Reading and speaking
Our design team is planning a library helper. The robot will be eighty centimetres tall. It will carry only a few light books at a time and will not use stairs. We might power it with a rechargeable battery. A large stop button will be easy to see. If the path is blocked, the robot will stop and wait for a person. We compare it with two larger plans, but we do not call it the best just because it is the smallest. We will also reuse a clean box for the display model. The design is an idea, not a finished machine.
