A robotic cook: A robot prepared a salad at the opening of Cetibar, a robot kitchen at the Dresden University of Technology (德累斯顿工业大学) in Germany. This robot, along with many others, helped a star chef in the kitchen. While the chef created the dish, the machines prepared, decorated, and served it. The chef explained that when robots take over the repetitive (重复的) cooking tasks, he can have more time for creativity. Instead of replacing chefs, such robots were designed to support them when there is a shortage of skilled workers.
