Article: After record increase in over 40 countries, Universal Robots' lightweight robotic arms are now making their US debut at this year's International Manufacturing Trade Show (IMTS) in Chicago. The UR5 robotic arm made by Universal Robots has been announced officially "The world's most innovative robot" by The International Federation of Robotics and IEEE (Institute of Electrical and Electronics Engineers) Robotics and Automation Society. The US audience will now see the award-winning robot -- along with its big brother UR10 -- for the first time. The UR5 and UR10 robotic arms are aimed at small-sized companies that thought robots were too expensive and hard to operate in existing production. The robotic arms are easily moved around the production area and present a simple user interface which lets workers quickly operate them. Esben Ostergaard, founder and CTO (Chief Technical Officer) at Universal Robots, explains how the robots were designed to be as user--friendly as possible: "We decided to make programming easy by developing a user interface worked together with a "teaching function" allowing the user to simply took hold of the robot arm and show _ how a movement should be done. The robot can work in any production process very quickly. Our experience shows this is generally done in a few hours." The robots weigh as little as 40 pounds, making it possible for them to be moved around the production area to do different tasks. The UR5 can handle a load of up to 5 kilos (11 pounds), the UR10, 10 kilos (22 pounds). As soon as a worker touches the robot arm and uses a force of at least 150 Newton, the robot arm will automatically stop operating. Question: What's the text mainly about? - An introduction to Universal Robots' new robots. - The difference between the UR5 and the UR10. - Why the UR5 and the UR10 were invented. - How to operate the UR5 and the UR10.

Read the following article and select the best answer. Article: The nation's largest group of pediatricians on Monday urged its members to "firmly oppose boxing for any child or adolescent." In a statement, the American Academy of Pediatrics (AAP) said thousands of boys and girls take part in the sport in North America, despite risks of serious brain and facial injuries. The group's position was approved by some experts. "There is very little one can do in order to increase the chance of having a healthy brain when you get old," said Dr. Hans Forstl, who has studied boxing injuries. " One of the best things you can do is avoid boxing." He said. According to the new statement, published in the journal Pediatrics, information from Canada shows a rise in boxing injuries over the past decade. Pat Russo, a retired police officer who runs a boxing gym in Brooklyn, New York, said injuries are rare in amateur boxing. After 26 years and training thousands of kids, he has seen just one split lip among his students. " If the gym is run properly, injuries are at an absolute minimum," Russo said. "Football is ten times more dangerous. While tennis or football might also help kids gain confidence, boxing holds a special attraction for children in poor neighborhoods, because it allows them to act tough while in trouble." Dr. Robert Cantu, a surgeon at Emerson Hospital in Concord, Massachusetts, said AAP's attitude makes sense for upper-class and middle-class kids. " Clearly boxing is safer today than it was 20 or 30 years ago, but it is still a very risky activity," he said. "For kids in poor areas, however, the situation is different," said Cantu. " The most dangerous thing for the majority of people in boxing is just where they live. They are far safer in the ring , even taking blows to the head, than they are out in the neighborhood."
