Simulating a 2D quadcopter from scratch

daww: Author here.I've spent the last six months replicating the paper "Champion-level drone racing using deep reinforcement learning" and now I'm writing down the blog posts I wish I had along the way.Any feedback is welcome, especially as I'm a bit unsure if I struck the right balance between being concise and not requiring too many prerequisites.Also if you're working on RL and robotics (especially aerial), let's connect!

dvh: Isn't it just bi-copter?

kabir_daki: Physics simulations from scratch are great learning projects. Did you implement your own PID controller for stabilization? That's usually where things get interesting — tuning the gains without it oscillating to death.

andai: Your voice betrays you, Claude!

palata: No, it's a quadcopter setup, but simulated in a 2D world (I guess for simplicity). A bi-copter would require tiltrotors, which is different.
