I show you how I like you - can you read it in my face? [robotics]

We report work on a LEGO robot that displays different emotional expressions in response to physical stimulation, for the purpose of social interaction with humans. This is a first step toward our longer-term goal of exploring believable emotional exchanges to achieve plausible interaction with a simple robot. Drawing inspiration from theories of human basic emotions, we implemented several prototypical expressions in the robot's caricatured face and conducted experiments to assess the recognizability of these expressions.
