What each one is
ArduPilot
ArduPilot is the autopilot firmware flying a large share of the world's open drones, plus ground rovers, boats and submarines.
- Supports aircraft, rovers, boats and submarines
- Enormous hardware compatibility
- Two decades of field testing
Gymnasium
Gymnasium is the maintained successor to OpenAI Gym: one API that every RL algorithm and environment speaks.
- The interface the whole RL ecosystem implements
- Dozens of environments included
- Actively maintained, unlike the original Gym
Key differences
ArduPilot is autopilot firmware, while Gymnasium is rL environment API. Their licenses differ (GPL-3.0 vs MIT), which matters if you ship a commercial product. ArduPilot leans more advanced-friendly, whereas Gymnasium is more suited to beginner users. In short, ArduPilot fits anything autonomous that moves — in the air, on the ground or on water, and Gymnasium fits learning RL, or benchmarking an algorithm against a known baseline.
Which should you choose?
Choose ArduPilot for anything autonomous that moves — in the air, on the ground or on water. Choose Gymnasium for learning RL, or benchmarking an algorithm against a known baseline.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
Frequently asked questions
Is ArduPilot or Gymnasium easier to use?
Gymnasium is generally the easier of the two to get started with, while ArduPilot rewards more setup with more control.
