Physics and Dynamics Engines
The core of any simulation is its ability to mimic real-world physics. Accurate collision detection, gravity, friction, and inertia are essential. High-end tools like NVIDIA Isaac Sim leverage GPU-accelerated physics to ensure that robot movements behave realistically under load, which is critical for complex tasks like bin picking or heavy-payload material handling.
CAD Import and Compatibility
To be effective, simulation software must support standard CAD file formats (such as STEP, IGES, or SolidWorks files). This allows users to import their specific factory floor layouts and proprietary end-of-arm tooling. Seamless integration prevents the need to rebuild mechanical components from scratch within the simulation software.
Vendor-Specific Libraries
Many industrial robot manufacturers provide proprietary simulation software that includes digital twins of their own hardware. For example, FANUC ROBOGUIDE, ABB RobotStudio, KUKA.Sim, and Siemens Process Simulate include libraries that allow users to program in the robot’s native language. These ensure that the virtual code is 1:1 compatible with the code running on the physical controller.
Connectivity and Data Exchange
Modern simulation platforms must communicate with other systems. Look for support for OPC UA, ROS (Robot Operating System), and PLC (Programmable Logic Controller) emulation. This connectivity is vital for testing how a robot will interact with surrounding sensors, conveyors, and human-machine interfaces.
