Under the influence of factors like labor shortages, rising demands for industrial upgrades, and rapid advancements in cutting-edge technologies, agricultural robots are expanding their applications at an impressive pace. Today, these robots are not only becoming more diverse and intelligent but also driving the concept of "unmanned farms" into reality. The future of this industry looks incredibly promising.

The development of technologies such as artificial intelligence, big data, and the Internet of Things is transforming the agricultural landscape. Farming is moving from mechanization to digitalization, with precision agriculture quietly reshaping traditional practices. We are now entering a high-level intelligent phase in farming.
As a result, agricultural robots are playing a crucial role in the evolution of "smart agriculture." They are being used to automate tasks like sowing, planting, weeding, harvesting, sorting, and packaging. These robots are widely applied in areas such as autonomous tractors, drones, material handling, crop management, soil monitoring, and livestock operations.
Japan leads in agricultural robotics
Japan is at the forefront of agricultural robot research and development. With a shrinking population and an aging workforce, Japan faces a severe labor shortage in agriculture. Currently, only about 1.59 million people are engaged in farming, with an average age of around 67 years. This has pushed Japan to invest heavily in agricultural automation.
Japanese companies have developed robotic tractors that can operate alongside humans, increasing efficiency by up to 50%. Kubota, Japan's largest agricultural machinery manufacturer, has created a prototype for an automatic rice tractor equipped with GPS technology. It can till and fertilize based on soil conditions. Additionally, they are working on wearable devices to assist farmers in harvesting fruits and vegetables.
The Ministry of Agriculture, Forestry, and Fisheries hopes these wearable robots will support elderly and female farmers in managing difficult-to-automate fields. Other developments include automated combine harvesters and transplanters.
Agricultural robots in Europe and the U.S. set new trends
In the U.S., fertilization robots adjust nutrient application based on soil conditions, reducing overall fertilizer use and improving groundwater quality. In Germany, field weeding robots use GPS and computer systems to apply pesticides accurately. In the UK, weeding robots scan crops using cameras and image analysis, operating continuously without damaging the soil.
Spain has developed a citrus-picking robot that uses optical recognition to determine fruit maturity and timing for optimal harvests.
The concept of "unmanned farms" is gaining traction
Unmanned farms are no longer just a vision. Modern agriculture involves complex decision-making based on data, such as crop conditions, pests, and fertilization needs. Integrating advanced technologies like agricultural robots is leading the way toward fully automated farms.
At Harper Adams University, researchers have launched the "HandsFreeHectare" project, where an entire 1.5-acre field is cultivated, maintained, and harvested entirely by robots, without human intervention. Martin Abell from PrecisionDecisions said, “This project proves that there’s no technical barrier to automating farming. We’ve already done it, and our goal is to show that it’s possible.â€
Whether building smart farms or promoting drone technology, agricultural robots are central to the future of agriculture. By 2021, global sales of agricultural robots are expected to surpass 14,000 units, reaching over $2 billion. This indicates a rapidly growing market, full of potential and innovation. The field of agricultural robotics is poised to open up a new blue ocean in agriculture.
