A Practical Robot Calibration Checklist
Four situations
| Case | When |
|---|---|
| Tool frame | After every tooling change |
| Workpiece or user frame | When the fixture or part changes |
| Relative calibration | Between cooperating robots |
| Hand-eye | For vision-guided applications |
Verify afterwards
Check against a known point or master part, confirm deviation is inside tolerance, and record the date and result.
Common mistakes
Too few calibration points, no record, and forgetting to recalibrate after fixture changes.
