Cyborg Roaches
You might not
think of roaches as the hero type.
But researchers at North Carolina State University are hoping they will be.
They call them bio-bots . Scientists have strapped tiny backpacks onto cockroaches that manipulate their neural systems
so they can steer them into small, dark spaces or guide them through a maze .

The backpacks contain tracking gear and tiny microphones that pick
up sounds of trapped victims` cries for help, alerting
rescuers to their locations .
Theoretically, rescuers could control the roaches by using apps on their smart phones.

What`s next? Eventually , the bio-bots could be mounted
with tiny cameras ,
or infrared sensors that can detect heat , another way to find people trapped under debris.
If this technology proves successful, first responders may someday arrive on the scene
with a box of cockroaches wearing backpacks.
