Small bug has big power 

The next time you feel a bug crawl (爬行) across your skin, don't be frightened. It might just be a tiny robot crab (螃蟹)! Engineers from Northwestern University in Illinois, US, have developed the smallest ever remote-controlled walking robot, and it comes in the shape of a tiny, lovely crab.

Just half a millimeter wide, the crab can bend, crawl, walk, turn and even jump, reported Science Daily. The team of Northwestern University believes that their technology is a big step closer to bringing about robots that can do remote-controlled work in tiny spaces. For example, the tiny robots can help clear people's clogged arteries (堵塞的动脉) in surgeries (手术), said John A. Rogers, who led the team.

Who's riding these camels? Little robots! They are having a race in Abu Dhabi, United Arab Emirates (阿布扎比，阿联酋). Camel racing is popular in the country. But for human riders, it can be dangerous. Robots are here to help. The robots are small and light. They won't affect the camels' speed during the race. The robots use whips to make the camels run faster. People control the robots by using speakers (扬声器) placed on the robots.

Newspaper ‘hires robot writer'

What would you think if this story was written by a robot? Of course, this one was not. But a recent story in the Los Angeles Times was. It's a newspaper in the US. The story is about an earthquake in the US on March 17. The newspaper was using a system that can automatically (自动地) "write"a short story when an earthquake hits. It took about three minutes for the 102-word story to appear online.
