Residual Error Tracking Between Real Robot Telemetry and Shadow Physics Models

Comparing expected physics model outputs against actual robot sensor readings to identify mechanical faults and external sabotage.

Residual Error Signal Generation

The shadow twin executes the identical commanded trajectory as the physical robot. Divergence between simulated wheel torque and physical motor current reveals mechanical binding, bearing spalling, or payload shifting.

Early-Stage Bearing Fault Identification

Fast Fourier Transform (FFT) analysis of torque residuals identifies bearing race defects weeks before audible acoustic noise or physical breakdown manifests.
