B 2020河北唐山市高三一模Robots pering tasks according to a predetermined 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 website YouTube, chances are that it will be used by a robot. University of Maryland’s professor Yiannis Aloimonos, leader of the group, said “ There exists a large amount of video ination on the Internet that our robots can capitalize_on．” “ At present, the videos are fed electronically，”said research scientist Cornelia Fermuller. “Originally，we took our own videos, our cameras looking at us doing the cooking，” she explained. “ And, as the robot advances, it reacts to good quality videos.And it will react to even lower quality homemade 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 how to understand a video when it can easily follow a fixed program Aloimonos 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 socalled feedback反馈意见；
another is the introduction of language. “I believe it will take quite some time before the robots are able to understand metaphorical 比喻性的 language，” he added.“ But，” he said, “we don’t need that to create a new world where the robots will be working for us.” 【解题导语】 机器人按既定指令完成任务并不让人觉得新鲜，但能看着视频学做饭的机器人，你可能前所未闻。

catch sight of “看到”。
