Digital module after installation roboplatformu, keeps it on the line while moving forward. The structure of the digital module includes the following functional units: a memory element in the trigger, PWM variable speed motors, adjustable brightness infrared LED, a differential controller sensitivity phototransistor circuit active engine braking. Memory element to trigger remembers the direction of descent and produces a correction signal to the engine in a direction opposite way down the line. PWM controller allows you to change the speed of movement of the robot in a wide range from minimum to maximum. This regulation provides an opportunity to choose the optimum speed required for the sustainable movement on the highway. Tuning adjustment of brightness infrared LED can be set to the sensitivity of the phototransistor of the reflected radiation. Differential regulator allows to equalize the sensitivity for both phototransistor, so the robot to react properly without the "distortions" in the sensitivity of a phototransistor. Scheme of the active brake instantly stops one of the motors provided that the corresponding phototransistor is on the black line. The active inhibition prevents idling engine and the opportunity to go a robot from the line of inertia.
