PX4 autopilot

Probabilistic roadmaps, PRM, are efficient in high-dimensional configuration spaces.

Flight control integration, the navigation brain talks to a real autopilot, PX4 and ArduPilot are the two mature open frameworks with broad hardware support, and MavLink is the protocol that carries commands and telemetry between your navigation code and the flight controller.

If you want to see how deep this integration goes on cheap hardware, that's the whole subject of my RC Drone Reverse Engineering series.

What, AI agent, actually means in 2025? Here's where I want to sharpen the original framing, because, AI agent for navigation, meant something vague a couple of years ago and means something specific now.

The, um, Well, that's, that's actually been an exciting part now too, because we, you know, we started with, we started with group one drones, like your hobbyist quadcopter.

The first drone we ever had was a, um, a PX4 mod drone that's been used for basically like fifth grade STEM education.

Like that's what it's for.

It's just a hobbyist drone, right? But on the early bootstrap kind of days, these, you could buy on a, you know, shoestring budget, you can buy these things.
