Seongnam said in a statement on November 16 the smart library robot equipped with light detection and ranging (LiDAR) sensors will be demonstrated in December 2020. The autonomous library robot that is about 1.8 meters long will also use global positioning system (GPS) signals to find its whereabouts. A LiDAR sensor uses laser beams to measure the distance between the sensor and its target object. The demonstration of the librarian robot received a green light from South Korea's trade ministry to be exempted from regulations on November 15, 2021.
Through the demonstration scheduled to start on November 19, the librarian robot will travel back and forth on a 180-meter-long walking track in Tancheon riverside park. Citizens use the riverside park to walk, exercise and enjoy the rural atmosphere in the city. A person who has Seongnam Public Library's membership card can borrow two books at a time. Books have to be returned to retrieval boxes installed on the park's walking track within two weeks.
Various companies including Naver Labs, the robot and autonomous technology wing of South Korea's top web portal operator Naver, participated in the development of the librarian robot. In 2017, Naver Labs developed "Aircart," a robot handcart that helps people carry heavy objects. The robot handcart detects the movements of operators with sensors installed in its handle. "We plan to operate the robot in other regions after completing the demonstration. The official service will start in March 2022," an unnamed Seongnam official was quoted as saying.
South Korea has accelerated the adoption of autonomous service robots in various sectors. "Dilly Tower," an autonomous service robot developed by the operator of South Korea's top food delivery service app Baedal Minjok, is used to deliver drinks and snacks because it can travel between floors using elevators. South Korea's major telecom company KT is also operating an autonomous concierge robot called "N bot" at a hotel in Seoul to deliver food and amenities. LG Electronic's guide and cleaning robots were deployed to Incheon International Airport, South Korea's main gateway, in 2017.
