OWI Moonwalker II Beginner Robot Kit

Light and Sound! MOON WALKER II has combined the technology of two sensors. A whimsical indication of future trends, MOON WALKER II begins to walk when it detects a change in light intensity or sound commands. MOON WALKER II continues it's four legged voyage until instructed by an internal timer to stop.
This kit presents an engaging oppor-tunity to learn about some of the mechanics, operation and history of robots. When assembled, this robot uses a phototransistor to sense changes in light (such as turning on a lamp) and a condenser microphone to sense changes in sound (such as clapping). It converts those stimuli into electronic signals to power a motor, and MOON WALKER II will walk forward for a preset time.
When it stops, affecting other change in light area light or sound may activate it again. The sensors can be adjusted for different sensitivity levels.
