LOOKING INTO THE FUTURE
To learn to predict what you may watch by reading questions or statements before watching;
To learn to take notes while watching;
To talk about your opinions on advantages of small robots over large ones;
To talk about other robotic creatures.
Flight of the RoboBee
RoboBees are small flying robots that are being developed at the Wyss Institute of Harvard University by a team headed by Robert wood.
What are RoboBees possibly used for
Before You Watch
Predict what you are going to see. Think and circle the correct word(s) for each sentence.
Tips: Read questions or statements before watching a video. It’s helpful for us to guess what we may watch in the video.
1. RoboBees are like bees in that they fly independently / together, but all work independently / together.
2. Robert Wood is an explorer / a roboticist.
3. In the future, RoboBees could help explorers / policemen and doctors / photographers.
4. All of the RoboBees have crashed / flown successfully.
5. Like bees, every RoboBee has a job to do / obeys a queen bee.
While you watch
Check your answers in Before You Watch.
1. RoboBees are like bees in that they fly independently / together, but all work independently / together.
2. Robert Wood is an explorer / a roboticist.
3. In the future, RoboBees could help explorers / policemen and doctors / photographers.
4. All of the RoboBees have crashed / flown successfully.
5. Like bees, every RoboBee has a job to do / obeys a queen bee.
2. Complete the quotes by Robert Wood with words you hear in the video.
1. ... robotics is the ___________. It’s the next big thing to ______________ in areas from medicine to even things like _______________.
2. We use nature to _______________ that we build.
3. ...they can be quite useful for applications where you wouldn’t ___________________ or an animal...
Tips:
Go through the sentences first and predict what words may be used in blanks.
next internet
impact our lives
space exploration
inspire the robots
want to put a human
4. If you don’t fail, you _________________.
5. If you want to make something fly, _____________________ in nature.
don’t learn enough
a solution already exists
After you watch
Discuss these questions in groups.
1. What might be some advantages of having many small robots that work together rather than one large robot
A large robot often takes up too much space and has difficulty in moving. Small robots working together can easily enter a small space and move around.
2. Specially, how might RoboBees be used in a future application
They might be useful in rescue after a disaster. For example, if a building was blown down in a storm, they could fly into the wreckage and check for survivors.
3. What other kinds of robots can be created from nature (e.g. a robotic lion or snake) How might these robots be used
Think about the following things.
what it is used for
in what shape it is suitable for the use
...
Write a passage and try to describe a ideal robot in the future. You can describe its appearance, features, working places, functions, etc.
