Pathfinder Robot Kit 'Blinky'

This amazing robot sees and follows a straight or curved path YOU make with a black marker or tape. Make the path as simple or complex as YOU want. The infrared emitter and light sensor circuit controls a servo feedback loop causing the motors to make course corrections: red and green LEDs blink to display changes in direction. Principles of electro-optics, analog & digital circuitry and more are covered in the 28 page Instruction Manual. Illustrated assembly instructions, many schematic & block diagrams, quiz and troubleshooting guide complete the Manual. Requires one 9V and two AA batteries (not included).
