This chapter briefly reviews various ways in which ethics have been implemented in AI-enabled devices such as humanoid and expressive robots, and how care for other forms of embedded AI is an important part of creating trustable and ethical AI systems. We look at nudging in particular, how robots experienced in social contexts could implement nudging, and the implications of nudging for four fundamental ethical values that underpin trust. We discuss this topic using examples and by presenting important questions that creators of AI-based nudging systems should ask themselves, before and after creating such systems.
