Simulation
Virtual environments used to train, test, and evaluate embodied agents before real-world deployment.
Direct answer
What is Simulation?
Virtual environments used to train, test, and evaluate embodied agents before real-world deployment.
Definition and scope
Virtual environments used to train, test, and evaluate embodied agents before real-world deployment.
Physics engines model bodies, contacts, sensors, and environments; domain randomization helps transfer policies to reality.
Why it matters
Simulation lowers cost and risk while enabling repeatable experiments and large-scale data generation.
How it works
Physics engines model bodies, contacts, sensors, and environments; domain randomization helps transfer policies to reality.
Beginner learning path
Build a simple environment, define observations and actions, and compare simulated behavior with real constraints.
