🤖 Gesture Control Publisher for TurtleBot (MediaPipe + ROS 2 + Gazebo)

This project allows you to control a TurtleBot in Gazebo using hand gestures, captured via your webcam and interpreted using MediaPipe in a Jupyter Notebook. This repository is only responsible for detecting gestures and publishing direction commands, which are then received by a ROS 2 node that moves the TurtleBot accordingly.

🪄 How It Works

1. MediaPipe is used to detect and classify hand gestures in real-time using your webcam.
2. Based on specific hand gestures (like open palm, fist, etc.), the notebook publishes direction commands like:
   • forward
   • backward
   • left
   • right
   • stop
3. These commands are published to a ROS 2 topic (e.g., /gesture_direction).
4. A separate ROS 2 Python script subscribes to that topic and moves the TurtleBot in Gazebo accordingly.
