52至54題Robots are already entrenched and spreading fast in the industrial sector. Fromdriverless cars to delivery drones, a new generation of robots is about to revolutionize the way people work, drive, and shop. They have been the subject of popular imagination for decades. However, many experts worry about the dangers that robots pose to the humans who work alongside them.Robots have caused at least 33 workplace deaths and injuries in the United States in the last 30 years, according to data from the Occupational Safety and Health Administration. For example, at a car factory in 2006, a robot caught an employee on the back of her neck and pinned her head between itself and the part she was welding. She was killed. In 2001, an employee was cleaning at the end of his shift and entered a robot's unlocked cage. The robot grabbed his neck and pinned the employee under a wheel rim, asphyxiating him. Though regulations have required that the robots operate separately from humans, in cages or surrounded by light curtains that stop the machines when people approach, most of injuries and deaths have happened when humans violate the safety barriers. The number of deaths may not sound like many, but it may understate the dangers ahead.Robots have long toiled in factories and warehouse, where they load boxes with items, drill and weld car parts, or move food from one conveyor belt to the next. Unlike today's robots, which generally work in cages, the next generation will have much more autonomy and freedom. They will collaborate with humans and travel freely in open environments where people live and work. They are products of the declining cost of sensors and improved artificial intelligence.Along with the new robots come new safety concerns. What happens if a robot spins out of control? What about the first time a driverless car kills someone? The new robots require extra protective measures. For instance, Google's driverless car has a padded front to soften any blow in case of an accident. The windshield is plastic, and the front of the car is rounded so it is less likely to hurt or trap pedestrians of cyclists. Still, experts worry that there's something scarier about a machine malfunctioning and taking away control from somebody.
