Hyper Line Tracking Robot

This robot possesses photo transistors to detect a black line and two red LEDs that flash to tell you which photo transistor is activated. Hyper Line Tracker follows a course of your own design. By using a light emitter, light sensor circuitry, and its drive motors, it demonstrates how robots ""see"" a pathway. Make a path with a black felt marker or black tape and watch how light sensors enable the robot's motors to make course corrections. Requires four AA batteries (not included).
