Scientists have created a drone with bat wings: why it is better than conventional models (video)
A group of American scientists has created a unique robot-drone called Aerobat, capable of changing its shape in flight and penetrating narrow spaces inaccessible to traditional drones. This flexible-wing drone is inspired by the anatomy of bats. The new development was reported by the Popular Science publication, referring to research, published в International Journal of Robotics Research.
Known for their ability to maneuver, bats can dynamically change the shape of their wings for maximum efficiency and flexibility. Their wings consist of a soft membrane, similar in structure to a human hand, which allows them to bend and fly through very narrow passages. These features were taken as a basis when creating the Aerobat to ensure the ability to move in difficult conditions, such as sewer tunnels, caves or other confined spaces.
A team of scientists from Northeastern University used a combination of soft and hard materials created with a 3D printer to recreate the structure of a bat’s wings. Such wings can expand when moving down and contract when climbing, creating powerful air jets that provide high aerodynamic efficiency.
“In some literary sources, the flight of bats is described as a dance in the air. They don’t just fly, they dance in the air with great composure. They try to manipulate their current environment, and this is unique to a batin,” explained Alireza Ramezani, associate professor at Northeastern University and lead author of the study.
Aerobat is equipped with a camera for orientation in space and a computer system for autonomous flight control. A person only sets the final destination, and the drone independently covers the route using its wings. The drone can also hover in place, gathering information about the environment using built-in sensors.
Aerobat developers emphasize that this drone is an ideal solution for tasks in closed and limited spaces where traditional drones cannot work effectively.
