Problems solved by technology

[0003] Although the "counterweight" adjustment method can alleviate the problem of unbalanced center of gravity of the UAV, it increases the load of the UAV, increases the power consumption of the electric UAV, and affects the endurance time and flight safety of the UAV.
At the same time, when the UAV is operating, the weight of the load will gradually change (increase or decrease) as the operation progresses, and then continuously change the position of the center of gravity of the UAV, thus affecting the weight of the UAV during flight. balance
[0004] At present, there are few social applications for fruit picking by drones. Most of the existing fruit picking by drones is to collect small fruits. Human-picked
The balance of the drone itself cannot cope with the sudden increase in the weight of the front end after fruit picking

Embodiment 1

[0039] Such as Figure 1-Figure 3 As shown, the present embodiment is a kind of unmanned aerial vehicle self-balancing picking device based on the lever principle, including electric fruit picking device 1, camera fixing bracket 2, binocular vision camera assembly 3, front rod main body 4, connecting mechanism 5, ball screw Slide table 6, rear rod main body 7, weight box 8, scissors mechanism 9, weight sensor 10 and fruit branch clamping mechanism 11; Ball screw slide table 6 is set between described front rod main body 4 and rear rod main body 7, so One end of the ball screw slide table 6 is fixed on the front rod main body 4, and the other end is connected to the front end of the rear rod main body 7. When the ball screw slide table 6 moves, it drives the rear rod main body 7 to move telescopically.

[0040] Further, such as Figure 7As shown, the front end of the front rod main body 4 is provided with an electric fruit picking device 1, and the electric fruit picking devic...

Embodiment 2

[0050] The present invention also provides a control method of a self-balancing picking device for unmanned aerial vehicles based on the principle of leverage, comprising the following steps:

[0051] (1) After installing the UAV fruit picking device, adjust the balance of the UAV. If the self-equipment cannot achieve balance, you can use the corresponding counterweight to place it in the counterweight box to make the UAV overall balanced.

[0052] After adjusting the balance, start the UAV, the UAV takes off, first conduct the inspection of the UAV equipment, and then carry out the fruit picking operation after the inspection is completed.

[0053] Position the fruit through the binocular vision camera, and the UAV controls the UAV to fly to the designated position through the flight control system. After arriving at the designated position, the UAV continuously scans the fruit through the binocular vision camera to adjust The position of the machine is such that the mother b...

Abstract

The invention discloses an unmanned aerial vehicle self-balancing picking device based on the principle of leverage and a control method thereof. Platform, rear pole main body, counterweight box, scissors mechanism, weight sensor and fruit branch clamping mechanism; when in use, first fix the device on the drone, search for the target through the image collected by the binocular vision camera and fine-tune the position of the drone , and then through the central control to control the electric fruit picking device to perform the picking operation and the work of the ball screw sliding table. The calculation results are used to adjust the telescopic length to basically balance the sudden increase in the weight of the sudden increase in the front-end load mutation fruit picked by the UAV, so as to ensure the stability of the UAV. The invention is suitable for use in the fields of fruit harvesting and pruning in forest orchards.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, in particular to an unmanned aerial vehicle self-balancing picking device based on the principle of leverage and a control method thereof. Background technique [0002] When the drone is unloaded, its center of gravity is placed on the central axis of the fuselage, so as to achieve the balance of the drone during flight. However, due to the different application fields of drones, the weight of the equipment carried by them will vary greatly. For example, installing a digital camera, professional video camera, medicine box, medicine powder container, etc. on the nose position will affect the center of gravity of the drone, thereby affecting the balance of the drone during flight. In order to improve the balance of the UAV, the method of setting "counterweight" is usually used at present, that is, when the nose is equipped with some equipment, by loading a certain weight object o...
