In Journey to the West, the Monkey King often turns into a bug and spies on monsters. Today, scientists are trying to turn the story into reality by (make) robot bugs. Would you like to know what they (be) like?
Robot bugs are small robots that (look) like bugs. People can use them (take) pictures in dangerous areas, follow bad guys, or help find survivors (幸存者) in broken buildings.
Work on robotic bugs (start) since World War II. Today they have been greatly improved.
Harvard University scientists have made a very small robot that looks like a fly. It weighs just 65 milligrams, or a little more than the plastic head of a push pin.
What gives power for the robot to make it (fly)? This is a problem. It can only fly when it is connected to a wire that gives power.
Scientists (try) to turn real bugs into robots in other ways these days. US scientists have put computer chips into moths (飞蛾) so people (control) them.
But sometimes these robots (be) in danger. They can (eat) by birds. Other times they can be caught in spiders' webs.
