Collaborative robots, which can combine the advantages of robotic automation with the flexible thinking capabilities of human workers, are emerging as a solution to these problems. Owing to the growing importance of collaborative robots, the International Organization for Standardization (ISO) has published standards for industrial collaborative robots, such as ISO 10218 and ISO/TS 15066. Although the requirements for robot operation in a collaborative environment between a collaborative robot and a human operator have been presented, most of the proposed standard clauses present technical requirements in terms of system performance. 

With the increasing use of collaborative robots in various fields, it is essential to verify whether these robots satisfy the required QoE standards. However, existing QoE assessment standards for collaborative robots often fail to consider user-centered design requirements, particularly when considering the dynamic characteristics of user needs. In this research, we aim to design QoE assessment criteria for collaborative robots based on a user-centered design framework. The design of user-centered ergonomic standards for collaborative robots to secure the technology acceptance and trust of human workers can be revived according to the needs of workers to prepare actively and efficiently for changes in the international business environment.
