About the AVO Autonomous Weeding Robot
The AVO from ecoRobotix is a lightweight autonomous weeding robot that navigates row crops on its own, using cameras and image-recognition software to detect weeds and treat them individually. Rather than spraying an entire field, the robot’s precision spraying arm applies a micro-dose of herbicide directly onto each detected weed, cutting chemical volumes by up to ninety percent compared with broadcast application. Its low weight limits soil compaction, and solar panels on the roof supplement the battery system to extend operating hours through long summer days. The AVO follows crop rows using vision guidance and RTK positioning, plans its own field coverage, and returns to base when the job is done or when it needs attention. Developed in Switzerland and deployed across European farms, it suits sugar beet, rapeseed and other row crops where early-season weed control determines final yield. For growers facing herbicide restrictions, resistance pressure and sustainability targets, the AVO offers autonomous weed management that dramatically reduces chemical input while keeping fields clean from emergence through canopy closure, all without tying up a tractor or a driver.

Ultra Low Volume Spraying
The AVO’s core value is applying herbicide only where a weed physically exists, drop by drop. Conventional broadcast spraying treats every square metre of a field regardless of need, while the AVO’s vision-guided arm doses each weed individually, reducing total chemical volume by as much as ninety percent. That reduction flows straight to the bottom line as lower chemical purchasing costs, and it dramatically cuts the farm’s environmental footprint. Fewer litres applied means fewer spray passes with heavy equipment, less drift risk near watercourses and easier compliance with tightening European pesticide regulations. For farms in catchment-sensitive areas or under chemical reduction schemes, the documented micro-dosing approach provides defensible evidence of genuine input reduction.
Early Season Weed Control
Weeds that establish in the first weeks after crop emergence cause the most yield damage, and the AVO is built for exactly that window. The robot can begin working as soon as rows are visible, detecting and treating weeds while they are small and easiest to kill. Because it operates autonomously, it does not wait for a tractor driver during the busy spring period, and its light weight lets it enter fields earlier after rain than a heavy sprayer could. Consistent early control keeps the crop ahead of weed competition through the critical establishment phase. The robot can make repeated passes as new flushes germinate, maintaining a clean field until the crop canopy closes and naturally suppresses later weed growth.
Soil Health Preservation
Heavy spray equipment compacts soil and damages the structure and biology that drive nutrient cycling, and every avoided pass pays dividends for years. The AVO weighs a fraction of a self-propelled sprayer, so its wheels leave minimal impact even on softer ground. Its precision treatment also means the soil microbiome is not repeatedly bathed in herbicide, preserving beneficial fungi and bacteria that support crop health. Reduced compaction improves water infiltration, root penetration and drought resilience across the whole rotation. For farms investing in regenerative practices and soil health scores, the AVO aligns weed control with the broader goal of treating soil as a living asset rather than an inert growing medium.
Autonomous Coverage Of Large Fields
The AVO plans and executes complete field coverage without human steering, following crop rows with its vision system and correcting position with RTK guidance. Operators define the field boundary and crop parameters, then monitor progress remotely while the robot works systematically through the area. When the tank runs low or a fault occurs, the machine stops safely and alerts the operator rather than continuing incorrectly. This autonomy converts weeding from a labour-intensive tractor task into a supervised background process, freeing skilled staff for work that genuinely needs human judgement. Multiple fields can be treated in sequence across a week, giving mid-sized farms a level of weed-control consistency previously available only to operations with dedicated spray crews.
Frequently Asked Questions
How much herbicide does the AVO save?
ecoRobotix reports reductions of up to ninety percent in herbicide volume compared with broadcast spraying, because the robot applies micro-doses only onto detected weeds. Savings vary with weed pressure but are substantial in virtually all conditions.
Which crops does the AVO support?
The robot is designed for row crops including sugar beet, rapeseed and similar plantings. Its vision models identify crop rows and distinguish weeds within them across the early growth stages where treatment matters most for final yield.
How is the robot powered?
The AVO runs on batteries supplemented by solar panels on its roof. The solar contribution extends daily operating hours, particularly during the long sunny days of the main weeding season, reducing charging stops and increasing daily coverage.
Does it need constant supervision?
No. The robot navigates and treats autonomously after the operator sets field boundaries and crop parameters. It alerts the operator if it needs attention, such as a tank refill, and stops safely rather than continuing with a fault.
Will it compact my soil?
The AVO is deliberately lightweight compared with tractor-drawn or self-propelled sprayers, so its impact on soil structure is minimal. It can also enter fields sooner after rain than heavier machinery, extending the workable window.
How does it navigate the rows?
The robot combines camera-based row following with RTK satellite positioning. The vision system tracks crop rows visually while RTK provides centimetre-level absolute position, giving reliable guidance even when plants are small.
What happens when the tank is empty?
The AVO monitors its tank level continuously. When the spray tank runs low, it pauses and alerts the operator or returns to base for a refill, then resumes the treatment map from exactly where it stopped.
Is it suitable for smaller farms?
Yes, its autonomous operation and modest size suit mid-scale farms that cannot justify self-propelled precision sprayers. The labour savings and chemical reduction make the economics work at smaller scales than heavy machinery requires.
