FUURAA thesis
Obstacle detection becomes a safety function only inside a complete risk-controlled operating system.
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.
Protect
Measure sensing coverage, response, stopping and residual implement hazard.
Govern
Control access, communication, restart authority and incident learning.
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 encounter classes were physically tested?
- 02
Does the implement reach a safe state too?
- 03
How are authorised people distinguished from intrusions?
- 04
Who confirms the area before restart?
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.
- 01
Evidence package 1
Encounter and occlusion hazard analysis
- 02
Evidence package 2
Detection-to-stop validation with final implement
- 03
Evidence package 3
Access, restart and incident records
Scope boundary
State what this evidence still cannot be generalised to.
- 01
Passing an obstacle-detection test does not prove safety for every human or animal encounter, implement or environmental condition.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
