Precision and Sustainability in Each Drop: Inside ...

Farmers face a troublesome mixture of challenges: there aren’t all the time sufficient employees to have a tendency huge orchards, and those that spray pesticides danger harming their very own well being by inhaling poisonous chemical compounds. On the similar time, overusing sprays pollutes soil and water, threatening each the setting and the long-term well being of crops and folks. 

Enter Purida, a next-generation orchard spraying robotic constructed to chop chemical use and defend each individuals and the planet. Mounted on an all-electric, light-weight body, Purida drives itself by means of rows of fruit bushes and applies pesticides solely the place they’re wanted. It will probably cowl extra floor in much less time, then mechanically return to its base when the job is completed 

At its core, Purida makes use of AI-based autonomous driving, electrostatic nozzles, and a sensible blower system. GPS, LiDAR, and imaginative and prescient sensors work collectively so the robotic navigates difficult terrain and avoids obstacles. 

Its electrostatic nozzles cost spray droplets in order that they cling evenly to each side of leaves, chopping pesticide use by as much as 40 %. A separate blower at every nozzle lets Purida regulate airflow for various crops—whether or not apples, pears, or grapes—guaranteeing exact protection with out waste. It is a game-changer.

Historically, orchard managers relied on guide or tractor-towed sprayers. Employees with backpack sprayers spray by hand, which is sluggish, uneven, and exposes them to chemical compounds. Bigger tractors pull growth sprayers, however they nonetheless drench whole canopies and lose 65 %–70 % of spray to float and runoff. Many growers additionally comply with inflexible spray calendars, making use of chemical compounds whether or not illness danger is excessive or not, resulting in pointless environmental hurt.

Purida makes use of AI to stay steady on tough orchard flooring. An AI continually watches the way it strikes and reacts earlier than hassle begins. Tiny gyroscopes and accelerometers feed a neural‐community mannequin working on the robotic’s onboard pc with actual‐time knowledge about tilt, velocity, and path. 

That AI has been skilled on hundreds of examples of secure and unsafe slopes, so if it spots patterns that normally result in tipping, it immediately slows or stops the robotic. All of this occurs within the blink of an eye fixed, maintaining Purida from leaning too far and risking a rollover even when the bottom is uneven. Purida has been optimized to keep away from floor root harm.

Behind the scenes, Purida additionally builds a dwell map of the orchard utilizing GPS, LiDAR, and cameras. This “floor‐adaptive” navigation layer updates repeatedly, marking spots the place the soil dips or banks too sharply and steering the robotic round them. By weaving collectively quick sensor suggestions, predictive AI, and adaptive path planning, Hada makes positive Purida can spray each row rapidly and exactly, with out ever shedding its steadiness.

HADA has already moved Purida out of the lab and into actual orchards. Since early 2025, the corporate has equipped Purida items to industrial farms by means of Korea’s government-backed New Expertise Distribution Venture, working pilot trials on apple and grape orchards. 

Early suggestions from these on-farm pilots has been overwhelmingly constructive. Growers report that Purida’s autonomous path planning and remote-monitoring app allow them to deal with spraying with a fraction of the crew they as soon as wanted. 

In addition they reward the electrostatic nozzles for delivering extra even protection with noticeably much less drift, and so they’ve been impressed by the robotic’s rock-steady stability on uneven terrain, particularly when in comparison with tractor-towed booms. For a lot of, essentially the most vital aid has been understanding they not have to face shoulder-to-shoulder with a dwell sprayer, inhaling high-quality mist each time they deal with their bushes

Purida is constructed by Hada Co., Ltd., a Korean agency that has specialised in field-crop equipment since 2012. From their begin constructing garlic planters, they’ve grown into an built-in options supplier combining in-house {hardware}, software program, and AI experience. Immediately, they’re the one Korean firm with any such industrial orchard spraying robotic—and so they’re transferring quick to develop globally, with plans to point out off their subsequent mannequin at CES 2026.
