What each one is
Genesis
Genesis combines a very fast physics engine with generative scene creation — you describe an environment in words and it builds a simulable world.
- Extremely fast simulation, even on CPU
- Scenes generated from natural language
- Unified engine for rigid bodies, fluids and soft matter
Nav2
Nav2 handles mapping, localisation, path planning and obstacle avoidance for wheeled and legged robots on ROS 2.
- Complete navigation stack, not just a planner
- Used in commercial deployments
- Behaviour trees make the logic auditable
Key differences
Genesis is generative physics engine, while Nav2 is autonomous navigation. Their licenses differ (Apache-2.0 vs NOASSERTION), which matters if you ship a commercial product. Genesis leans more intermediate-friendly, whereas Nav2 is more suited to advanced users. In short, Genesis fits researchers who need varied training scenes without modelling each one, and Nav2 fits ground robots that need to get from A to B without human input.
Which should you choose?
Choose Genesis for researchers who need varied training scenes without modelling each one. Choose Nav2 for ground robots that need to get from A to B without human input.
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 Genesis or Nav2 easier to use?
Genesis is generally the easier of the two to get started with, while Nav2 rewards more setup with more control.
Are Genesis and Nav2 free?
Genesis is free and open source (Apache-2.0), and Nav2 is free and open source (NOASSERTION). Neither charges for the core software.
Can I run Genesis and Nav2 locally?
Genesis: yes · Nav2: yes. Both can be used without sending your data to a third-party cloud where their setup allows.
