'RoboBees' to help build better drones
Inspired by nature, scientists have developed a new type of flying microrobots called “RoboBees” which can perch during flight like bats, birds or butterflies to save energy and stay in the air for long durations and help develop future drones.
“Many applications for small drones require them to stay in the air for extended periods,” said Moritz Graule, lead author from Harvard University.
Unfortunately, smaller drones run out of energy quickly.
“We want to keep them aloft longer without requiring too much additional energy,” he added.
