Sensors for bat-inspired spy plane under development
The U.S. Army has awarded the University of Michigan College of Engineering a five-year, $10-million grant to help develop a six-inch robotic spy plane modeled after a bat.
Low-power miniaturized radar and a very sensitive navigation system would help the bat find its way at night. Energy scavenging from solar, wind, vibration and other sources would recharge the bat's lithium battery. The aircraft would use radio to send signals back to troops.
