Harvard Researchers have created the world’s smallest drone. Named the RoboBee, the penny sized drones fly by flapping their two dual membrane wings 120 times a minute. While most drones are used for spying or military purposes the RoboBee’s engineers have hopes that their 'bot can be used for search and rescue, crop pollination and environmental monitoring.
