Scientists at the University of Liverpool (UL) have developed a robot that can run experiments on its own. It's not new for labs to use robots. But earlier robots usually stayed in one place and (do) one job over and over again. The UL robot is different. It's able to (easy) move around in the same kind of space as humans do. It uses a special system called LIDAR to guide (it). With one long arm which can turn in almost any direction, the robot can use several different kinds of lab equipment and carry out variety of tasks.
The scientists say it took a lot of work (program) the robot so that it could do things without (make) mistakes. Once the programming is done, though, the robot makes (few) mistakes than a human.
To test their robot, the scientists gave it a task: find a material was able to produce hydrogen (氢) from water. The robot was programmed to understand the basic methods for the experiment, but it (give) 10 different things it could change which could influence the results. That meant that the robot could choose from around 98 million different mini-experiments. Over the next 8 days, the robot ran 688 experiments, always choosing its next experiment based the results of the last one.
