科学家发明了一套机器人手臂，可以做饭。此外，它们可以洗碗，也可以发现潜在的危险，如火灾。多么棒的发明！
British scientists have invented a set of robotic arms. They can cook meals for you.
The price of the device is about ￡ 10，000. It includes an oven，a hob，a dishwasher and a sink.
Scientists spent almost 18 years developing the hands. Each hand is governed by 24 motors, 26 microcontrollers and 129 sensors. The arms can chop and stir to recreate almost anything you would like to eat. The food may be a simple homecooked supper, or a wonderful dinner designed by a worldclass chef.
The hands move a little slowly. Whenever they aren't busy, they may hang strangely above the work surface. They can imitate human movements such as wiping a spoon on the edge of a pan to prevent drips. The arms will tuck up when not in use，making space for their owners.
People can train the robotic arms to cook their favorite family recipes by showing them a few times while wearing hightech gloves and wristbands.
Users will also be able to “order” dinner on their way home，or breakfast when they wake up, using an app on their smart phones. Choosing recipes depends on the food materials at home. They will also be able to choose dishes based on their nutritional contents.
The cook chef has emergency equipment in case there's a fire. All the things which are possible with robotic hands are possible here. There is no limitation. This invention will create an opportunity for people to enjoy good food at a reasonable price.
