The best I saw was one that completes docking in 16 seconds: https://www.youtube.com/watch?v=WwWccjAD2i8 https://www.youtube.com/watch?v=WwWccjAD2i8 Given that this simulator supposedly maps closely to the actual interface on the spacecraft, it's funny to imagine SpaceX hooking it up to the real thing and seeing how it fares. Succeed or fail, it would be a pretty wild ride.

  If you've ever watched the movie Armageddon, you'll know this is par for the course.

  Not too dissimilar to what they're doing at Tesla with the self-driving beta, really.

  Fuel economy would be awful, though. Dragster style.

This sim was released for the first human mission Demo-2. Back then I also created an autopilot, written in Go and running in the browser via WebAssembly: https://github.com/mbertschler/dragon-iss-docking-autopilot https://github.com/mbertschler/dragon-iss-docking-autopilot This autopilot doesn't use the rotation and translation rates as input, just the momentary values. It also uses the same control function for all axes. Video: https://youtu.be/jLTr6UwuSd4 https://youtu.be/jLTr6UwuSd4

Impressive, along with your Github page. Great work!

Is it basically a PID controller?

  the code is in the youtube video description [1]; definitely not PID control [1] https://gist.github.com/ggerganov/092b86a59fa34926998953701ae22ca1 https://gist.github.com/ggerganov/092b86a59fa34926998953701a...

    It's AI! :P I saw at least two autopilots that used PID control in a couple of different ways. They all needed tuning though because any moderate control input would send them spiraling off into the void.
