LEGO® Mindstorms Vision Command (RCX Digital Colour Camera) 9731

Build robots that respond to what they see! Vision Command, featuring the new LEGO Cam, lets you program anything from a motion sensitive spy camera to a music synthesizer that you can play with a wave of your hand. When combined with Robotics Invention System (LEGO set 9719, 9747 or 3804), Vision Command becomes a revolutionary vision sensor smart enough to be the eyes and brains of your robot. Explore the latest in robotics technology! First, program your PC to react to what your camera sees by playing a sound, recording video or taking pictures. Then set your camera to detect changes in motion, color or light. Finally, click "run" and watch as your camera does things such as playing musical notes at the wave of a hand, sounding an alarm when an intruder enters your room or recording a video of anyone taking your favorite blue t-shirt!
