DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] With the continuous development of drone technology, their application in logistics and distribution, precision agriculture, environmental monitoring, and other fields has gradually increased. In particular, drones have become an ideal choice for precise object delivery tasks due to their high efficiency and flexibility. However, existing drone delivery systems face challenges in delivery accuracy, control stability, and object sequence. In particular, when delivering multiple objects sequentially and precisely guiding them, traditional mechanical structures and control systems often struggle to meet the requirements for high precision and efficiency.

[0034] Related art discloses a precision delivery device capable of sequentially delivering multiple materials and equipped with a flexible guide mechanism. The device comprises a delivery mechanism for carrying and sequentially delivering multiple materials; a flexible guide mechanism at the end of the delivery mechanism effectively guides the materials to their target location. Both the delivery mechanism and the guide mechanism are precisely controlled by a stepper motor, ensuring stability and high precision during the delivery process. This precise control by the stepper motor enables real-time adjustment and precise positioning of material delivery, meeting the requirements of a variety of complex tasks. This device has significant application potential and broad development prospects for drones in fields such as precision delivery, logistics distribution, and environmental monitoring. The flexible guide mechanism primarily utilizes flexible materials to precisely guide materials. The highly elastic flexible guide material effectively slows the material's velocity during its descent, thereby reducing the impact force that may occur when the material contacts the ground. This design significantly improves material delivery accuracy and reduces the risk of damage, making it particularly suitable for missions requiring high-precision delivery. The flexible guide material is not only elastic but also lightweight and compact, minimizing the overall weight of the delivery system without significantly increasing the drone's payload. Its compact design also effectively optimizes the spatial layout of the system, improves the flight efficiency and maneuverability of the drone, and thus ensures the system's good performance in various complex environments.

[0035] The above-mentioned related technologies can only realize vertical fixed-point delivery of materials, and cannot guarantee stability during the delivery process. At the same time, the delivery mode is single and cannot meet different usage requirements. In order to solve the above problems, this application provides the following technical solutions:
