Goals

Enhancing Accessibility to Advanced Prosthetics

The primary goal of the PrecisionMOTION project was to construct a functioning prosthetic hand capable of accurately mimicking user inputs. Leveraging SOLIDWORKS and 3D printing technology, a model of the prosthetic hand was fabricated and assembled to replicate human-like dexterity. This project aimed to create a reliable and precise system that could improve accessibility to advanced prosthetics.

Another critical objective was to ensure the prosthetic design remained cost-effective without sacrificing quality or functionality. By using readily available materials and components, the project targeted a production cost that was up to 50% lower than similar commercially available device. This balance aimed to make advanced prosthetics accessible to a wider range of users, particularly those in underserved communities.

Programming

Optimized Control Through Advanced Sensors

To achieve high precision, a control program was developed using C++ on an Arduino platform. The system utilized flex sensors to capture user input and servo motors to reproduce fine motor movements. With optimized code and real-time data processing, the prosthetic achieved a reaction time of less than 200 milliseconds between input and movement execution.

Results

Accurate and Affordable Prosthetic Solutions

The prosthetic hand successfully recreated user movements with an accuracy of over 90% in real-time tests. Adjustments to the flex sensors and servo motor calibration enhanced movement fidelity, ensuring smooth operation. The project demonstrated the potential of affordable, custom-built prosthetics to provide a functional and user-friendly alternative to commercial solutions.
