In this study, we have developed a prototype of a status indicator (light) suitable for Foodly,'' which is a collaborative robot that works alongside people in the process of serving lunches in a food factory. In order for the robot to work with people, it must have a non-fearful, non-intimidating appearance and a display that can provide safety and operational information appropriately. We built several prototypes and compared their appearance. We determined if the information provided could be properly understood. We classified the safety information into four categories, which can be easily recognized by users from safety and operational perspectives.
