Simulation physics gaps teach robots tricks that fail in the real world
binarybits · x · 2026-09-04
Citing Kai's new piece on robot data, the author explains a key reason training robot manipulation in simulation doesn't transfer well: because simulation can't perfectly model real physics, models learn exploits that work only in the simulated environment and fail in the real world — a vivid illustration of the sim2real gap.
