On Wednesday, July 16, 2008, IFEZ signed a memorandum of understanding (MOU) with the Ministry of Knowledge Economy and SK Telecom to develop a robot service for Tomorrow City. In order to overcome the practical limitations of the HRI (Human-Robot Interaction) function, the robot service will play a role in assisting humans by adopting a hybrid robot service that can be automatically and manually switched and a kiosk collaboration function to guide the exhibition directly.
