With　the　rapid　advancements　in　unmanned　aerial　vehicle　(UAV)　technology,　new　solutions　have　emerged　to　address　logistics　challenges　in　certain　areas.　Drone　deliveries　can　reach　locations　that　are　inaccessible　to　traditional　logistics　methods.　However,　existing　cargo　drones　face　difficulties　with　takeoff　and　landing　on　complex　terrains　due　to　their　fixed　landing　gear.　This　paper　introduces　the　design　of　a　bionic　specialized　quadrupedal　UAV,　capable　of　moving　and　climbing　on　complex　terrains,　aimed　at　improving　UAV　cargo　operations　in　challenging　environments.
