Accuracy Budget — Robot-Carried Inspection Sensor
RSS error-stack for robot-carried inspection sensor: four dominant terms vs the process requirement.
Measurement cells expose the dirty secret: robots repeat ~10× better than they position absolutely. Calibrated absolute accuracy (the 150 µm term) decides whether robot-carried scanning can certify a dimension or merely flag outliers for the CMM.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Accuracy Budget — Robot-Carried Inspection Sensor
Accuracy Budget — Robot-Carried Inspection Sensor computes the governing relationship e_RSS = √(e₁² + e₂² + e₃² + e₄²) — independent error sources live as you type. Measurement cells expose the dirty secret: robots repeat ~10× better than they position absolutely. Calibrated absolute accuracy (the 150 µm term) decides whether robot-carried scanning can certify a dimension or merely flag outliers for the CMM. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Accuracy Budget — Robot-Carried Inspection Sensor
- 1Enter your values — Repeatability, Absolute accuracy residual, Sensor noise, Temperature drift and more (sensible defaults are pre-filled).
- 2Read the live results: RSS total (±), Worst-case sum (±), Margin vs requirement.
- 3Check the "with your numbers" line to see e_RSS = √(e₁² + e₂² + e₃² + e₄²) — independent error sources substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Accuracy Budget — Robot-Carried Inspection Sensor?
