Intro

As you have already seen from the title, today’s lesson will be about ultrasound. Prepare to have a discussion with your teacher.

• What is ultrasound??
• What are the applications of ultrasound?
• Is it possible for robots to navigate using ultrasound?
• How bats see in dark?

Before we start with the ultrasonic sensor, let's take a look at few support wheel constructions first. Have each team in the room build a different support wheel and then you can swap them out.
