Ultrasonic sensors: purposes
Ultrasonic sensors will enable your robot to detect obstacles and assess how far away they are.
Ultrasonic sensors: directivity
The directivity of ultrasonic sensors is very reliable.
Unlike infrared sensors and lasers, ultrasonic sensors have a relatively wide cone angle.
The measurements they take become less precise as the distance between the obstacle and the robot increases; although ultrasonic sensors have a shorter range than lasers, it is longer than that of infrared sensors.
