Today, robots come in all shapes and sizes. They can’t complain, even if the work is heavy and dangerous. And they can work or play all day without getting bored. Unlike a human’s arms, a robot’s joints will never get stiff (僵硬的). The end of the arm can be fitted with devices (装置) to perform different tasks. These could be a welding (焊接) point, suction cups (吸附杯) or gripping fingers (钳形指) for lifting and moving objects. Such an arm of these computer controlled industrial robots can work 24 hours a day.
Robopets (机器人宠物) are high-tech robots programmed to play. They can communicate with their owners and recognize their voices. Each one will develop a different “personality”. They can be a lot of fun to play with, but these robots can also be helpful to people who are sick and can’t look after a real animal. Many doctors believe that when a person is happy and laughing, their body recovers faster. A robopet might be just what the doctor ordered.
NeCoRo is a robot cat that has been developed to be more than a toy. The robot uses sensors (传感器) that can detect movement and sound. It can even store helpful information in its memory. Its behaviour changes over time, just like a real pet.
