¡¡¡¡Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired£®The walk to school would be very ,very easy£®Such supercharged 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 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£®

¡¡¡¡¡°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(ÏðÊ÷ÁÖ¹ú¼ÒʵÑéÊÒ), US£®While these suits are at least ten years away, in some areas the technology is already in use£®

¡¡¡¡Researchers are developing artificial arms and legs that allow old, disabled or injured people to move freely£®Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle£®Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier£®

¡¡¡¡A robot is a device that responds to a command£®You're probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control£®

¡¡¡¡Wearable robotics goes further£®Instead of just receiving information through a wire or remote control, the robotic device can send information back to its controller£®

¡¡¡¡Suppose you wore a sleeve that has sensors where your joints 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£®
