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
MuJoCo
MuJoCo simulates contact-rich dynamics fast and accurately. DeepMind open-sourced it, and it is now the default for reinforcement learning on robots.
- Accurate contact dynamics at very high speed
- Free since DeepMind released it
- The de-facto standard in RL papers
Key differences
ArduPilot is autopilot firmware, while MuJoCo is physics simulator. Their licenses differ (GPL-3.0 vs Apache-2.0), which matters if you ship a commercial product. ArduPilot leans more advanced-friendly, whereas MuJoCo is more suited to intermediate users. In short, ArduPilot fits anything autonomous that moves — in the air, on the ground or on water, and MuJoCo fits training control policies before touching real hardware.
Which should you choose?
Choose ArduPilot for anything autonomous that moves — in the air, on the ground or on water. Choose MuJoCo for training control policies before touching real hardware.
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
