"The shepherd boy riding a yellow ox" is a rural farming scene depicted in many literary works, but now it is different from the past. Recently, reporters saw at Diantian Farm in Tinglin Town, a suburb of Shanghai, agricultural robots and engineers who had finished their work "walking" on the field ridges one after another. "Iron cows" replaced yellow cattle, and engineers replaced cattle herders. Engineer Li Wei, born in the 2000s, always walks on the field with his robot in front of him, holding a remote control. From a distance, it feels like he is grazing an "iron ox". There are still over 70 engineers like Li Wei in the Diantian Cooperative. For over seven years, they have been working hard here, developing over 60 agricultural robots that cover every step from sowing to harvesting. These "iron oxen" all have tracked "feet" that can adapt to various terrains. In addition, they also possess a "smart brain" from the company's independently developed AI intelligent operating system, which uses algorithms to write a set of "motion logic" for robots. Farmers log in to the system on their mobile WeChat mini program and an interactive interface appears. By adjusting the direction, the robot can automatically start working. Wang Jinyue, Chairman of Shanghai Diantian Agricultural Professional Cooperative, said, "At first, I started working on agricultural machinery and equipment because of a farming experience many years ago. I grew up in a rural area, and although I am tall and strong, I feel very tired working all afternoon. I left my hoe and thought about whether I could get some mechanical equipment to farm, and then slowly entered this industry." "The advantages of agricultural robots are: fast, accurate, and tireless." Wang Jinyue said, Through 5G, image recognition technology, and big data systems, harvesting robots can 'instantly' calculate the distance between crop fruits and the human body of the machine, and transmit relevant instructions to the robot arm to achieve rapid harvesting. Weeding robots can not only accurately distinguish between grass and crops, but also command weeding tools to accurately remove weeds, just like growing eyes. A weeding robot can work for 8 hours after charging for 1 hour, and large machines can work for 8 hours A person can weed around 500 acres per day Stepping into the sweet spot farm, on the road in the middle of the park, you can see the evolution of generations of "sweet spot robots" over the years, including rotary tillage robots, seeding robots, and plant protection robots... From simple splicing to now software and hardware compatibility, a long column is packed and stopped, like an agricultural machinery museum placed in the field. The scenes are different, but the intelligence is the same. A team of high-tech new farmers is also active in Hanzhong, Shaanxi, thousands of miles away. They use intelligent devices to lower the cost and increase efficiency of vegetable cultivation. Entering the automated vegetable factory, the land inside the intelligent greenhouse is divided into several equal parts. After the automatic rotary tiller tilts and flattens the land, the automatic seeder will lay boards with holes drilled according to different plant spacing on the ground, and then accurately sow the seeds into the holes of the planting boards. "One hole can grow one seed, and one machine can grow two acres of land per day," said Guo Qiang, General Manager of Shaanxi Rili Photosynthetic Biotechnology Co., Ltd. "Remote control, remote monitoring, realizing unmanned production, automated operation, and factory management throughout the entire process of green leaf vegetable cultivation. Only 5 workers are needed for a 200 acre vegetable park." Guo Qiang
