Robot services have become an essential competitive differentiator in the hospitality and tourism industry. Seminal studies indicate the need for more profound knowledge about the factors that can increase the acceptance of service robots. This paper investigates the relationship between informational cues and acceptance of service robots through a meta-analysis. Our study also analyzes the acceptance of service robots through contextual characteristics moderators. The results showed that perceived robot trust influences the relationship between informational cues (anthropomorphism and social influence) and acceptance of service robots. By analyzing previous studies, our framework demonstrates that acceptance of service robots has increased more after the COVID pandemic than before the COVID pandemic. Furthermore, the relationship between attitude toward robots and robot usage intention tends to be greater in humanoid service robots (than social robots) and analytical intelligence (than mechanical intelligence).
