The question
Our paper mill in Berlin, New Hampshire has finished rolls sitting two days in the yard because only two stackers know the routes, and the trucks keep waiting; could autonomous mobile robots move rolls to the truck bays?
The short answer
For most of this job, yes: autonomous mobile robots can move finished paper rolls from the yard to the truck bays, and they can carry the stackers' route knowledge in a stored map instead of in two people's heads. The fit depends on three things a robot does not settle by itself: a cleared, mapped path from storage to every bay, roll handling equipment matched to your roll weights and cores, and a link to the list that tells the yard which truck loads next. If the yard is unpaved, poorly plowed through a Berlin, New Hampshire winter, or needs a crane or overhead lift to set rolls, a mobile robot is the wrong first machine, and a site assessment should test the routes before anything is leased.
Key takeaways
- A mobile robot can only follow routes that someone has mapped and written down, so the stackers' knowledge comes first.
- Roll handling equipment matters as much as the robot, so test the attachment on your actual rolls and cores.
- Berlin winters decide the yard surface plan, so check snow and ice routes before committing to a lease.
- Trucks wait on loading and dispatch as well as on moving speed, so link the robots to the truck schedule.
- Start with one lane and one truck bay, then widen only after the routes hold through a full winter month.
Can mobile robots move paper rolls in Berlin, New Hampshire?
Berlin is the only city in Coös County, and its mill history shapes the labor pool a paper mill in Berlin, New Hampshire can draw from. The pulp mill closed in March 2006 and 250 employees were displaced, according to the Wikipedia article on Berlin, New Hampshire. Some of those workers moved to a paper finishing operation, which shows that a mill's experienced people are a local resource that can move, retire, or leave.
The state labor office reports unemployment at 7.7% in 2009 and 3.8% in 2019, according to the New Hampshire Employment Security community profile for Berlin. Its 2023 local area table put the Berlin micropolitan area at about 2.0%, with monthly estimates roughly between 1.8% and 2.4%. I could not find a 2026 Berlin or Coös County unemployment figure or a mill headcount for this year, so treat the labor picture as background and not a forecast.
A small local labor market makes a single stacker hard to replace. When the two people who know the routes leave, the yard knowledge leaves with them, so the fix has to live in a map and a set of rules instead of in memory. Our free site assessment starts with that question: which yard routes carry the rolls, and which of them a robot can run without a person in the path.
Why do finished rolls sit in the yard for two days?
Rolls that wait two days with trucks idle are usually a sequencing and knowledge problem before they are a moving problem. Rolls wait when nobody is sure which bay is free, which stack is clear, or which lane avoids a blocked aisle, and the people who hold those answers become the bottleneck. A robot will not fix a sequencing gap on its own, but it removes the yard leg from the list of tasks that depend on two people.
The occupation is large but it is not the same as a yard crew. The Bureau of Labor Statistics put pulp, paper, and paperboard mills at about 24,180 workers in paper goods machine setters, operators, and tenders in May 2023, and converted paper product manufacturing at about 63,660, according to its May 2023 occupational estimates. Those counts describe the job code, not who knows your yard, and the BLS estimates I checked do not give a turnover rate, so use your own roster and separation records.
The practical test is simple. Time one roll from the moment it is finished to the moment it is loaded, and note where it stopped and who it was waiting for. If most of that time is spent waiting for a person to move it, a robot helps. If it is spent waiting for a truck or a loading crew, a robot will only move the queue closer to the door.
Can a mobile robot handle paper rolls the way a forklift handles pallets?
Paper rolls are not pallets. They are cylinders that must be cradled, clamped, or set on end, and the roll diameter, core, and weight decide the handling method. A robot built for pallets may need a different attachment before it can lift rolls cleanly, so the test has to use your actual rolls, not a sample pallet or a clean stock roll.
Powered equipment is the reason many mills want people out of the lanes. The National Safety Council linked forklifts to 84 work-related deaths in 2024 across all industries, and it counted 25,110 DART cases for forklifts across 2023 and 2024 combined, meaning cases with days away from work or restricted duty, including 15,460 days away cases. The council also notes that BLS changed its event classification starting with the 2023 data year, so those figures are not a clean trend line.
A Forest Products Journal study of OSHA severe injury records for wood and paper manufacturers from 2015 to 2019 found 17 fatalities and 211 severe injuries over those five years. The most common forklift events were overturns, pedestrians struck, and workers crushed. A mapped route only removes those risks where the crossings are designed in, so the site assessment should mark every place a walkway meets a lane.
