Start brushing on the top of your mouth on one side, but don’t brush too hard.

>>RACHEL: It’s Robot week, and tonight we've got more - WHAT'S THAT SOUND?
[WHATS THAT SOUND THEME]
>>RACHEL: Tonight’s sounds are made by tools that robots use.
Here’s your first one:
[ELECTRONIC, ECHOEY BEEPS]
>>RACHEL: Here it is one more time:
[ELECTRONIC, ECHOEY BEEPS]
>>RACHEL: What type of technology makes that sound? Shout it out:
>>GROUP: Sonar!
>>RACHEL: Switch your brushing to the other side of the top of your mouth…
[SWITCH BELL]
>>RACHEL: -and keep on brushing.
Sonar is a technology that uses sound to sense where objects are located. When a machine sends out a sonar sound, the sound bounces back, or echos..
[ECHOEY EFFECT]
>>RACHEL: telling the machine that there’s something nearby. So scientists have created underwater robots that use sonar to check out shipwrecks and map the ocean floor.

[LENS SHUTTER]
>>RACHEL: So what’s that sound??

Switch to the other side of the bottom of your mouth.
[SWITCH BELL]
>>RACHEL: Robots use sensors to get a sense of the world around them. Cameras are a type of sensor used by robots to help them see. Flying robots called drones use cameras to help humans see from way up in the sky…
[HELICOPTER SOUNDS]
And self-driving cars use cameras and other technology to figure out where to go.
