1 It is very small and light and can fly
almost anywhere. It has four engines and is called a quadcopter. There is a camera at the front and it is very useful for taking pictures. You can fly it using a smartphone or a remote control unit. TV companies use them to make videos. It’s a lot cheaper than using a helicopter.
2 The idea first started in Japan for
car-making. Now you can find them everywhere, for example, in shops. They are also used for tourist information. They are very useful for getting information about products and places. You scan them with your smartphone and the code will open a page on a website with more information about the product or place you are interested in. They are called QR codes.
3 This is a printer that makes objects in
3D or three dimensions. We can use them to make copies of anything from shoes to food. The information for the object comes from a computer. It is a quick and accurate way of making lots of exact copies of the same object. In the future, we will be able to download products and print them out at home on our own 3D printer.
