Phobot is a small proof-of-concept, affective robot. Phobot is a phobic robot, who's very scared of certain objects, and robots in particular. Phobot is meant as a concept exploring possible support tools for kids with object or location-related phobias. Phobot and the phobic child will help each other overcome fears by following exposure program steps. If you help Phobot out, gradually exposing the little robot to bigger and bigger robots, Phobot will overcome its fears.
Phobot can be scared, curious or a little sad. Phobot expresses emotional by facial expression, a changing heart beat, movement, posture and sound. Phobot recognises scary objects, panics and then needs to be coached to re-approach the object by holding its hand and speaking softly. The child in turn can express his or her emotions to Phobot using a 'fear thermometer'.
The Phobot concept has been implemented using Lego Mindstorms NXT, an additional Codatex RFID sensor and programmed using the Mindstorms software. RFID, sound and touch sensors have been used to achieve interaction with the user.
