How Autonomous Mobile Robots Can Benefit Vertical Farms

How can autonomous mobile robots for vertical farms help?

Autonomous mobile robots for vertical farms take over the repeated job of carrying plant trays between the places where crops are grown, harvested and packed. On many indoor farms that job is still done by hand, with staff pushing carts, lifting trays off racks and stacking them at stations. A robot makes the same trip on a fixed route, so growers and packers spend more of their shift on the plants and the product.

The main benefit is hours. Tray movement repeats across every shift, and it is easy to underestimate because each trip looks small. A robot that follows mapped routes removes a steady stream of walking, lifting and waiting, and it runs the same route at the start of a shift as at the end.

The category is growing, which is one reason operators are looking at this now. According to a market research report on U.S. indoor farming, greenhouses held 67% of the U.S. indoor farming market in 2025, and indoor vertical farms are projected to grow at a 12.5% compound annual growth rate through 2031. The same report, citing USDA, says controlled environment agriculture growing area rose 18% between 2022 and 2025. More growing area means more trays to move, and more trays moved by hand means more hours.

What does moving trays cost a vertical farm today?

Labor is the largest cost in most vertical farms. According to a modeling paper on arXiv, about 56% of vertical farm operating costs are labor, and roughly 15% of that labor goes to moving trays. The paper says these figures are estimates drawn from earlier work, not measured data, so treat them as a planning baseline and check them against your own records.

Other figures point the same way, though they are older or come from vendors. According to a horticulture trade article reporting a 2017 industry survey, labor was 56% of production costs for vertical farms. The same article quotes a vendor chief executive who put labor at up to 50% of operating expenses, which is a vendor claim and should be tested against your own payroll.

The headline share matters less to a grower than the hours behind it. The useful question is how many hours a week your team spends carrying trays, and how often that carrying pulls people away from crop work at the moments the crop needs them most.

Which areas of the farm does the robot work in?

Most of the robot's work happens between stations rather than inside the grow rooms. It moves trays from where seeds are started to the grow racks, from the racks to harvest, then through washing, packing and out to dispatch. Each of those points is fixed, which is what makes a mapped route practical.

The zones below are the usual places. Your list will depend on the layout, the crop mix and whether harvest and packing share a room.

Route clearance matters as much as the number of stops. Aisles must stay open for staff and carts, and every station needs a clear rule for where a tray waits when the next step is busy. A route that works on paper can still stall if a door is propped open or a cart is parked in the lane.

Start the route plan with the most repeated move, usually seed trays to the grow racks or harvested trays to the wash area, and add the others in order. A narrow first route is easier to keep clean, and it gives staff a clear way to judge whether the next route is worth building.

How does the robot work day to day?

The robot runs from a task list. A grow manager or the farm's scheduling software assigns a tray move, the robot picks up the tray at its pickup point, follows its mapped route, and sets the tray down at the target station. It then charges or takes the next job in the queue.

Setup does most of the work before go-live. Routes, stations and docking points are mapped during the site assessment, and each station is marked so the robot knows where to stop and how to approach a rack. When an aisle is blocked, the robot waits or takes a planned alternate path, and staff clear the obstruction.

People stay in charge of the crop. Staff decide what moves and when, check tray counts and step in on anything the robot cannot read, such as a damaged tray, a missing label or a rack that has been moved. The status view shows the team where each tray is, which cuts down on searching.

How many hours does a vertical farm actually run?

Published hour figures vary, partly because they describe farms at various levels of automation. A vendor research summary puts a mixed-crop farm run at capacity at about 24.6 hours a week under its standard procedures. At the other end, a New Brunswick grower reported 70 to 80 hours a week just to keep operating, and that account is anecdotal rather than a survey.

These totals cover the whole operation, not only tray moves, so they show scale rather than savings. They still matter for planning. When the whole farm runs at tens of hours a week, even a repetitive task that takes a modest share of those hours is worth measuring before you commit to a change.

The same reporting describes a grower who put the farm up for sale because of labor shortages. A farm that cannot fill shifts loses crop timing, and a task that waits on hiring is a strong candidate for a robot. That is a reason to measure now, while you still have the staff to train.

How does the robot work alongside existing staff?

The robot is not a replacement for the team. It takes the steady carrying work, while people keep seeding, crop care, harvest, packing and quality checks. The usual pattern is a robot, or a small fleet, working alongside a team that keeps its growers and packers and moves its time from hauling trays to plant work.

Training on the robot side is short. Staff learn to load and unload trays, clear a blocked route, read the status view and know when to call for help. Growers keep control of the schedule and can change a route when a new crop moves into a room, because the plan is set by the farm, not by the vendor.

Our team handles the outside work. We pick the right robot for the site, lease it through financing, deploy and integrate it, train the staff and service it nationwide. That leaves the crop decisions with your people, where they belong.

What drives the savings, and what does it depend on?

Savings come from hours taken off repetitive carrying work, so they depend on three things: how many trays move each shift, how far each tray travels, and how long stations wait for the next tray. Published estimates put tray moves at roughly 15% of labor, and labor at about 56% of operating costs. Those are starting points, and the share a robot can take is the number to measure on your own floor.

Hour ranges help you size the job. Whole-farm figures run from about 24.6 hours a week at a mixed-crop farm at capacity to 70 to 80 hours a week reported by one grower. The same robot can matter a great deal on one farm and a small amount on another, depending on where the farm sits in that range and how much of its time goes to carrying.

A site assessment turns these ranges into your numbers. We count trays per shift, measure route lengths, time the stations and note the doors and lifts on each path. The result is an estimate you can check against your own schedules, and the quote is built from it, with no savings figure promised ahead of that count.

What can an autonomous mobile robot not do in a vertical farm?

A tray robot does not grow, seed, harvest, trim or pack. It cannot judge plant health, spot a pest on a leaf, or decide that a rack needs more light. Those tasks stay with people, and a farm that expects the robot to cover them will be disappointed on the first busy day.

Layout is a real limit. Routes need clear floors and surfaces the robot can drive on, aisles must stay open, and a rack that moves often needs to be remapped. Doorways, freight lifts and elevators have to be measured first, because the robot cannot use a path it cannot fit through.

Downtime planning matters too. A robot that is charging or waiting for service is not moving trays, so keep a manual plan for peak days and a fallback for each route. Expect the robot to handle the repeated carrying work well, and expect people to handle the exceptions, which is the split the plan is built around.

How do you get started with autonomous mobile robots for vertical farms?

Start with a free site assessment. We walk the farm, map the rooms and stations, count tray moves across a typical shift, and note the doors, lifts and aisles each route must use. From that work we lay out the route set and the robot that fits it, in writing.

Robots are leased through financing, and the payment comes in the quote after the site assessment. The quote sets out the lease terms, service coverage and go-live timeline for the units in the plan. A common first step is one leased unit on the busiest route, then more units once the routes prove out on the floor.

After signing, we handle deployment and integration, go-live support and staff training. The service line stays open after go-live, and nationwide service means a technician can be dispatched when a unit needs attention. Plan the first week with your growers so the routes are clean before the busiest harvest days.

Bring three things to the assessment: a rough count of trays per shift, a floor plan with doors and lifts marked, and the names of the people who will work with the robot each day. Those items let the assessment move quickly and keep the first plan close to how your farm already runs.
