Flapping-wing flight,as the distinctive flight method retained by natural flying creatures,contains profound aerody-namic principles and brings great inspirations and encourage-ments to drone developers.Though some ingenious flapping-wing robots have been designed during the past two decades,develop-ment and application of autonomous flapping-wing robots are less successful and still require further research.Here,we report the development of a servo-driven bird-like flapping-wing robot named USTBird-I and its application in autonomous airdrop.Inspired by birds,a camber structure and a dihedral angle adjustment mechanism are introduced into the airfoil design and motion control of the wings,respectively.Computational fluid dynamics simulations and actual flight tests show that this bionic design can significantly improve the gliding performance of the robot,which is beneficial to the execution of the airdrop mission.Finally,a vision-based airdrop experiment has been succcessfully implemented on USTBird-I,which is the first demonstration of a bird-like flapping-wing robot conducting an outdoor airdrop mis-sion.
