INCHEON, South Korea - Robots will start roaming the country's largest airport this summer, helping travelers find their boarding gates and keep its floors clean as the country prepares for its first Winter Olympics game.

Starting this month, Troika, a self-driving robot made by LG Electronics, will rove the Incheon International Airport, telling travelers how long it takes to get to boarding gates and escorting them to their flights. A jumbo cleaning robot will help cleaning staff swab the wide expanses of floors in the airport west of Seoul.

Troika, about the size of a young teen, is equipped with a rectangular display on its front that looks like a giant screen and can show flight information, an airport map and weather data. Its partly rounded head has a flat touch-screen face that displays blinking or smiling eyes or information.

The guiding bot responds to its name.

Travelers can insert their tickets into its scanner to get flight information, and Troika will then ask if they want to be escorted to their gates, warning laggards to "Please stay closer so I can see you."

Troika's debut piqued the interest of many in the airport. Heads swiveled and children approached with curiosity as the 140-centimeter robot with its white body and black screens glided through the terminal.

The airport said that it does not expect the robots to replace human workers, but just to help, especially with overnight shifts and physically demanding tasks.
