“…Each of the examined social robots has unique behaviours that change according to their usage areas. Some of these robots behave as companions at home and help people in their daily routine work, such as NAO (Cao et al, 2018), Travis (Birnbaum et al, 2016), Zenbo (Chen et al, 2018), Jibo (Guizzo, 2016), Robovie (Kahn et al, 2008) domestic robots (Xiong et al, 2009), Maggie (Salichs et al, 2006), a small window-cleaning robot (Liu et al, 2009), Buddy (Potnuru et al, 2016), Reem-B (Téllez et al, 2008) and ASIMO (Okita et al, 2009). Some of them look like toys and tell stories, recognize other people, communicate and play games.…”
