Narita's security robot patrol is an early deployed example
SECOM's cocobo robot is documented as patrolling Narita in 2022. The record supports a physical security application, but does not establish the current extent or operating benefit.

The operating setting
Airport patrols involve repetitive observation across public spaces. A mobile robot can collect and process information along a route, but useful alerts must still reach a person with responsibility to act.
Narita's cocobo story predates the current wave of generative-AI assistants. This is a security-device application with different validation requirements.

01 / Deployed
Narita's security robot patrol is an early deployed example
The operational problem
Security staff need to identify incidents without relying solely on a robot's interpretation of what it sees.
What the sources report
Industry and supplier accounts in June 2022 describe SECOM's AI-labelled cocobo robot patrolling Narita.
Why it matters
The defined operating setting makes questions about patrol coverage, intervention and false alerts practical rather than theoretical.
What remains unproven
No recent source verifies continued service, autonomous coverage or independent security performance.
Evidence supports a reported claim; it does not automatically establish a measured operating benefit.
The wider register
What else is happening at Tokyo Narita?
The wider register below keeps any other recorded technology separate from this selected operational story. Its source and status should be assessed independently.
No additional publicly listed deployment records.
Aerostack assessment
An updated account from Narita or its security operator would determine whether this remains a live operating example.
The published sources remain available alongside the underlying implementation record; claimed results should retain their original attribution.
