I was sent this link by Carolina Chang from the University Simón Bolívar Caracas in Venezuela. Carolina used this model to introduce her course in robotics. My Spanish is very ropey. (No entiendo, no hablo Espanol is about my limit) but from what I can understand, the computer controlled Agreeable Sheep agrees with everything you say! Speak into the microphone and the sheep nods while her eyes light up mysteriously!
Thanks Carolina, it's fantastic!
