FUURAA thesis
Robot precision has value only through a defined process characteristic and accepted product result.
Engineering map
Turn the title into engineering objects that can be observed, measured and reviewed.
Each layer states the boundary to establish and the evidence needed for the next decision.
Variation
Separate part, fixture, tool, robot, sensor, process, environment, operator and measurement contributions.
Control and trace
Connect calibration, recipe, tool state, lot, alarm, intervention and disposition to each quality record.
Verification questions
Write the questions first, then decide whether a demo, test, pilot or operating record can answer them.
Each question needs an object, conditions, denominator, threshold and accountable decision owner.
- 01
Which accepted characteristic does the robot metric support?
- 02
Is the measurement system capable relative to the tolerance?
- 03
How are drift and special causes detected and contained?
- 04
Are rework and escaped defects included in the result?
Evidence to preserve
Enable the next reader to reconstruct conditions, results, failures and the decision.
A conclusion alone loses reviewability; raw records, configuration and exclusions matter too.

Requirement and measurement-system definition
- 02
Evidence package 2
Condition-stratified quality and process-capability results
- 03
Evidence package 3
Trace from result to configuration, lot and disposition
Scope boundary
State what this evidence still cannot be generalised to.
- 01
Repeatability, path accuracy or a gauge reading alone does not establish process capability or customer acceptance.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
