What is the purpose of the robat? (answer in at least 1 complete sentence and use information from the text - but don't copy and paste!)

Choose the correct THREE objectives the Robat can complete

• It can map an area

• It can recognize obstacles

• Identify obstacles in its' path

• It can pick up objects

• It can fly and drive on land

Find the section of the article about artificial neural network. According to the article with what accuracy can Robat identify objects?

• 20%

• 40%

• 70%

• 90%

Summarize the last section of the article, "What Did We Learn Thanks to the Robat, and Why Being a Bat is Hard?" in your own words:

Use 3-4 sentences

Which of these statements is NOT an improvement the researchers plan to make to the Robat design and operation?

• add ear-like receivers

• improve object identification

• better algorithm to move around obstacles

• make it a flying robot.

• increase the battery life

Match the following

• Artificial Neural Network

• A computer program that simulates brain activity because it is made from many sub-units (like brain cells) that communicate with one another. These programs are shown many examples of a certain input, such as a certain picture or sound—and they learn to recognize it and differentiate it from other inputs.

• Echolocation

• Perceiving the world by emitting sounds and analyzing the returning echoes. The sense is used by bats and toothed whales but humans can also receive echoes and some blind people use a simpler form of echolocation.

• Ultrasonic Frequencies

• Very fast vibrations of sound that cannot be heard by the human ear
