Nanjing Nongda Develops Cotton Picking Robot

Recently, the team of Wang Ling, an associate professor of Engineering School of Nanjing Agricultural University, has developed a kind of

For farmers, picking cotton is a tough job.

Wang Ling introduced that the labour force invested by artificial cotton accounts for about 50% of the whole production process.

For example, in the Xinjiang Construction Corps, 7 million mu of cotton is planted and flowers are collected every year.

According to the introduction, the researchers first used the CCD digital camera to collect the front image of the three cotton seed cotton 12 to 1, 7 grades in the early, middle and late stages. The total image of the cotton seed was 350. After that, the seed cotton image was segmented from the complex background by technical treatment. The 14 texture characteristics reflecting the cotton whiteness, yellow and impurity content and 16 shape characteristics reflecting the size and structure of the cotton seed were used to classify and classify the seed cotton, and the recognition rates reached 85.3% and 88.4% respectively.

When picking cotton picking robot, binocular vision camera and image acquisition card are used to collect cotton images, and image processing is done to locate cotton coordinates.

After approaching the plant, the robot picks up through the rotation of the manipulator arm.
