Isaac Sim and ROS 2: define what crosses the simulation boundary
By NOVEMIQ · Engineering explainer
A simulation integration needs a deliberate boundary: which commands enter the simulator, which observations leave it, and which clock the software uses. The ROS 2 bridge connects these worlds; it does not establish physical validity.

Understand the boundary
NVIDIA’s reference architecture describes ROS 2 communication with Isaac Sim through its bridge. Use that connection to exercise application behavior while retaining a clear record of the simulated robot, environment, and configuration.
What to review
Before comparing runs, document the software versions, simulation time configuration, sensor settings, and initial conditions. Otherwise a behavior change may reflect a different setup rather than a better algorithm.
Put it into practice
Label every exported image as simulation. Keep a separate hardware validation plan for properties the model may omit, including friction, compliance, communication delays, and sensor imperfections. A visually convincing scene is not deployment evidence.
