HAZOP (Hazard and Operability Study) methodology
Deviation: barrel not gripped
Possible causes: attach failed
Consequences: an item left unattanded
Mitigating actions: tried grabbing again
real world deployment will require obstacle avoidance especially with humans around
hardware stop/override
multiple sensors to detect humans
SIL2/SIL3 safety integrity levels
a robot operating in a haazrdous environment can spread contamination or make it more unsafe
stopping and human oversight
can displace human workers
need to retrain them
transparency and explainability
should not overtrust system
