FUURAA thesis
Entering a narrow space is not the same as completing an inspection mission.
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.
Inspect
Measure sensor view, resolution, localisation and defect detectability.
Retrieve
Test reversal, extraction, module separation and blocked-path procedures.
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 real geometry and contamination were tested?
- 02
Can findings be located for repair?
- 03
How does the robot return after power or actuator loss?
- 04
What infrastructure must be isolated before entry?
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.

Evidence package 1
Geometry and environmental-envelope map
- 02
Evidence package 2
Defect-detection and localisation results
- 03
Evidence package 3
Blocked, damaged and lost-power retrieval trials
Scope boundary
State what this evidence still cannot be generalised to.
- 01
Prototype traversal metrics are configuration-specific and do not establish arbitrary-pipe, hazardous-area or live-infrastructure readiness.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
