In this project, a AIY Vision kit is mounted on top of a Pan Tilt Hat, and a Raspberry Pi detects and follow faces. This repo contains the python script controller.
- Mount the vision kit on the Pan Tilt Hat as shown in the picture.
- Connect respectively the Yaw and Pitch servomotors to the PIN A and B of the Vision kit card.
- Connect the ground and 5V of the servmotors to the card.
- The Raspberry Pi, the vision kit and the two servomotors are together consuming more than the 500mA of a regular USB port. In my case, I had to use my 2A Samsung phone charger.
- Switch on the Raspberry Pi.
- When the Raspberry Pi is running, disable the startup demo with
sudo systemctl stop joy_detection_demo. - Start the script with
python3 follower_main.
The pan-tilt-hat keeps the camera facing any detected face. The color of led button varies from red to green depending on the smile of the face.
