- Supports aircraft, rovers, boats and submarines
- Enormous hardware compatibility
- Two decades of field testing
Isaac Lab
Isaac Lab runs thousands of simulated robots in parallel on a single GPU, cutting reinforcement-learning training from days to minutes.
- Thousands of parallel environments on one GPU
- Photorealistic sensors for perception training
- Direct path from simulation to real hardware
Key differences
ArduPilot is autopilot firmware, while Isaac Lab is gPU simulation framework. Their licenses differ (GPL-3.0 vs BSD-3-Clause), which matters if you ship a commercial product. In short, ArduPilot fits anything autonomous that moves — in the air, on the ground or on water, and Isaac Lab fits teams with NVIDIA GPUs training locomotion or manipulation at scale.
Which should you choose?
Choose ArduPilot for anything autonomous that moves — in the air, on the ground or on water. Choose Isaac Lab for teams with NVIDIA GPUs training locomotion or manipulation at scale.
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 Isaac Lab easier to use?
