“…As shown in Appendix Table A1, we collected 20 papers published from 2017 to 2020 about user acceptance of service robots. These studies used theories including TAM (Hwa et al., 2018; Saadatzi et al., 2020), UTAUT (Guggemos et al., 2020; Kencebay, 2019), DIT (Khaksar et al., 2019), Attribution Theory (Belanche et al., 2020), Self‐Congruity Theory (Dudek et al., 2020), and Uncanny Valley Theory (Appel et al., 2020). Based on TAM/UTAUT, relevant studies have also created new models, such as RAM (Turja et al., 2019), HRCAM (Bröhl et al., 2019), an AIDUT (Lin et al., 2019).…”
