The sensor/servo board mounted in the head has been split into two boards. This has allowed the number of servo channels to be expanded to ten and the number of sensor channels (petting zones) to be expanded to twelve. The prototype petting zones now have LEDs built into them so they react instantly when touched, providing people with immediate feedback to show that their petting is being registered by the Raffe. Previously it could be difficult to tell because many people could be petting the Raffe at the same time, but of course it will only speak one sentence at once in reaction.
