Inspired by bees and other flying insects, scientists have developed insect-sized robots that can flap their wings to fly, according to a report by Sky News. This new technique could lead to smaller, lighter and more effective micro flying robots, which could be used for environmental measuring, search and rescue, and in dangerous surroundings such as collapsed buildings.
Known as micro air vehicles, the robots are better than other drones at maneuvering in tight spaces and resisting air turbulence. The technology means conventional motors and gears are no longer needed to fly the devices. Until now, similar machines have used motors, gears and other complicated systems to achieve the up-and-down motion of the wings, which added complexity, weight and other unwanted effects.
