Agricultural unmanned aerial vehicle takeoff and landing platform based on elastic series drivers

Abstract

The invention discloses an agricultural unmanned aerial vehicle takeoff and landing platform based on elastic series drivers. The unmanned aerial vehicle takeoff and landing platform adopts the elastic series drivers to replace traditional movement pairs, utilizes their elastic deformation to achieve transfer and conversion of movements and energy, flexible buffer in the descending process of agricultural unmanned aerial vehicles can be achieved, meanwhile the bounciness of the elastic drivers during descending of unmanned aerial vehicles can be also balanced, and vibration force is greatly weakened.

Description

technical field [0001] The invention relates to the field of control of agricultural unmanned aerial vehicles, in particular to an agricultural unmanned aerial vehicle landing platform based on a serial elastic drive. Background technique [0002] UAV is a kind of reusable aircraft that does not need to be operated by a driver, is controlled by radio remote control or its own program, and uses aerodynamics to fly. It has low operating height, small drift, hovering in the air, and remote With the advantages of distance remote control and no need for special landing airports, it can be widely used in agricultural operations such as pest control, fertilization, pesticide application, weed identification and yield estimation of wheat, rice, cotton and other crops. [0003] Agricultural drones usually need to carry a certain weight of load when performing flight tasks. According to different tasks, the location of take-off and landing of agricultural drones and the agricultural e...

AI Technical Summary

Problems solved by technology

[0003] Agricultural drones usually need to carry a certain weight of load when performing flight tasks. According to different tasks, the location of take-off and landing of agricultural drones and the agricultural environment are not fixed, and they are easily affected by external factors such as terrain, wind speed, and operating conditions. Influenced by human factors such as improper operation by the operator, the agricultural drone cannot achieve a smooth landing when it lands. When it is subjected to excessive shock force, it may cause damage to the agricultural drone body and mounted load.
