In prototype #1 and #2 the behaviour of the robot was implemented by a "finite state circuit" that was equipped with tilt switches and logic gates. In prototype #3 (2006) this circuit is replaced by a micro-controller. Its behaviour is no longer solely reflex based but the robot is also able to perform spontaneous actions when it feels safe. The motion possibilities are increased, which in turn generate more pleasurable feelings.
