Problems solved by technology

[0004] The receiving platform used in the existing drone recycling scheme is a fixed platform or a mobile platform with large limitations. When the drone lands, it is easy to collide with the receiving platform due to its high speed, high inertia and lack of buffer devices.
In addition, this solution is easily affected by factors such as harsh environment, carrier movement, UAV's own performance, and airflow in the take-off and landing area. The phenomenon of "one foot touching the ground" is prone to occur when the UAV lands, causing the UAV to occur sideways. Turnover and fuselage damage

Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] The invention provides an autonomous recovery system for unmanned aerial vehicles based on the Stewart receiving platform, including a data acquisition module, a posture following module, a flexible receiving module, a stable vibration isolation module and a comprehensive processing module; , high real-time, and high robustness motion control to realize autonomous and flexible take-off and landing of UAVs; its overall system is as follows: figure 1 .

[0027] The data acquisition module collects the pose information of the drone; recognizes and tracks the pose of the drone in real time. Guide the "independent drive and independent steering" smart car to load the lifting platform and move to the vicinity of the drone's operating position.

[0028] When the UAV receives the request to land, keep the attitude of the receiving platform consistent with...
