The potential of these robots to influence human behaviour and attitudes holds significant implications for fields such as healthcare, marketing, and promoting sustainability. This study investigates how the design and behavioural aspects of social robots affect their ability to persuade, drawing on principles from human interaction to enhance the quality of human\u2013robot interactions. Conducted in three stages, the experiments involved 73 participants, offering a comprehensive view of human responses to robotic persuasion. Surprisingly, the findings reveal that individuals tend to be more receptive to a single robot than to groups of robots. Nao was identified as more effective and capable of persuasion than Pepper. This study shows that successful persuasion by robots depends on social influence, the robot\u2019s appearance, and people\u2019s past experiences with technology.<\/jats:p>","DOI":"10.3390\/info15120782","type":"journal-article","created":{"date-parts":[[2024,12,5]],"date-time":"2024-12-05T08:33:51Z","timestamp":1733387631000},"page":"782","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Impact of Robot Size and Number on Human\u2013Robot Persuasion"],"prefix":"10.3390","volume":"15","author":[{"given":"Abeer","family":"Alam","sequence":"first","affiliation":[{"name":"School of Computer, Data and Mathematical Sciences, Western Sydney University, Penrith 2751, Australia"}]},{"given":"Michael","family":"Lwin","sequence":"additional","affiliation":[{"name":"School of Business, Western Sydney University, Penrith 2751, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7847-6576","authenticated-orcid":false,"given":"Aila","family":"Khan","sequence":"additional","affiliation":[{"name":"School of Business, Western Sydney University, Penrith 2751, Australia"}]},{"given":"Omar","family":"Mubin","sequence":"additional","affiliation":[{"name":"School of Computer, Data and Mathematical Sciences, Western Sydney University, Penrith 2751, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Haring, K.S., Satterfield, K.M., Tossell, C.C., De Visser, E.J., Lyons, J.R., Mancuso, V.F., Finomore, V.S., and Funke, G.J.
