A lifting and landing platform for agricultural drones based on serial elastic drives

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 agricultural drone control, in particular to an agricultural drone landing platform based on a series elastic driver. Background technique [0002] Unmanned aerial vehicle is a kind of aircraft that does not need to be operated by a pilot, is controlled by radio remote control or its own program, uses aerodynamics to carry the flight, and can be used repeatedly. It has low operating altitude, small drift, hovering in the air, and long distance. It has advantages such as remote control, no need for a dedicated take-off and landing airport, and 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. Depending on the task, the take-off and landing positions of agricultural drones and the agri...

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.
