(PBS NewsHour) With bees in decline, some see a business opportunity. A company called Dropcopter is trying to create a drone to spread pollen. Harvard University’s Wyss Institute is designing a miniature autonomous flying vehicle they call the Robobee that might be used for pollination. But some bee experts are skeptical of a technological fix and say we need to focus more on protecting the real live bees that are still here.
(New York Times) For years, scientists have sought to build aerial robots inspired by bees and other flying insects. But they have always run into a fundamental problem: Flying takes a lot of energy. “Having onboard power is the first big step to getting microrobots out of the lab and into the real world.”
(Montana State University) Unmanned aircraft are growing ever more popular — and smaller. But spinning rotor blades can be downsized only so much before air friction overtakes lift force, causing the tiny motors to overheat and fail. Flapping wings, on the other hand, can scale down almost indefinitely.
(MIT News) “We currently have no robotic alternative to bees for pollination of many crops. If we want to grow crops on Mars, we may need to bring bees with us. Knowing if they can survive a mission, reintegrate into the hive, and thrive afterwards is critical.”
