What It Is
ArduPilot is the world's most widely deployed open-source autopilot system. It supports an extraordinary range of vehicles: multicopters (ArduCopter), fixed-wing aircraft (ArduPlane), ground rovers (ArduRover), boats (ArduBoat), and even submarines (ArduSub). It is completely free, open source (GPLv3 license), and community-driven — maintained by a global team of volunteer developers and supported by the ArduPilot Foundation.
ArduPilot runs on Pixhawk-family flight controllers (the same hardware as PX4), as well as Linux-based boards like the CubePilot, Emlid Edge, and BeagleBone Blue. The ground station software — Mission Planner (Windows) and QGroundControl (cross-platform) — provides mission planning, real-time telemetry, parameter tuning, and log analysis.
What makes ArduPilot the go-to choice for students and hobbyists is its documentation and community. The ArduPilot wiki is the most comprehensive open-source autopilot reference available. The discussion forums have thousands of active users answering questions daily. From a first-time quadcopter build to a custom VTOL research platform, ArduPilot has a guide, a forum thread, and a parameter for it. More student drone projects worldwide run on ArduPilot than any other autopilot system.
Aerospace Applications
Student Competition Platforms
ArduPilot is the dominant autopilot for student drone competitions, AUVSI SUAS (Student Unmanned Aerial Systems), and university capstone projects. Its extensive documentation, large user community, and hardware flexibility make it the lowest-risk choice for teams building custom aircraft on tight timelines and budgets.
Commercial Agricultural Drones
Many commercial agricultural drone platforms run ArduPilot or ArduPilot-derived firmware for crop spraying, mapping, and monitoring. Companies in this space build on ArduPilot because the license (GPLv3) allows modification, and the autopilot's terrain-following, spray-control, and autonomous mission capabilities are mature and field-proven.
Search and Rescue
ArduPilot-equipped drones are used by search and rescue teams and humanitarian organizations worldwide. The autopilot's grid-pattern survey mode, automatic camera trigger, and long-range telemetry make it suitable for systematic area searches. Organizations like WeRobotics and OpenDroneMap communities use ArduPilot platforms for disaster response mapping.
Underwater Exploration (ArduSub)
Blue Robotics builds its BlueROV2 — the most popular low-cost underwater ROV — on ArduSub, a variant of ArduPilot. ArduSub provides depth hold, heading hold, and autonomous navigation for underwater vehicles. This extends ArduPilot's reach into oceanographic research, pipeline inspection, and marine biology — domains with clear parallels to space exploration.
Multi-Vehicle Coordination
ArduPilot supports multi-vehicle operations where a single ground station controls multiple drones simultaneously. Research groups use this for swarm experiments, coordinated search patterns, and distributed sensing. The MAVLink protocol enables heterogeneous fleets — copters and planes operating together on a shared mission.
Getting Started
High School
Build and fly your first autonomous drone. ArduPilot has the best documentation for beginners.
- Start with the ArduPilot wiki "First Time Setup" guide — it walks through every step
- Build a quadcopter with a Pixhawk flight controller (~$200–400 total for a basic build)
- Download Mission Planner (Windows) or QGroundControl (Mac/Linux/Windows)
- Configure, calibrate, and fly in Stabilize mode first, then Loiter, then Auto (waypoint missions)
- Use the ArduPilot SITL simulator if you want to practice before flying real hardware
Undergraduate
Move beyond flying to understanding and modifying the system.
- Learn to read and analyze flight logs using Mission Planner's log review tools
- Tune PID controllers for custom airframes — understanding how each gain affects flight behavior
- Build a fixed-wing aircraft (ArduPlane) or a rover (ArduRover) — different vehicle types teach different concepts
- Write Lua scripts for custom mission logic (ArduPilot supports onboard Lua scripting)
- Integrate companion computers (Raspberry Pi, NVIDIA Jetson) for computer vision and autonomy
- Enter the AUVSI SUAS competition or build a capstone project around ArduPilot
Advanced / Graduate
Research-level: modify the autopilot internals, build novel vehicle configurations, contribute to the project.
- Study the ArduPilot codebase (C++) — the EKF, attitude controller, position controller, and navigator
- Implement custom flight modes or control algorithms for research
- Build a VTOL (vertical takeoff and landing) aircraft — ArduPilot's QuadPlane mode supports dozens of VTOL configurations
- Develop ROS/ROS 2 integration for advanced perception and planning
- Contribute code to the ArduPilot GitHub repository — the project actively mentors new contributors
- Participate in Google Summer of Code through ArduPilot (they are a regular GSoC organization)
