Virtual models can ignore friction, motor response delay, center-of-gravity offset, and structural deformation, but real machines cannot ignore these factors, so the same animation that is smooth on the virtual side may exhibit jitter, position deviation, or even motion failure on the physical side.

UnverifiedThe sim-to-real gap is a classic challenge in robot control, because physics simulators typically model contact friction, joint clearance, structural flexibility and actuator dynamics in a simplified way.65% similarUnverifiedHigh-dynamic movements such as the long jump are particularly sensitive to the gap between simulation and reality, being affected by variations in friction, motor response delays, and material deformation.65% similarUnverifiedEarly generative video models are prone to problems such as anatomical errors, limb interpenetration, and incoherent motion trajectories when handling two semantically unrelated elements (such as a bird and a bicycle) and actions requiring physical plausibility (such as riding).63% similarUnverifiedSimulators cannot fully capture all physical details of the real world; for example, contact mechanics, friction coefficients, material deformation, sensor noise, and actuator delays are often simplified or ignored in simulation.63% similar
