Through patrol technology, we can control robots or vehicles to move along artificially designed lines automatically. This technology is widely used in the automation industry, such as material turnover of production line, goods transportation of logistics warehouse, and also simple unmanned driving can be based on patrol technology.
Line Finder Card uses infrared sensors to find its way around. By laying white lines on dark ground, several infrared sensors can clearly detect the movement and feed back signals, allowing the robot or car to adjust its direction in real time.
Line Finder Card features MV358 comparator, and it is ideal for building a line following robots. On the back of the Line Finder Card, there are three sets of sensors consists of IR emitting LED and an IR sensitive phototransistor. Each sensor is capable of detecting a black line on the white background or a white line on the black background.
Longan Cards is a unique open source development platform designed by Longan Labs. As a plug and play development platform, Longan Cards allows you to quicky build wide array of prototypes and applications in no time. A full set of Arduino libraries and plenty of example codes are available to play with Longan Cards platform.
