+Avatar - BCI Application with NAO Robot Control
+Author: Youssef Elkhouly
+Date: October 2025
+
+Description:
+    This module implements the backend for the Avatar BCI application, which integrates
+    brainwave reading, drone control, and NAO robot control. The application uses PySide6
+    for the GUI framework and connects to various hardware controllers.
+
+Key Features:
+    - Brainwave data acquisition and processing
+    - Drone control via Tello SDK
+    - NAO robot connection and control with configurable IP/Port
+    - Machine learning predictions (Random Forest and Deep Learning)
+    - File shuffling and data transfer utilities
