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.
