PHOTO Robot takes charge of royal palace patrol

A patrolling robot named Sullabot roams around Changdeok Palace in Seoul, Friday. According to the Korea Heritage Service, the pilot project is aimed at addressing blind spots in palace management. Sullabots will be used until March 9, after which authorities will decide whether to keep them permanently. The word "sulla" refers to soldiers patrolling the palace walls during the Joseon Dynasty (1392-1910). Yonhap
