At present, countries with relatively developed agriculture in the world have mainly developed the following types of agricultural robots

speaking of modern agriculture, if you still have the impression that it is only a large mechanized farm in the United States, or a small farmland with fine management in Japan, South Korea and other countries, or an intelligent plant factory in Israel, it is really out. In fact, even people who are full-time engaged in agriculture, such as writers, are not aware of the new trend in the agricultural field, That is artificial intelligence. Specifically, in today's farmland or greenhouse, in addition to people and mechanical equipment, many agricultural robots have begun to appear

with the rapid development of artificial intelligence in recent years, the combination of artificial intelligence and all walks of life has entered the stage of substantive application. For example, in the field of agriculture, the development of smart agriculture is in full swing. The so-called smart agriculture is a combination of emerging Internet, mobile Internet, cloud computing and IOT technology, Relying on various sensor nodes (environmental temperature and humidity, soil moisture, carbon dioxide, images, etc.) and wireless communication networks deployed in the agricultural production site, we can realize the intelligent sensing, intelligent early warning, intelligent decision-making, intelligent analysis and expert guidance of the agricultural production environment, and provide precision 175 steel plate stamping fasteners with standardized planting, visual management and intelligent decision-making for agricultural production. Relying on the development of intelligent agriculture, agricultural robots use GPS navigation technology, sensor technology and the latest robot technology to achieve accurate positioning and identification of agriculture, and replace human beings to complete agricultural sowing, fertilization, irrigation, picking, transportation and other manual labor, so as to further save a wide range of human costs and improve agricultural production efficiency

since the birth of mankind, it has experienced the development stages of primitive collecting agriculture, traditional agriculture, chemical agriculture, mechanical agriculture, factory agriculture, intelligent agriculture and so on. Every progress in agriculture is accompanied by a substantial increase in labor productivity. It is the improvement of agricultural production efficiency that has fed an increasingly large population in the world. However, with the aging trend of the world population becoming more and more serious, global agriculture is facing a huge labor shortage. According to the world bank, by 2050, 50% more food will be needed to maintain the recent growth of the global population. On average, each agricultural labor force should be able to produce food for 500 people. The rising cost of global agricultural labor has provided sufficient impetus for the development of agricultural robots. Through automation and robot technology, we can improve the output and work efficiency of agricultural production, alleviate the problem of labor shortage, and reduce the damage of pesticides to the soil, water and other natural environment

at present, countries with relatively developed agriculture in the world have mainly developed the following types of agricultural robots

1. weeding robot

this robot is from ecorobotix company in Switzerland. Its main product is the field weeding robot. Through machine recognition technology, weeds can be accurately identified. Many enterprises have not been able to skillfully use its mechanical arm to spray herbicides on weeds after purchasing the impact experimental machine, which has reduced the use of herbicides by 20 times compared with the traditional method. The robot fully realizes automatic operation without any operator. Driven by solar energy, it can work for up to 12 hours a day. At the same time, the robot weighs only 130 kg, which is far lighter than traditional agricultural machinery and equipment, minimizing the damage of machinery to the soil

2. fertilization robot

an agricultural machinery company in Minnesota has developed a unique fertilization robot, which can formulate different fertilization strategies according to the actual situation of different types of soil. Adopting this precise fertilization technology can greatly reduce the amount of fertilization, not only save agricultural costs, but also reduce the pollution of fertilizer to the farmland ecological environment

3. pesticide spraying robot

this crop pesticide spraying robot developed by maggrow, an Irish pesticide spraying technology company, is committed to solving the problem of drug drift in the process of pesticide spraying. Using permanent rare earth magnets to generate electromagnetic charges and magnetize pesticide droplets to make it easier to observe that the oil surface of the hydraulic control box is attached to the crops, which can achieve an adhesion rate of 85-95%, reduce the use of pesticides by 65-75%, and increase the crop yield by 20-40%

