This amazing robot uses its electronic brain to follow or find a light source (such as a standard flashlight). Using its drive motors, the Light Spider will scoot across any smooth hard surface (such as a linoleum floor or a wooden table top) looking for light. Unlike “normal” spiders that hide in the dark, our Light Spider robot actively searches for light! While searching, a LED array on the front of the robot lights up and blinks. The Chaney Electronics Light Spider Kit offers a great experience for your students as it is easy to build and fun to watch as it searches for light. It is an economical addition to your curriculum and your students will be amazed at the Light Spider's ability to follow light. We are proud to offer you this quality robot at such an affordable price. Those that have had the opportunity to control the Light Spider have been amazed at how well it responds and how much fun it is to play with. We used a flashlight to control the movements of our Light Spider - Look below for a video clip of this kit in action.
