Sim-to-real is a key challenge in robot learning: simulators cannot perfectly reproduce real-world physical details (such as friction, sensor noise, and motor latency), causing performance degradation when policies are transferred.

VerifiedSim-to-Real transfer (the reality gap problem) is a fundamental long-standing challenge in robotics, and no universal solution currently exists.79% similarUnverifiedSim2real (simulation to reality) is one of the most central and challenging problems in the field of robot learning, with the core challenge being the Reality Gap between the simulated world and the real world.77% similarUnverifiedThe core challenge faced by reinforcement learning in robotics is extremely low sample efficiency—having a real robot perform millions of trial-and-error attempts is time-consuming and risks hardware wear—which has driven sim-to-real transfer and offline reinforcement learning to become research hotspots.73% similarUnverifiedA Reality Gap exists between manually constructed simulators and the real world, causing policy performance to degrade in reality71% similarUnverifiedIf a model can learn directly from a single real-world demonstration, it largely bypasses the sim-to-real gap problem.68% similar
