roach robots to the rescue\nwhen buildings collapse, it is extremely difficult to safely locate and rescue people trapped inside. victims may be wedged into small spaces, and unstable rubble could collapse on rescue workers. an alternative to human rescue workers may be robotic cockroaches. real cockroaches are protected by strong yet flexible exoskeletons. they can also flatten their bodies through tiny cracks. a robotics researcher from harvard university and a biomechanics expert from the university of california, berkeley, were inspired to create mini robots that have the same features. the roach robots can squeeze through small spaces and skitter over unstable environments. fitted with cameras and microphones, they could be used in disasters to locate victims.\nwhat is the main, or central, idea of the passage?\ncockroach - like robots can fit through small cracks and move through unstable rubble.\ninspired by the strength and quickness of cockroaches, researchers created robots with the same characteristics.\nit is dangerous to search inside collapsed buildings, but cockroach - like robots can go places where human searchers cant or shouldnt.

Answer

Brief Explanations:

The passage first mentions the danger of rescuing in collapsed - building scenarios for human workers. Then it explains that researchers were inspired by cockroaches to create robots with similar features that can access places humans can't safely reach for rescue purposes.

Answer:

It is dangerous to search inside collapsed buildings, but cockroach - like robots can go places where human searchers can't or shouldn't.
