Area of Science:

Robotics
Biomedical Engineering
Machine Learning

Background:

Controlling highly dexterous prosthetic hands remains a significant challenge.
Current mechatronic prostheses offer multiple degrees of freedom but lack natural control over finger position and force.

Purpose of the Study:

To develop an advanced control system for dexterous robotic hands using surface electromyography (sEMG).
To enable intuitive, real-time control of finger position and force for prosthetic hand users.

Main Methods:

Utilized machine learning algorithms combined with a downsampling technique.
Applied sEMG signals to predict grasp intentions and required force levels.

Main Results:

Achieved accurate on-line, real-time control of finger position and force for a dexterous robotic hand.
Demonstrated high accuracy in determining user's intended grasp type and force magnitude.

Conclusions:

The developed system significantly improves upon the state-of-the-art in feed-forward control of mechanical hands.
Opens new possibilities for amputees to achieve finer and more natural control over their prosthetic hands.
