Existing Websocket Architecture Design

Socket connections

• Django webserver is served at port 8000

Inside scripts/ directory:

• manager.py creates websocket server at port 8765

The remaining files are all inside the static/exercises/ directory of the respective exercise:

• launcher.js connects to websocket at port 8765
• exercise.py creates websocket server at port 1905
• ws_code.js connects to websocket at port 1905
• gui.py creates websocket server at port 2303
• ws_gui.js connects to websocket at port 2303

Components

For each exercise there are two sides: the python part and the html part. They are connected in runtime through websockets (code_ws and gui_ws). For instance, in the Control Position drone exercise:

• the html part is here: https://github.com/JdeRobot/RoboticsAcademy/tree/master/exercises/templates/exercises/position_control
• the python part is here: https://github.com/JdeRobot/RoboticsAcademy/tree/master/exercises/static/exercises/position_control/web-template

The exercise.html and exercise.py (in the above locations) are connected at runtime through websockets.
