“…Instruments for r-service quality measurement have to vary and are contingent on specific service industries and service types. In general, dimensions of r-service quality in the reviewed studies, except for the common dimensions mentioned above, can be subdivided into three categories: i) robot-related component, such as sociability [36], social attraction [36], autonomy [70], safety [70], animacy [69], likability [69], imitation [70], and benevolence [43]; ii) functional component, such as understanding [43], performance efficacy [3], interactivity [11][31], and scalability [70]; iii) consumer-related component, such as perceived safety [69], entertainment [11], and enjoyment [25]. Note that the common dimensions could be utilized as a starting point for instrument development of r-service quality.…”
