Robots performing tasks according to a predetermined(预先设定的) set of instructions are nothing new. But robots able to learn how to cook by watching videos are a completely different approach, which is conducted by a group of researchers at the University of Maryland.

If you have posted a video of your favorite recipe on the popular web site YouTube, chances are that it will be used by a robot. University of Maryland professor Hyannis Alimonies, leader of the group, said "there exists a large amount of video information on the Internet that our robots can capitalize on. "

"At present, the videos are fed electronically," said research scientist Cornelia Ferule, "Originally, we took our own videos, our cameras looking at us doing the cooking." she explained. "And, as the robot advanced, it reacted to good quality videos. And it will react to even lower quality home-made videos. "

So far, the robot named Julia can make a simple salad by breaking each task into basic parts, such as grasping a spoon, bringing it to the bowl, stirring the salad and observing the results.

But why teach a robot to understand a video when it can easily follow a fixed program? Alimonies believes predetermined instructions lack flexibility. He thinks one of the problems is how to make the robot understand and use what it learns during a certain task, the so-called feedback(反馈). "I believe it will take quite some time before the robots are able to understand metaphorical(比喻的) language," he added. "But," he said, "we don't need that to create a new world where the robots will be working for us. "
