In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.

Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating (°¤´ò) and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.

Until now, even the most advanced (ÏȽøµÄ) robot was almost certain to break down when it was damaged. That is because its computer inside simply doesn¡¯t know how to make the machine work after its shape has changed.

To deal with this problem, the scientists put eight motors (·¢¶¯»ú) and two sensors (´«¸ÐÆ÷) that read how the machine is working. They all give signals to the machine¡¯s software. Using this information, the computer can then figure out the machine¡¯s shape at any moment.

The new technology is a big advance in robot-making, scientists say, and it¡¯s far from scary. It may someday help scientists create better artificial (¼ÙµÄ) arms and legs and give new freedom to people who losethem. It might also help scientists understand how people and animals figure out their own sense of place in space.

¡°It has been difficult to design robots that can work well when the environment changes or when it¡¯s damaged,¡± says Olaf Sporns of Indiana University in US. ¡°With this work, we are nearer to solving this problem.¡±
