Arabfields, ilhem Saàdoun, Correspondent, Kobe, Japan — A Japanese robotics manufacturer has joined forces with the country’s agricultural cooperative sector to develop AI-powered machines capable of harvesting crops autonomously, as Japan looks for ways to address a growing shortage of farm workers.
Yaskawa Electric and the National Federation of Agricultural Cooperative Associations have developed a robot designed to identify mature produce and pick it without continuous human supervision. The machine began operating at a farm in Saga Prefecture, southwestern Japan, in 2026, marking a practical step towards introducing artificial intelligence into everyday agricultural work.
Unlike conventional automated equipment programmed to perform repetitive movements, the robot uses physical AI to assess crops and determine whether they have reached the appropriate size for harvesting. The technology is intended to help machines respond to changing conditions in the field rather than simply follow fixed instructions.
The system addresses a pressing challenge for Japan’s agricultural industry. An ageing farming population and a shrinking workforce have made it increasingly difficult for producers to find enough workers during busy harvesting periods. For farms growing labour-intensive crops such as cucumbers, delays in picking can affect product quality, sales and profitability.
The robot can currently harvest approximately 120 cucumbers in 40 minutes, according to Yaskawa Electric. Although the performance demonstrates that autonomous harvesting is possible, the company acknowledges that the machine must become faster before it can match the productivity of human workers.
Matsuura Hidenori of Yaskawa Electric said the ability to operate at night could provide an important advantage, particularly when workers are unavailable. He added that the company was focusing on improving the robot’s ability to understand farmers’ needs.
For growers, the potential benefits extend beyond reducing dependence on seasonal labour. Autonomous robots could help farms maintain harvesting schedules, operate for longer periods and allocate human workers to tasks requiring more complex judgement. However, practical adoption will depend on reliability, maintenance costs and the ability of machines to handle variations in crop size, lighting and growing conditions.
The technology also illustrates a broader shift in agricultural automation, with manufacturers moving from machinery that assists human operators towards systems capable of making decisions and carrying out physical tasks independently. Advances in computer vision, sensors and AI models are making it increasingly possible for robots to distinguish ripe produce from crops that need more time to grow.
Nevertheless, commercial deployment presents challenges. Cucumbers and other delicate crops must be picked without bruising or damaging the plant, while robots need to navigate crowded growing environments and maintain consistent performance throughout a working day. Equipment costs could also limit adoption among smaller farms unless productivity gains justify the initial investment.
Looking ahead, Yaskawa’s stated goal is to bring the robot’s harvesting performance up to the level of human workers. Achieving that target could make autonomous harvesting more attractive to commercial growers, particularly where labour shortages are severe and crops require frequent picking.
If the technology proves reliable and economically viable, similar systems could eventually be adapted for other labour-intensive crops. Wider adoption will depend on further field testing, lower operating costs and the ability to demonstrate measurable benefits for farmers.
For Japan’s agricultural sector, the project offers a glimpse of how robotics could help preserve production capacity as the workforce contracts. The next test will be whether the machine can move beyond promising trials and deliver the speed, precision and affordability needed for routine use on farms.
