Under the influence of multiple factors such as labor shortage, increasing industrial upgrading demand, and accelerated development of cutting-edge technologies, agricultural robots are rapidly expanding their application scope. Nowadays, agricultural robots are not only increasingly diversified and intelligent, but also promote the realization of new concepts such as â€œunmanned farmsâ€. The future market prospects are very broad. Today, the development of cutting-edge technologies such as artificial intelligence, big data, and the Internet of Things is changing this era. The mode of agricultural production has moved from mechanization to digitalization. Accurate agricultural technology has quietly changed the traditional mode of agricultural production, and the high-end intelligent stage has come. Therefore, in the development of "intelligent agriculture", the application of agricultural robots is becoming increasingly widespread, playing its key role to complete the arduous task of implementing automation and intelligence. At present, agricultural robots have been able to complete sowing, planting, farming, picking, harvesting, weeding, sorting, and packaging. They are mainly used in driverless tractors, drones, material management, sowing and forest management, soil management, and animal husbandry. Industry management and animal management. Japanese agricultural robots are at the forefront For the research and development of agricultural robots, Japan is at the forefront of the world. Currently, all countries in the world are facing the problem of labor shortage. Japan, which is facing the problem of population decline and aging, is even more prominent in the shortage of labor. It is understood that the population of Japan, which is mainly engaged in agriculture, has now been reduced to 1.59 million and the average age is about 67 years old. Against this backdrop, Japan has vigorously researched and developed agricultural robots. Previously, it had developed a robotic tractor that can be operated with people. The tractors work at the same time, and the efficiency is 1.5 times that of the latter. Kubota Corporation, Japan's largest agricultural machinery manufacturer, developed the first prototype of an automatic tractor for rice cultivation. This automatic tractor is equipped with a global positioning system and can arable and fertilize itself according to the soil conditions. In addition, Kubota is developing a wearable automatic device to help farmers harvest and pick fruits and vegetables. The Ministry of Agriculture, Forestry, and Fisheries hopes that this kind of backpack robot can help older farmers and women farmers to farm in fields that are difficult to use with large automation equipment. It is reported that in addition to tractors, Japan will also develop a robot version of the combine harvester and transplanter. Agricultural robots in Europe and the United States â€œlead the trendâ€ In other countries, fertilization robots developed by the United States will conduct appropriate fertilization based on actual conditions in different soils. Its accurate calculation rationally reduces the total amount of fertilization and reduces the cost of agriculture. Improved groundwater quality thanks to fertilizing science Germany's field weeding robots are based on computers, global positioning systems (GPS) and smart multi-purpose tractor integrated technologies to achieve accurate application of pesticides. The field's weeding robots in the UK use the camera scans and computer image analysis to perform weeding. It can operate continuously throughout the day and does not damage the soil when weeding. Spain's picking citrus robot, consisting of a tractor equipped with a computer, an optical vision system, and a robot, can determine the maturity of the orange from its size, shape, and color, and determine the best picking time. The concept of "unmanned farm" gradually emerged Unmanned farms are not the first time in the agricultural field. Due to its uniqueness, agricultural farming requires people to feel dark and endure the dirty and difficult work in the soil. Because modern agriculture is more complex than the agricultural model in which only crops were sown and crops were ready for ripening and harvesting again. Today, the appropriate components of different crop conditions, insecticides, weeds, and fertilizers need to be driven by data. Therefore, the comprehensive application of cutting-edge technologies such as agricultural robots and the realization of unmanned farms have become a new direction of development. Now, Harper Adams University and the researchers of the agricultural company PrecisionDecisions have studied a project called â€œHandsFreeHectareâ€, which no longer needs human intervention. On the 1.5-acre experimental field, the cultivation, care, and harvest of crops are all done by Agricultural robots finish. Martin Abell, the head of PrecisionDecisions, said: â€œThis project aims to prove that there is no technical reason why human beings are unable to cultivate their fields because we have already done so. We will look for opportunities to prove cultivation. Fields can be automated. This is the biggest success of this project." Whether building "smart agriculture" or boosting farm drones, agricultural robots are well-deserved protagonists. Data predicts that by 2021, the global sales of agricultural robots will exceed 14,000 units, and sales will exceed 2 billion US dollars. From this point of view, the field of agricultural robots has much to offer. The current market is rapidly developing or it will open up yet another new blue ocean in agriculture.
