We report work on a LEGO robot capable of displaying several emo-
tional expressions in response to physical contact. Our motivation has been
to explore believable emotional exchanges to achieve plausible interaction
with a simple robot. We have worked toward this goal in two ways. First,
acknowledging the importance of physical manipulation in children's inter-
actions, interaction with the robot is through tactile stimulation; the various
kinds of stimulation that can elicit the robot's emotions are grounded in a
model of emotion activation based on different stimulation patterns. Sec-
ond, emotional states need to be clearly conveyed. We have drawn inspira-
tion from theories of human basic emotions with associated universal facial
expressions, which we have implemented in a caricaturized face. We have
conducted experiments on both children and adults to assess the recogniz-
ability of these expressions.
