The root cause of the Sim-to-Real Gap lies in the imperfect approximation of the real physical world by simulation models, with sources including aerodynamic simplifications, distorted sensor noise models, unmodeled motor response delays, and visual domain differences.

UnverifiedSim-to-Real transfer refers to the phenomenon of significant performance degradation when a model trained in a simulation environment is deployed to real hardware, rooted in the reality gap.79% similarVerifiedThe key challenge of sim-to-real transfer lies in the reality gap—simulation environments cannot perfectly reproduce real-world details such as friction, flexible deformation, and sensor noise.77% similarVerifiedThe hard-to-bridge gap between the simulated world and the real world, known as the Reality Gap, stems from fine-grained discrepancies such as motor response delays, joint friction, sensor noise, and ground material differences77% similarUnverifiedThe Sim-to-Real Gap refers to policies trained in simulation failing due to factors such as real-world sensor noise and actuator latency; domain randomization is a common method for narrowing this gap.76% similarUnverifiedCommon sources of the Sim-to-Real gap include dynamics modeling errors, sensor distortion, actuator non-idealities, and contact and collision modeling.75% similar
