Ultrasonic Sensor
Ultrasound is a type of sound with a frequency bigger than humans can hear. This frequency, the 'upper-limit of human hearing,' is approximately 20,000 hertz (20 kilohertz). Bats use the type of sound to find objects. Your robot can do that too. Like bat it can also find out how far away something is.
