How it works
Facing the insufficiency of the ultrasonic distance sensors for the autonomous navigation, we arrived at the next stop - infrared distance sensors.The plan was to build kind of sensors array formed by the numerous distance sensors facing in different directions and saving the robot at least from hitting the obstacles in front and falling down from the height. These sensors must be inexpensive both in terms of money and energy consumption.
Soon we found an interesting option, surprisingly named "Infrared Obstacle Avoidance Sensor for Arduino Robot" - it is precisely what we need!