How do the stackers' routes become a map a robot can follow?
A robot follows the map and the rules you give it. The two stackers' knowledge is the source material: which lanes are clear at shift change, which stacks can be reached from only one side, which bays take which roll sizes, and which shortcuts are only safe in daylight. Writing that down is most of the work, and it is worth doing even if you never lease a robot.
During deployment the site is mapped, the routes are set, and the dispatch rules are tied to whatever tells the yard which truck is loading. We integrate the robots with that list, so a finished roll can be assigned to the next open bay without a phone call. Go live support stays on site through the first shifts, and the rollout can be phased so the yard keeps running while the routes are tested.
Blocked routes are where mapped robots stop. A parked trailer or a stack set in the wrong place halts a unit until someone clears it, so the map has to include the yard's real habits, not just the drawing. Each exception should have an owner, a clear way to report it, and a rule for when a route is closed.
What does a Berlin winter do to a yard robot plan?
Winter is the design input most likely to change a yard plan. According to a climate listing built on 1991 to 2020 normals, January average highs sit near 26°F and lows near 5°F, while February highs sit near 30°F and lows near 7°F. Other climate sources report colder and snowier figures for the same town, so check the exact normals with the National Weather Service before anyone sets a design temperature.
Snow and ice change three things: traction on outdoor paths, sensor reliability when snow or frost covers a unit's sensing surfaces, and how long a cleared path stays cleared after plowing. A route that works in October can fail in February. Plan either a winter route set and a summer route set, or one set that includes plowed lanes and a covered approach to the truck bays.
Cold also shapes charging and idle time. Charging locations need to sit where snow does not block them and where a waiting unit does not sit in a truck lane. The site assessment should settle who clears snow from the robot lanes, so nobody assumes the plow crew will keep them open without an agreement.
Will trucks load faster if rolls reach the bays sooner?
Only if the bay is ready. Rolls that reach the bay early still wait if the loading crew is short or the truck is not on the schedule. A robot shortens the yard leg, and the rest of the wait belongs to dispatch and bay staffing. Time both before you commit to any lease.
Demand for this kind of automation is rising. The International Federation of Robotics counted 102,900 transportation and logistics service robots sold in 2024, up 14%, and attributed the growth largely to staff shortages, according to trade press coverage of its World Robotics 2025 report. Those are service robots, mostly mobile units that move and handle goods, so the figure shows the category is growing, not how a particular yard will behave.
Start with a question the figure cannot answer: how many truck loads per shift are waiting on yard moves, and how many are waiting on people at the bay. Your own timestamps answer that faster than any industry number, and they give you the baseline you need to judge a pilot.
Where does a person still win over a robot?
People win on exceptions. A stacker can see a split core, a damaged wrap, or a leaning stack and reroute around it without asking anyone. A robot will stop and report the exception, and someone still has to clear it. Keep experienced stackers on exceptions and on the map, not on every routine move.
A robot wins on repetition, hours, and memory. It runs the same route at the same pace on the second shift as on the first, and it does not need the route explained again when someone is out sick. It also logs every move, which helps when a truck is held and someone asks why.
The honest answer for most mills is a mix: robots for the repeated yard legs on mapped routes, and people for loading, exceptions, and unmapped corners. A pilot on one lane shows which mix you need before you widen the fleet.

How do you lease, deploy, and service one with us?
We start with a free site assessment. We walk the yard, measure the routes, test your rolls on the handling attachment, and map the paths a robot would take. The fixed robot lease payment is quoted after that assessment, so the quote reflects your routes and not a guess.
Robots are leased through financing, so you are not carrying the full equipment cost up front. We pick the right units across manufacturers, deploy and integrate them with your truck schedule, and train the stackers and every shift on the map and on exception handling. Every unit is then serviced under our service plan.
Service runs on on-site dispatch and remote triage, backed by regional service engineers in every state we service. You can start with one leased unit and a backup robot program, then phase in more units without shutting the yard. Ask for the lease quote with service included, so you compare the full arrangement and not the equipment alone.
What should you check before you decide?
Confirm the facts that would change the answer before anything is leased. A fit that looks good on a drawing can fail on a snowy morning or with a split roll in the lane. Five checks settle most of the question, and they are listed below.
Then decide the scope. Start with one lane and one truck bay, measure wait time before and after, and widen only when the routes hold through a full winter month. If the yard needs a crane or a clamp lift at the stack, the next step is a different machine, and the assessment will say so plainly.
Bring the two stackers into the assessment. They know more about the yard than any drawing does, and their map is what makes a robot fit.
