Electromyography (EMG) data controller

This project is currently in development and it's meant to process EMG muscle data using machine learning algorithm to generate control commands.

This is a student project, it's goint to have a basic machine learning algorithm to control a Arduino-Uno based robotic hand or any other device or it could be used as a controller. Arduino send voltage from non-invasive on-skin electrodes (EMG). Repository contains arduino source code for passing raw EMG data to computer and python3 code for analyzing and sending control signals.

What's done:

• Arduino code that sends voltage data
• Python module emg_api.py that provides API to connect, synchronise and read data in real-time from Arduino
• Server on Flask emg_server.py for real-time reading, processing and analyzing data from Arduino and sending processed data (e.g. Fourie transform) it to localhost:5000/emg/{channel} in json format. For now it's processing this data:
  • Fourie transform for frequency spectre analysis
  • Standart deviation calculation that will be used for ML as input
  • Just a raw voltage data
• Live web dashboard emg_web_dashboard.py made with Dash by Plotly that reads data from server and visualize it
• Vue.js web dashboard prototype (made just for fun to see what possibilities are available)

What's going to be done:

• Implementation of TensorFlow for analyzing hand gestures
• Build web virtual hand to be controlled by EMG
• Redesign server side to get rid of http data sending to front-end
