√ Does it explain the advantages and disadvantages of the career clearly
2. Get the students to recommend a few interesting letters to share in the class.
Step 2 Video Time: Flight of the RoboBee
Activity 3 Pre-viewing
1. Lead in the topic by introducing what is RoboBee.
RoboBees are small flying robots (drones) that are being developed at the Wyss Institute of Harvard University by a team headed by Robert wood.
2. 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. You can use the context information, background information and common knowledge.
Activity 4 While-viewing
1. Watch the video for the first time to check your predictions and complete part of the quotes by Robert Wood. (Tips: Go through the sentences first and predict what words may be used in blanks. When taking notes, first write down the key words, and then add more information while viewing the video for the second time. )
Answers:
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. Watch the video again to complete the quotes by Robert Wood, take notes and the check the answers.
Answers:
1) ... robotics is the next Internet. It’s the next big thing to impact our lives in areas from medicine to even things like space exploration.
2) We use nature to inspire the robots that we build.
3) ...they can be quite useful for applications where you wouldn’t want to put a human or an animal...
4) If you don’t fail, you don’t learn enough.
5) If you want to make something fly, a solution already exists in nature.
3. Watch the video once more to understand it better. Reconstruct the text by summarizing the main content of the video.
Activity 5 Post-viewing
Discuss these questions in groups and share the answers.
Suggested answers:
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. Specifically, 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
A robotic spider could be useful as it could carry things across difficult uneven surface where wheeled vehicles can’t go.
