Instruction:

1. Follow the instruction in the sb_web_app folder to start a HTTP and ROS server within your ROS setup for survivor buddy. Turn on the Camera.
2. Run 'python3 sb_project.py'.

Description: The file sb_project.py has the implementation of 5 Behaviors - Attention, Mirroring Face, Youtube Interaction, Dance & Sleep.

Observer pattern has been used to implement this. Its brief working is explained below:

1. In this a subject like Camera Perception will notify its observers when it gets a new image.
2. The notification from the subject updates the values at the observers like Face Cartographer to process the image for face recognition.
