An Affective Model Applied in Playmate Robot for Children

It is always the focus of researchers' attention to endow the robot with the emotion similar to human in human robot interaction. This paper present an artificial affective model based on Hidden Markov Model (HMM). It can achieve the transfer of several affective states under some basic hypothesis and restriction. The paper also shows some simulation results of affective states change. It is the basis for architecture in support of interactive robot. Then the paper explains the technical route of playmate robot for children in detail. The robot can behave like a human child and attempt daily communication with human supported by the affective model and these technologies.
