Incheon International Airport on Oct. 14 became the world's first airport to use indoor self-driving vehicles and cart robots that carry passenger luggage.
The airport said the gizmos are intended to aid the mobility of special needs users and boost noncontact services.
The self-driving vehicles are undergoing trial operations, with two installed at the departure and arrival gate of Terminal 1 and the departure gate of Terminal 2 to assist users with special needs such as the disabled, senior citizens or pregnant women.
Two of the airport's six self-driving cart robots are installed at both terminals and the duty-free shopping section. They tag along with a passenger while transporting his or her luggage and guide him or her at the destination.
Those with special needs get priority in the use of these devices, but regular passengers can also use them as long as no inconvenience is caused to others.
The airport said it hopes the adoption of the two devices will boost user convenience and bolster the airport's reputation as a smart airport.
