Problems solved by technology

[0005] 2. The picking efficiency is not high
[0006] 3. The fruit collection effect is not good
[0007] 4. Higher cost
The fruit and vegetable picking robot system and structure are more complicated, and the service cycle is short, so it is basically not used
Maintenance, use, and manufacturing costs are all higher than industrial robots
[0008] 5. Poor versatility
A picking robot only completes a single task for a specific plant, and there is little commonality among various types of robots

Embodiment 1

[0049] The robot of picking day lily of the present invention, as figure 1 As shown, it includes a trolley 1; one end of the trolley 1 is provided with a power supply and a power control device 2 , the other end is provided with a laser navigation system 13 , and a mechanical arm is provided on the top of the trolley 1 . The mechanical arm includes a base 6, a shoulder joint 7, an elbow joint 8, and a wrist joint 10 connected in sequence. The base 6 is provided with a motor, the shoulder joint 7 is provided with a motor, the elbow joint 8 is provided with a motor, and the wrist joint 10 is provided with a motor. The upper end of the base 6 is connected to the shoulder joint 7, the upper end of the shoulder joint 7 is connected to the elbow joint 8, the upper end of the elbow joint 8 is connected to the wrist joint 10, and the wrist joint 10 is connected to the binocular camera 11 and the mechanical finger 9 through the adapter device 18, The binocular camera 11 is composed of ...

Embodiment 2

[0057] The method for picking day lily comprises the steps:

[0058] a. Start: the daylily picking robot starts, and the car 1 walks from the collection place to the picking area according to the navigation walking system;

[0059]b. Recognition and positioning: the binocular camera 11 is based on the principle of binocular stereo vision positioning, through image acquisition, comparison with samples in the image database, extraction of target feature points, camera calibration, image processing, stereo matching and three-dimensional reconstruction; Obtain the parallax between the matching points of the image pair, obtain the three-dimensional coordinates of the feature points, and feed them back to the power supply and power control device 2;

[0060] c. Picking: The host computer sends instructions to the controller through the CAN bus to control the movement of the shoulder joint 7, elbow joint 8, wrist joint 10 and adapter device 18 in the robotic arm, and the motor that d...

Abstract

The invention discloses a robot and a method for picking daylily. According to the invention, a navigation walking system is adopted for navigation and positioning of the robot; a fruit picking systemis adopted for mechanical picking of the daylily; an object identification and positioning system is adopted for accurate identification and positioning in picking operation; a fruit collection device is adopted for timely collection of picked daylily; and an electric source and power control device is adopted for intelligent control to all systems. Through mechanical and electrical combination,and by combination of the growth characteristics and picking requirements of the daylily for highly-efficient picking, the manner of replacing manual labor with the robot is realized. The method provided by the invention controls the picking path of the robot for picking the daylily; three-dimensional coordinates of a feature point are obtained to be fed back to the electric source and power control device, so the feasibility and accuracy of the whole picking operation are guaranteed; and picking operation of the daylily is completed, and the picked daylily is timely collected, so the pickingand collection efficiency of the daylily is improved, the number of times of handling can be effectively reduced, and the quality of picked daylily is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to a robot and a method for picking daylily. Background technique [0002] Day lily has good quality, delicious taste, high nutrition, large planting scale and high yield. It occupies an important position in the agricultural industrial structure. It is one of the main economic incomes of farmers and a hope industry for farmers to get rich. And with the discovery that day lily has the effect of preventing senile dementia, the number of middle-aged and elderly people who eat it will increase, so the planting scale of day lily will become larger and larger in the future. However, due to the fact that day lily picking is completely manual, the labor intensity is high and the efficiency is low. As the rural labor force gradually transfers to the secondary and tertiary industries and cities and towns, the rural labor force will become more and more scarce, and the planting ...
