Robots, especially humanoids, are expected to perform
human-like actions and adapt to our ways of communication
in order to facilitate their acceptance in human society.
Among humans, rules of communication change depending
on background culture: greetings are a part of communication
in which cultural differences are strong. Robots
should adapt to these specific differences in order to
communicate effectively, being able to select the appropriate
manner of greeting for different cultures depending on
the social context. In this paper, we present the modelling
of social factors that influence greeting choice, and the
resulting novel culture-dependent greeting gesture and
words selection system. An experiment with German
participants was run using the humanoid robot ARMARIIIb.
Thanks to this system, the robot, after interacting with
Germans, can perform greeting gestures appropriate to
German culture in addition to a repertoire of greetings
appropriate to Japanese culture
