Typical difficulties of sim-to-real transfer include the difficulty of simulation environments in fully reproducing real-world contact mechanics, friction, sensor noise and lighting changes, which causes policies trained in simulation to degrade in performance when transferred to real machines (reality gap).

UnverifiedThe idea of sim-to-real transfer is to train robot policies in a virtual environment and then deploy the model onto real hardware; its advantages are low cost and massively parallel generation of training data, but the physical differences between simulation and reality lead to a "reality gap."80% similarVerified增强学习领域用'sim-to-real gap'描述在模拟环境训练的机器人策略因现实物理差异而在真实世界失效的现象78% similarVerifiedThe sim-to-real gap refers to the phenomenon where policies trained in simulation often suffer significant performance degradation when transferred to the real world, and domain randomization and system identification are commonly used mitigation techniques.76% similarVerifiedSim2real (simulation to reality) refers to training a robot's locomotion policy in a physical simulation environment and then transferring it to real hardware, with the core challenge being the gap between the simulated world and the real world (Reality Gap).76% similarUnverifiedThe training and validation of physical AI relies heavily on the Sim-to-Real Transfer closed loop.74% similar
