What is robotic inspection in AGL?
A self-driving ground robot carries the sensors along the lights — scanning, tagging each result and reporting defects for an engineer to confirm.
Robotic inspection uses a self-driving ground robot, usually wheeled or tracked, to carry cameras, light sensors and positioning equipment along an approved route beside or over the lights. It scans each light, tags the result with its position and time, and reports possible defects.
It suits long, repeated passes and short closure windows, and the same route each run shows what has changed. But the robot only travels and scans: the aerodrome approves the route and air traffic control clears the work, an engineer confirms each finding and does the repair, and weather, surface and obstacles can limit it. It runs within the approved inspection programme, not in place of it.
- Plan. Approve the route and area, get clearance, and set the software boundary.
- Drive. The robot follows the lights, avoids obstacles and stops on a fault or alert.
- Scan. Camera and light sensor capture each light with its position and time.
- Return. The robot leaves the movement area and docks at its base.
- Report. Results upload and a defect list goes to an engineer to confirm.
- Repeat. The same route on the next run shows change and confirms repairs.
A self-driving machine carries the sensors along the route, so the same pass can be repeated with little manual effort.
The wider idea of instrument-based checks. A robot is one platform for it; fixed sensors and vehicle-mounted units are others.
Frequently Asked Questions
Q1What is robotic inspection in airfield ground lighting?
Inspection carried out by a robot that moves itself, usually a wheeled or tracked ground vehicle, along an approved route beside or over the lights. It carries cameras, light sensors and positioning equipment, and records what it finds against position and time.
Q2How is it different from automated inspection?
Automated inspection is about the checks: instruments and software that capture and compare results. Robotic inspection is about the platform: a machine that carries those instruments along the route on its own. A robot is one way to carry out automated inspection.
Q3What can an inspection robot check?
Whether lights are lit, how bright they appear compared with set limits, the condition of lenses and fixtures from images, and the position of each fixture. The checks depend on the sensors it carries, and some physical checks still need a person.
Q4Who controls where the robot goes?
The aerodrome. The route is approved in advance, access to the movement area follows the normal permits and air traffic control clearance, and the robot is supervised. A boundary set in software keeps it inside the approved area and it stops on a fault or obstacle.
Q5What are the limits of robotic inspection?
Heavy rain, standing water, snow or poor surfaces can stop a robot or spoil its readings. It must avoid aircraft, vehicles and obstacles, needs a clear access plan, and cannot repair anything. Its findings are confirmed by an engineer before action.
Q6Does a robot replace the required inspections?
Only if the aerodrome’s approved procedures and the regulator accept it. ICAO Annex 14 and national rules set what is inspected and how often, so a robot is used as part of that programme and does not replace it.

Recognising an AGL system visually is the first step. The next step is knowing how to design, install, test, commission and maintain them correctly.
