This study was designed in order to examine how to form behavioural intentions using the technology acceptance model (TAM) and the theory of planned behavior (TPB) in the context of robotic restaurants. In particular, this research proposed that perceived ease of use positively affects perceived usefulness, which thereby exerts a positive influence on attitude. In addition, subjective norm was hypothesised in order to facilitate the enhancement of attitude and personal norm. Lastly, attitude, subjective norm, perceived behavioural control, and personal norm were proposed to play important roles in the formation of behavioural intentions. The data was collected from 416 respondents in South Korea. The data analysis results showed that all the hypotheses within the model that merged the TAM and TPB were statistically supported.
