Summary

Dynamics-completed demonstrations cut quadruped velocity-tracking error 63.1% on a Cartesian command grid.

Animal demonstrations usually show only a few directions. OmniMimic combines time reversal, constrained dynamics completion and sagittal reflection to create robot-specific supervision beyond those motions, then widens commands toward target velocity ranges. A shared policy uses gait-specialized residual experts for corrections. Across four simulated gaits, it reduced foot-position error 12.9% at forward and backward reference speeds and velocity-tracking error 63.1% on a uniform command grid versus the matched baseline.
