A robot simulator for the upcoming FIRST Robotics Competition season, since we won't be able to meet in person at the school! This is last year's actual robot code, running in FIRST's official hardware simulator, piping data over websockets to Godot, where we're using the simulator's output to drive a physics simulation.
It's maybe not the most "handmade" thing I've ever done, but I think it's a good reminder of what is possible when all the parts of your system are well-designed and easy to use!
