For farmers, collecting cotton, growing vegetables, spraying drugs and grafting crops are all laborious tasks. How to let farmers get rid of heavy agricultural operations without delaying farming has become a problem for many R&D personnel. The birth of "agricultural robots" solved many of the peasants' worries.
"Robot" comes to the field of farming operations intelligent
Robot that will receive cotton
Wang Ling, an associate professor at the College of Engineering at Nanjing Agricultural University, has developed a robot that not only picks cotton, but also quickly and accurately determines the grade of seed cotton.
For farmers, collecting cotton is a chore. Moreover, the cost of artificial cotton picking is quite large, and the labor input is about 50% of the entire production process. For example, in the Xinjiang Production and Construction Corps, 7 million mu of cotton is planted, and the annual picking fee is nearly 400 million yuan.
The robot developed by Wang Ling and the team knew before the picking which piece of cotton had good quality and which piece of cotton had poor quality, thus avoiding duplication or unnecessary labor. In planting, the planting distance of the cotton plants only needs to satisfy the width of the robot, and the cotton field is given a certain width to satisfy the working width of the picking robot.

a robot that will grow vegetables
At the “Shouguang Vegetable Expoâ€, intelligent robots independently developed by Shouguang Science and Technology personnel shuttled through the vegetable racks, and the picking and management actions were precise and smooth, allowing visitors to experience the convenience and efficiency brought by intelligent planting in zero-distance contact.
It is understood that the energy systems of these kinds of robots use solar panels to convert solar energy into electrical energy, and store the electrical energy through a battery for variable voltage frequency conversion. When the robot is low in power, it automatically searches for the charging location and automatically completes the charging docking. When the robot is fully charged, continue with the last unfinished task.
a robot that sprays drugs
This is a giant of three or four people. Its green shell shape is similar to the "alien" in science fiction film and television works. It is actually a spray machine produced by a plant protection company in Beijing in cooperation with Italy and Spain.
It is understood that when a cornworm disease disaster occurs, farmers probably hire people to fight drugs at a price of 150 yuan per day per person, and still cannot hire enough people. When the corn matures, the height of the straw is generally close to two meters. The ordinary hanging sprayer sprayer does not go to the ground, and the farmers can only watch the rush. This "external robot" can adjust the line spacing and height freely, and its unique design can easily enter the fields of various high crops without causing damage to crops.

Grafting robot
The grafting robot was successfully developed by Professor Zhang Tiezhong, the head of the Agricultural Robot Laboratory of the College of Engineering, China Agricultural University. The robot is divided into the seedling system, the rootstock seedling system, the cutting and bonding, and the fixed part.
Zhang Tiezhong's demonstration of cucumber seedlings and pumpkin seedlings were placed in the seedlings and rootstocks for seedlings. In one step, the machine completed the multi-step operations such as precise positioning, grasping and cutting, and joint fixation. From the release of the seedling to the successful grafting, the whole process is only a few seconds.
This universal vegetable grafting robot has completed at least 400 plants in one hour. Another more advanced two-way high-speed vegetable grafting robot in the laboratory can complete 800 plants in one hour, which is 6 to 7 times that of manual work. At the same time, the survival rate of robot grafted seedlings is as high as 95%.
Robot sorting fruit
In agricultural production, the sorting of various fruits is an essential farm work, often requiring a large investment in labor.
Researchers at a farm machinery research institute in the UK have developed a robust, easy-to-use fruit sorting robot that automates fruit sorting.
It uses an electro-optical image discrimination and lifting sorting machine combination to work in wet and muddy environments. It distinguishes large tomatoes and small cherries, sorts and ships, and classifies potatoes of different sizes. And will not scratch the skin of the fruit.
