-Robots often need to sense the environment around them, particularly when driving autonomously.  Ultrasonic sensors are like the sonar used by bats.  They emit a chirp of sound and measure the time it takes to hear an echo of that chirp.  The longer the time, the further the sound traveled.  Since sound travels at a particular speed through air, we can use the echo delay to calculate how far away the object was that reflected the sound.  You can read more about ultrasonic sensors [https://wpilib.screenstepslive.com/s/currentCS/m/java/l/599715-ultrasonic-sensors-measuring-robot-distance-to-a-surface here]
