UnverifiedThe 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 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.77% similarVerifiedThe key challenge of Sim-to-Real is the Reality Gap, which typically requires domain randomization to enhance the robustness of policies.69% similarUnverifiedThe modality gap phenomenon was systematically analyzed in the 2022 research paper "Mind the Gap".63% similarUnverifiedSim-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.62% similar
