Do you want a pet, but worry about taking care of it? Aibo might be a good choice for you. Aibo is a robot(机器人) dog. It is made by Sony. It isn’t as difficult to take care of as a real pet.

Aibo’s artificial intelligence(人工智能) makes it act like a real dog. It can wag(摇摆) its tail, shake your hand and play a ball. Aibo can move its ears back and forth. It can also blink(眨眼) its eyes. There are sensors(传感器) on Aibo’s head, chin(下巴) and back. When you touch it, it feels comforted(得到安慰的) like a real pet would. Aibo can understand different words, such as “sit”, “stay”, and “come”.

Another interesting thing about Aibo is that it can “learn”. The robot can remember its daily experiences. This helps it build a database(数据库). The robot can “grow” and change itself according to this database. Over time, Aibo can have its own personality(性格). This makes it more like a real pet.

Alexis Lewis is a teenager from the USA. She likes to invent—to think of new ideas for things that no one has made before, and then make them.

Alexis often enters competitions for young inventors. When she was younger she spent time with her grandfather, who made transport for people to go to space. One day Alexis’ mother told her about a newspaper article which explained how difficult it was to get sick people through the countryside to hospital in Africa. Alexis wanted to help.

Alexis knew that in North America, before there were cars, horses pulled heavy things on a travois(旧式雪橇) made of wood. Alexis thought people could do the same, but she added wheels. To make her travois light, she used bamboo, a plant which grows in Africa, not wood.

To pull Alexis' travois, you wear a belt, which means you can carry or hold other things. Alexis thinks her travois might be useful for carrying food home from the market, as well as taking people to hospital. Now it's finished, she's writing instructions for building one so people in Africa can make it themselves.

With help from US companies, Alexis plans to give ten travois free to hospitals in Africa. She doesn't want money for them because they are for poor people.

Alexis doesn't know if she wants to be an inventor when she's older, because she also likes music and writing, but she thinks it's important for children to learn about inventing at school.
