AI Technical Summary

Technical Problem

Existing spindle-type cotton harvesters cause cotton fibers to break, thin, and become tangled during long-staple cotton harvesting. In addition, manual harvesting is slow, labor-intensive, and inefficient, resulting in reduced quality of long-staple cotton and high harvesting costs.

Method used

Design a vision-based multi-arm cotton picking robot, including a chassis, robotic arms, and a cotton collection box. The chassis is divided into three layers. The robotic arms have cotton conveying channels inside and are equipped with four robotic arms. The robot uses LiDAR navigation and cameras to identify the position of the cotton, and performs precise picking through the robotic arms. It also uses a fan to generate negative pressure for picking and conveying.

Benefits of technology

It enables precise positioning and harvesting of cotton fibers, reduces fiber damage, improves harvesting efficiency and cotton cleanliness, and reduces labor intensity and harvesting costs.

Abstract

The application discloses a kind of multi-arm cotton picking robot based on vision, it is related to cotton picking machine technical field, including chassis, cotton picking device, mechanical arm and cotton collecting box, the chassis is divided into three layers, the first layer is the growth area of cotton plant to be picked, the cotton picking device and four mechanical arms are fixedly connected with the second layer of chassis, and the inside of the mechanical arm is provided with the passage that can supply cotton conveying, the cotton collecting box is fixedly connected with the third layer of chassis;The end of the mechanical arm is moved to the vicinity of the cotton to be picked in the application, under the action of the suction of cotton picking device, cotton is brought into cotton collecting box;The application overcomes the phenomenon that cotton linter fiber is pulled off, pulled thin, causes around knot, etc., caused by traditional picking spindle type cotton picker, by pneumatic picking and conveying, the quality of long lint cotton is greatly improved, and the problem of slow artificial harvesting speed and high labor intensity is also solved.
