Focus on a children-dependent robotic approach to establish asynchronous child assistance with a social rapport network for the purpose of collecting trash from a public space. Indeed, a sociable trash box robot (STB) was unable to collect trash by itself, but it succeeded in conveying its intentions to collect the trash to the children. The main purpose of this study is to investigate the effective social cues, behaviors, and other essential factors to facilitate children in their anticipation of the behavior of a sociable trash box robot (intentional stance). The STB engages using interactive social cues and vocal interactions to build a social coupling with children in order to induce their assistance in collecting trash.
