Unit 2 Looking Into The Future Video Time P24 Learning objectives: By the end of this period, you will be able to… predict what you may watch by reading questions or statements before watching; take notes while watching; talk about your opinions on advantages of small robots over large ones; talk about other robotic creatures. Lead in Flight of the RoboBee Lead in RoboBees are small flying robots that are being developed at the Wyss Institute of Harvard University by a team headed by Robert wood. What do you think the RoboBees are used for? Discussion 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. RoboBees are like bees in that they fly independently/together, but all work independently/together. Robert Wood is an explorer/a roboticist. In the future, RoboBees could help explorers/policemen and doctors/photographers. All of the RoboBees have crashed/flown successfully. Like bees, every RoboBee has a job to do/obeys a queen bee. Check your answers in Before You Watch. Complete the quotes by Robert Wood with words you hear in the video. While You Watch Tips: Go through the sentences first and predict what words may be used in blanks. 1. ... robotics is the __________.

If you want to make something fly, __________________ in nature. next Internet impact our lives space exploration inspire the robots want to put a human don’t learn enough a solution already exists What might be some advantages of having many small robots that work together rather than one large robot? Specially, how might RoboBees be used in a future application? What other kinds of robots can be created from nature (e.g. a robotic lion or snake)? How might these robots be used? Discuss these questions in groups. A robotic spider could be useful as it could carry things across difficult uneven surface where wheeled vehicles can’t go. 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. 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. After You Watch Thank you! $$
