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(挨打) 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(先进的) robot was almost certain to break down when it was damaged(毁坏). 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(发动机) and two sensors(传感器) 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(假的) arms and legs and give new freedom to people who lose them. 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.”

How was your Children’s Day? What kind of gifts did you get?
Eight third graders in some poor places in Hebei Province got new schoolbags as Children’s Day gifts. They were very happy. There were pencils, pens, exercise books and many other school supplies in the schoolbags.
These schoolbags are from students in Beijing Zhongguancun Fourth Primary School. They are in Class 5, Grade 3. They raised money by themselves. They printed out their writings. Their head teacher Mrs Hou helped them to make books. They sold the books at their school to make 800 yuan.
Chen Hongsheng, 9 years old, is one of the students. “We use 800 yuan to buy eight schoolbags at the post office. The post office workers give us a list of the kids. These kids live in poor places. We can choose eight kids by ourselves and post these schoolbags to them,” she said very proudly. “These schoolbags are gifts of our class. This summer vacation, I’ll send out a schoolbag by myself. I hope the kid with my schoolbag can go to school happily like us in the new term.”
