FUURAA thesis
Useful legged mobility includes knowing when not to move and how to contain a loss of balance.
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.
Fall consequence
Map swept volume, impact, payload and nearby people.
Recovery
Define self-righting, isolation, retrieval and restart.
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
How are falls defined and counted?
- 02
What stops motion before instability grows?
- 03
Can a payload change balance limits?
- 04
Who authorises restart after a fall?
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.

Scope boundary
State what this evidence still cannot be generalised to.
- 01
ISO 18646-5 measures locomotion performance; it explicitly is not a safety-validation standard.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
