It will also help you to decide what you will need to build into a machine before it can be considered as a robot. A robot has these important characteristics.
Sensing First of all, your robot would have to be able to sense the environment around it.
Give your robot sensors (传感器): light sensors( eyes ), touch sensors (hands), chemical sensors(nose), hearing sensors(ears) and taste sensors (tongue).
Movement A robot needs to be able to move around its environment. It can move on wheels, walk on legs or be driven by small engines(发动机). A robot can move either the whole body or just parts of it.
Energy A robot needs to be able to power itself. Some robots might power itself with sunlight, some might with electricity, while others with the battery(电池). The way your robot gets its energy will depend on what your robot needs to do.
Intelligence A robot needs some kind of "smarts". A programmer is the person who gives the robot its "smarts". The robot will have to have a certain way to receive the program so that it knows what it is to do.

Save energy and water! ◇ Before leaving home, make sure to turn off the electricity. Take great effort to develop wind power and so on. ◇ If you can, try bicycling, walking, or using public transportation to get out instead of using the car. ◇Don't let water run while brushing your teeth and take short showers of four minutes or less. | Be a pioneer! ◇ Share your knowledge with others and help them become eco-heroes too. It takes lots of people working together to make changes happen. So share, share, share. ◇ Volunteer with more friends. Write to some companies to stop them working together with people who are harmful to the forest. |
Reduce, reuse, and recycle! ◇ Before you throw something away, stop and think about what else it could be used for. ◇ If you don't want to keep some things, try to find out who else needs them. Our goal is to keep usable things out of landfills (堆填区). | Be friendly to wildlife! ◇ Make your garden wildlife-friendly. You could build a bee hotel, provide some food, or even create a pool. ◇ If you own a cat that goes outdoors, put a bell around its neck so that little wildlife can hear it coming and run away quickly. |
