- Optimized Performance: Efficient handling of model conversions to boost computation speed.
- Smooth Integration: Seamless connection between physics simulations and modern AI autonomy stacks.
- Robust Data Consistency: Reliable propagation of external model updates within simulations.
In short, OpenPLX empowers teams with a flexible, open-source machine modeling format that supports live synchronization, promotes reusability, and enables seamless cross-domain integration.
What are the key features of OpenPLX?
Key features include:
- Modular and Extensible Models: Reusable constraints and hierarchical inheritance for flexible system design.
- Seamless AI and Simulation Integration: Direct external model referencing and signal-based communication support real-time, physics-driven AI interactions.
- Live Synchronization: External models (e.g., URDF, CAD) update dynamically within the simulation, reducing manual conversions.
- Broad Industry Applications: Proven performance in robotics, industrial automation, and digital twin simulations.
How does OpenPLX work?
OpenPLX uses a declarative syntax that simplifies complex machine modeling. For example:
is defines objects:
CraneComponent is MechanicalSystem
BoomModel is CraneComponent
StickModel is CraneComponent
trait defines reusable properties:
trait ExcavatorComponents:
boom is CraneComponent
stick is CraneComponent
becomes applies traits to modify objects:
Crane is MechanicalSystem:
with ExcavatorComponents
boom becomes BoomModel
stick becomes StickModel
This approach allows engineers to add realistic physical behaviors to models without managing low-level physics details.

How Does OpenPLX Work in Simulation?
It’s important to note that OpenPLX is a definition format—it specifies how your simulation models are structured and interact. However, to run a simulation, you’ll need to integrate OpenPLX with an external physics engine or simulation environment. These engines interpret the definitions provided by OpenPLX and bring them to life by handling the complex computations required for realistic physics, dynamics, and interactions.
Who is behind OpenPLX?
OpenPLX is created by Algoryx and has been developed partially through research projects funded by Vinnova and the European Commission Horizon 2020 project.
