Abstract: The rapid development of artificial intelligence technology and the ethical needs of family life have opened up a realistic channel for the family application of artificial intelligence. However， the ontological distinction between emotional privacy based on biological characteristics and technical publicity based on data algorithms makes the dilemma of fusion of technology and ethics prominent in the family field. From the practical level of technical application， the ethical application of artificial intelligence in the family requires the participation of multiple perspectives such as engineers， ethics reviewers， and family members. From the perspective of ethical thinking， the possible situations such as the invasion of computationalism into the emotional realm， the compatibility dilemma between machine metaphors and family metaphors， and the “collapse” or “new model” of the relationship between individuals and entities cannot be ignored. Considering that the family intervention of artificial intelligence may change the existing form of family ethics， to answer whether artificial intelligence can provide ethical support for the family， a conservative position that is alert to the changes of ethical subjectivity is needed.

Key words: artificial intelligence; social robot; emotional interaction; family ethics; ethical support