4. Pollination robot

this bee robot developed by an American company can replace bees to complete plant pollination. In addition, due to its strong endurance and small size, this robot can be applied to post disaster investigation, search and rescue and other work

5. grazing robot

an Australian company has invented a grazing robot, which can replace the traditional grazing labor on the farm. It uses 2D and 3D sensors, and has a built-in global positioning system, which can automatically detect the movement speed of cattle and drive them away

6. picking robot

finally, this cucumber picking robot independently developed by China Agricultural University is recommended. This robot uses the multi-sensor fusion function to obtain information, judge the maturity of picking objects, and determine the spatial position of picking objects. It can realize autonomous navigation movement in unstructured environment, rapid search of regional vision, recognition of fruit maturity characteristics in local vision And fruit spatial positioning, end effector control and operation, and finally realize the picking and harvesting of cucumber fruits

the above six types of robots are only a small part of the people's family of agricultural robots. The biggest advantage of agricultural robots over humans is that they can work 24 hours a day without interruption, and basically there will be no operational errors. The disadvantage is that the first purchase cost is still relatively high, and regular maintenance is required

in the long run, although agricultural robots represent a new stage of agricultural development, they are not the ultimate form of agricultural development. Because both traditional agriculture and intelligent agriculture are the process of using the growth characteristics of crops to produce food for human beings under the conditions of sufficient soil, water, light and other conditions. In the stage of industrialized agriculture, although the growth conditions of water, light and nutrition required by crops can be controlled to a certain extent, it is still inseparable from the dependence on the characteristics of crops themselves. At present, a new idea of agricultural development biological agriculture is quietly rising. It realizes the purpose of artificial food production through the cultivation of biological tissue in the laboratory, which is a completely innovative form of agricultural development

the production of single-cell protein through non-agricultural means is one of the ways to solve the human demand for protein. Single cell protein, commonly known as candidate meat, is a microbial food. Microorganisms are mostly single cells, which are the entities of nucleic acids and proteins. Using fermentation to produce this unicellular microorganism can get extremely rich single-cell proteins. The reproduction rate of microorganisms is amazing. 500 kg of live bacteria can produce 1250 kg of single-cell protein in a day and night under suitable conditions; A cow weighing 500 kg can only synthesize 0.5 kg of protein per day. The main ingredients of meat are protein, fat, sugar, vitamins and minerals, and its nutritional value is comparable to that of milk and eggs. The nutritional value of 1 ton of microbial protein is equivalent to 2.1 tons of lean meat or 3 tons of eggs or 12 tons of milk. It can be used as both food and feed

algae is the leader in the microbial world. It can photosynthesis in the sun with carbon dioxide as the nutrient like higher plants, but its growth rate is dozens of times larger than that of higher plants. The algae powder harvested in a lake the size of an mu of land is converted into air, water and sunlight to produce food, which shows a broad prospect

on August 5, 2014, the world's first test tube hamburger was launched in London, the capital of the UK. This hamburger beef patty was developed by Dutch researchers from bovine stem cells and cost as much as 325000 US dollars. This is the result of years of research by mark post of Maastricht University in the Netherlands. He led researchers to isolate stem cells from bovine muscle tissue and put them into nutrient solution to promote cell growth and reproduction. The number of these stem cells exceeded 1million after three weeks. Researchers put them into several small containers, and the cells synthesize shredded meat about a centimeter long and a few millimeters thick. Researchers collect shredded meat, make small meatballs and freeze them, so as to make up enough for a piece of meat pie

perhaps in the near future, human beings will no longer need to rely on soil fertilizer, water, air, sunlight and various crops to produce food, but will directly realize customization and mass production in the factory workshop like producing toys and clothes. In this way, even if human beings migrate to interstellar space or other planets in the future, they can still produce food anytime and anywhere through industrialized production. When the technology further develops and matures, maybe we can all make food for ourselves
