Features

ProtoTwin is the first and only browser-based industrial simulation platform. You can view, modify and collaborate on projects from anywhere in the world. There is nothing to install and updates are entirely automatic.

Core Framework Features

Effortlessly build powerful and reliable models with real-time physics. ProtoTwin was designed to be intuitive and simple to use. making it possible to quickly iterate on your designs and test new ideas.

Deterministic Models
Run your model many times with the same initial conditions and the result will be identical. Your simulations are deterministic by default, even across reset events, different web browsers and operating systems.
Simplified Scripting
The integrated scripting environment supports code auto-completion and IntelliSense. Type and syntax errors are detected. Built-in types, functions and properties are intuitive and fully documented.
Zero Compile Time
The engine includes a TypeScript API, eliminating the need for slow script compilation, allowing you to iterate and test models rapidly. The inspector refreshes automatically to reflect any changes.
Configurable Timestep
Create powerful and precise models by configuring the frequency of the physics simulation. ProtoTwin simulations run at 100Hz by default, but it is possible to run models at frequencies beyond 10kHz!

Physically Based Rendering

Our bespoke rendering engine simulates real-world light dynamics and material interactions, generating exceptional visualizations that capture subtle details in your scenes. Rendering quality is configurable, allowing you to favor performance when running on hardware with limited capabilities.

Incredible Performance

Performance is uncompromised. Our simulation engine uses a purpose-built data-oriented architecture, allowing you to simulate dynamic digital twins and factories with thousands of industrial robots and machines in real-time.

Custom Physics Colliders

ProtoTwin Simulate can handle complex mechanisms where you need to model precise collisions between parts. Our purpose-built custom collider tool can generate high-fidelity colliders for CAD meshes with complex topology. You can customize settings to balance fidelity with runtime performance. Import the colliders into ProtoTwin Simulate at the click of a button.

Simulate in Virtual Reality

Enter the simulation! Connect your VR headset and launch ProtoTwin VR at the click of a button. Observe and interact with your models in real-time inside virtual reality. No separate viewer application is required.

Python API Connection

Use our Python API for deep reinforcement learning and AI robotics research. Programmatically load models, step the simulation, read signals and write signals. Create Gymnasium RL environments. Generate high-quality synthetic data using our physics simulation engine. Train machine learning models to control industrial and humanoid robots with dynamic motors.

Virtual Commissioning

Connect to physical PLCs for controls testing and virtual commissioning. Prove your CAD and test your control logic in the digital twin before you commit to building the real machine. ProtoTwin can connect to a wide range of PLCs through many supported protocols, including Siemens S7, Allen-Bradley Ethernet/IP, TwinCAT ADS, Omron FINS, Modbus TCP, Mitsubishi MELSEC and OPC UA.
