it. With only a semester to make my own, this is the project I developed.
The Idea
The Idea
The servos were connected by string to the fingers, then with control from sliders on a Raspberry Pi screen, the servos would turn and clench the fingers. The bigger application was designed to make the same movements, but instead of with sliders on a touchscreen, it would be with vision sensing with hardware such as a Leap Motion.
Hardware
Hardware
- Raspberry Pi
- The Pi controlled all aspects of this design. It was attached to the back of the touchscreen, ran the touchscreen sliders using a library called Kivy, and rotated the correct servos for the finger that was to be controlled
- Servos
- 5 different servos to control the 5 different fingers
Software
Software
- Python - Kivy
- Kivy is a Python library that allowed the sliders to be on a touchscreen instead of just controlled with a mouse
Other Materials
Other Materials
- Robotic hand toy
- String
- VEX metal part
