Domain Randomization for Robust Robot Learning
Domain Randomization for Robust Robot Learning Domain randomization is the idea that, instead of trying to perfectly match simulation to reality, you randomize simulation parameters widely enough that reality just looks like "one more variation" the policy has already seen. It's one of the highest-leverage techniques in sim-to-real robot learning, and it's straightforward to bolt onto an existing…
Domain randomization is a technique used to enhance the robustness of robot learning in simulation, which can then be transferred to real-world applications. The core principle behind domain randomization is to train a policy on a wide distribution of simulated scenarios, including variations in lighting conditions, object colors and textures, camera positions and lens distortions, friction, mass, damping values, and sensor noise levels.
By doing so, the policy learns to handle a diverse range of real-world scenarios, rather than being caught off guard by unexpected challenges. This approach is considered a high-leverage technique in sim-to-real robot learning and can be easily integrated into an existing MuJoCo or other simulator pipeline.
