In preparation for 2018 Winter Olympics in South Korea, electronics giant LG is trialling new robots in the country’s largest airport. Seoul’s Incheon International Airport is now home to two of LG’s latest prototype bots, the Airport Guide Robot and the Airport Cleaning Robot. The bots were first unveiled at CES earlier this year, and both do exactly what their names suggest. The Guide Robot will roam the terminals, ready to provide travellers with directions and information about boarding times. It speaks four languages Korean, English, Chinese, and Japanese. Users can even get it to scan their boarding pass to be escorted to their correct departure gate. The Cleaning Robot, meanwhile, is essentially a beefed-up Roomba that looks a little like a mini-tank. According to LG, it “detects the areas that require the most frequent cleaning, stores those locations in its database and calculates the most efficient routes to get there.”
