World's smallest flying robot

Post date: May 2, 2013 8:52:10 PM

Scientists in the US have created a robot the size of a fly that is able to perform the agile manoeuvres of the ubiquitous insects. This "robo-fly", built from carbon fibre, weighs a fraction of a gram, less than a tenth as much as a paper clip, and has super-fast electronic "muscles" to power its wings. It can hover almost motionless in the air or perform sudden evasive manoeuvres. And just like a real fly, the robot's thin, flexible wings beat approximately 120 times every second.Its Harvard University developers say tiny robots like theirs may eventually be used in rescue operations. It could, for example, navigate through tiny spaces in collapsed buildings.
