In this project, we will explore the integration of sensors and controls to enhance the functionality of a prosthetic hand. Specifically, we will learn how to use a button, rotary encoder, and an ultrasonic distance sensor to automatically program the NeuroMaker Hand to grasp objects when detected within a certain range.
The rotary encoder will adjust the distance threshold at which the hand reacts to an object, allowing for customizable sensitivity. Additionally, a button will help to release the object from the hand’s grasp, providing manual control over the prosthetic’s operations. By the end of this project, we will have a deeper understanding of how sensors and actuators can work together in robotics to mimic human movements and responses.
This project combines practical skills in electronics and programming with theoretical knowledge in biomechanics and robotics. It's an excellent way to see how real-world problems can be solved through STEM disciplines, specifically in the area of assistive technologies.
