The robot is armed with air quality detectors that the airport team says help monitor the terminal for pollutants. This robot, along with two others, constitutes a fledgling automated fleet that’s been rolled out by ABM, a maintenance and facilities company operating at LaGuardia and dozens of other airports and facilities. At the link in bio, read more about how the strange-looking robots are keeping the terminal clean. #fastcompany #laguardiaairport #robot
