The walk to school would be very, very easy. Such sophisticated clothing is one of the products that could be created using "wearable robotics"technology. Designed to improve a person's senses and skills, the device (装置) could be as simple as a hearing aid. Or it could be a full-body suit that senses what you're going to do, then helps you do it better. Robot legs help a man carry a heavy load. "A Superman suit would be the final result in wearable robotics, "said Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory (橡树岭国有验室), US. While these suits are at least ten years away, in some are- as the technology is already in use. Researchers are developing artificial arms and legs that allow old, disabled or injured people to move freely. A robot is a device that responds to a command. You've probably played with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control (遥控). Wearable robotics goes further. Instead of just receiving information through a wire or remote control, the robotic de- vice can send information back to its controller. Suppose you wore a sleeve (袖子) that has sensors where your joints (关节) are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action. In this way, scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do. 1. Which of the following can replace the underlined word "so phisticated"in Paragraph I? A. Expensive B.
