Problems solved by technology

At present, fruit picking is mainly manual picking, but the cost of manual picking is high and the efficiency is low. The picking process often requires tools such as ladders, which is dangerous
There are also some picking robots on the market, but many fruit trees are planted in mountainous areas, and most of the picking robots walk on land, which is difficult to apply to picking fruit trees in rugged mountainous areas
[0003] At present, picking robots have problems such as small body, small load, low efficiency, and poor environmental adaptability. The design of picking robots often focuses on the structure of picking, and relatively little attention is paid to whether it can adapt to the picking environment and whether the power can meet the standards. Moreover, in terms of picking accuracy, the impact of the environment on picking accuracy cannot be underestimated, but there are few studies on this effect in the prior art

Embodiment 1

[0073] A four-degree-of-freedom multi-eye vision flying picking robot, such as figure 1 As shown, it includes unmanned aerial vehicle 1, picking mechanism 2 and multi-eye vision device 4; said picking mechanism 2 and multi-eye vision device 4 are installed on the unmanned aerial vehicle 1; Machine 3 and computer 5 are connected together for data transmission and system control.

[0074] Described picking mechanism 2 comprises telescoping rod 21, picking manipulator 22, as figure 2 shown. The telescopic rod 21 has at least three sections, including the first section 211, the middle section 212 and the last section 213, wherein the middle section is more than one section, and the first section, the middle section and the last section are nested in a stepped manner; The front end of the first pole is installed in the body of the drone, and the end of the last pole is equipped with a picking manipulator. Except that the last pole is not telescopic, other poles can be telescopi...

Embodiment 2

[0081] Such as Figure 6 As shown, the rotary flying picking robot based on four-degree-of-freedom multi-eye vision, in the picking process, firstly, the UAV 1 is on land, records the initial position, obtains the harvesting position Z through measurement, and obtains the fruit image through the positioning camera 42 , carry out position initialization; Open the telescoping link 21 of picking hand again, all stretch, open servomotor, rotate last joint bar 213, drive picking manipulator 22, make picking manipulator three fingers be inverted triangle shape (such as Figure 10 shown in the picking state), and through the wire, the joint ring 215 is de-energized, so that the spring 216 squeezes the sliding guide 217, and then resists the long rod 225, and the middle knuckle 222 turns outward. At this time, through the inside of the long rod The wire is used to control the entire extension of the middle phalanx, and the last phalanx 223 is everted to complete the picking and stretc...

Embodiment 3

[0083] Such as Figure 7 As shown in Figure b, the lower fruit is picked. When the upper fruit is to be picked again, it is not necessary to repeat the positioning. It is directly at the original position, the rear rotor speed is reduced, the front rotor speed is increased, the middle rotor speed remains unchanged, and the UAV pose After the change occurs, the backward movement is completed, the telescopic rod is extended, and the upper fruit can be reached, which is the pose in figure a. Main picking operation in this process is all identical with embodiment 2.

Abstract

The invention discloses a four-degree-of-freedom multi-eye visual rotary flight type picking robot and a picking method thereof. The picking robot comprises an unmanned aerial vehicle, a picking mechanism and a multi-eye visual device, wherein the picking mechanism comprises a telescopic rod and a picking mechanical hand, and the picking mechanism and the multi-eye visual device are mounted on theunmanned aerial vehicle; and the unmanned aerial vehicle communicates with an industrial control computer and a computer through a cable or wireless manner for data transmission and system control. Integrated design of the unmanned aerial vehicle and the picking mechanism is realized, the four-degree-of-freedom multi-eye visual rotary flight type picking robot is a four-degree-of-freedom pickingrobot, multiple-oriented picking can be realized, the picking range is extended, and the picking efficiency is improved; and the designed picking mechanical hand can dynamically change free expandingand contracting of middle finger joints of three fingers according to the size of fruits, the holding capacity of the mechanical hand on the fruits is improved, and the applicability is high.

Description

technical field [0001] The invention relates to the field of picking machinery, in particular to a four-degree-of-freedom multi-eye vision spinning flying picking robot and a picking method thereof. Background technique [0002] my country is a big country in fruit production and planting, and fruit picking is an important link. At present, fruit picking is mainly manual picking, but the cost of manual picking is high and the efficiency is low. The picking process often requires tools such as ladders, which has certain risks. There are also some picking robots on the market, but many fruit trees are planted in mountainous areas, and most of the picking robots walk on land, which is difficult to be suitable for picking fruit trees in rugged mountainous areas. [0003] At present, picking robots have problems such as small body, small load, low efficiency, and poor environmental adaptability. The design of picking robots often focuses on the structure of picking, and relative...
