Inspiration
Imagine 300 people controlling a drone, what could go wrong?
What it does
The users control the drone from a website, while we stream the drone FPV on the big screen
How I built it
Using open source stuff like Docker containers, Python, Flask, OpenCV... The Tello SDK allow us to control the drone, while the Flask frontend provides the UI. We got the domain locodrone.online, which redirects to the Ngrok tunnel that points to our localhost where the webpage is served.
Challenges I ran into
- Connecting to the drone and to the internet at the same time. Since we need to use the laptop's wifi (for the drone)+Ethernet (to publish the web) we created a Ethernet bridge from one laptop to another.
- Streaming the video, the Tello SDK documentation is pretty short so we checked the low level source code to understand how to use it.
- Connecting multiple clients to Flask in a reliable way
Accomplishments that I'm proud of
Make the pipeline work. It is actually very complex
What I learned
Tello SDK, Docker and Flask
What's next for Loco Drone!
Fly on a big room controlled by 300 people!
