Can Autonomous Mobile Robots Take Over Bakery Tray Transport?

Can autonomous mobile robots handle bakery tray transport on three shifts?

If your bakery runs three shifts and your pallet runners keep leaving, the work you are really staffing is tray transport: moving loaded trays from oven exits to cooling, then to packing, and returning empty racks and carts. Autonomous mobile robots can repeat that route on every shift without breaks, and they do not call out sick. They are not a fit for every step in that chain, which is why the first decision is which step to automate, not whether robots work in bakeries at all.

The question is worth asking now because the labor pool is tight across the sector. Bakeries compete for the same pool of plant workers as other food and manufacturing employers, so a vacancy can be slow to fill. A robot does not solve hiring, but it can take the repeatable part of the route off the staffing list and leave your people on the steps that need judgment.

Start by writing down the exact tray route, the shift where it fails most often and the uncovered hours in a typical week. Those three facts decide whether a robot fits, and they are the first things a site assessment will ask for.

How many bakeries and workers are in the US?

Counts vary by source. According to Vanta Insights, citing Census Bureau data rounded from 2023, there are about 9,200 bakery establishments in the US and about 87,500 workers under the retail bakeries industry code, NAICS 311811. The exact year and rounding matter, so check the official Census County Business Patterns tables before you cite a figure internally.

The scale matters for planning. Many bakery plants run a single line, while larger ones run three shifts, so your shift pattern is a real planning input and not a detail. Warehouses, distribution centers and food manufacturing plants recruit from the same labor pool, which is why the staffing gap is hard to close by raising the pay rate alone.

For you, the national count is context. The local question is whether your runner gaps fall on specific shifts, routes and days, because that is where a robot can close a gap rather than add a new cost.

Why do pallet runners and tray movers keep quitting?

The survey data points to how hard plant roles are to fill. According to Baking Business, reporting an ABA, ASB and IDDBA workforce study fielded from December 2024 to February 2025 with 80 respondents from 70 baking manufacturing companies, 43% of respondents reported machine operator shortages, up from 40% in 2016. The same study reported 60% with a high or severe shortage of maintenance and engineering staff, down from 78% in 2016.

Those shortages are not the same job as tray runners, but they show the same squeeze on the plant floor. Respondents cited a lack of qualified candidates in their area (92%) and a competitive manufacturing environment (92%). The same study reported that 14% offer transportation assistance and 4% offer childcare assistance, so most surveyed companies are not yet using those supports to keep hourly staff.

Runner turnover in particular is hard to benchmark. A packaging trade article citing the Bureau of Labor Statistics puts average annual manufacturing turnover at 19.2%, with no year given, and no bakery-specific turnover rate from BLS or a national survey turned up in this research. Pull runner turnover by shift from your own HR records, since your gaps will tell you more than any national average.

The outlook is also weak. Commercial Baking reports an ABA workforce projection headlined at 53,500 unfilled jobs by 2030, and survey respondents expect the most severe shortages to continue into 2030 among hourly and salaried roles.

What does a tray-moving robot actually do on the floor?

A tray-moving autonomous mobile robot maps the plant, follows a set route or a dispatched task, and carries a cart or rack of trays from a pickup point to a drop point. It slows or stops for people, waits at doorways, and returns to a charging point between runs. Your runners move trays, not pallets, so the load type matters: a tray and cart unit is usually a separate configuration from a pallet mover, and the integrator needs exact cart, rack and cooling-room details before quoting anything.

Safety rules shape the setup. According to ANSI, the R15.08 standard for industrial mobile robots is now complete in three parts, with ANSI/A3 R15.08-3-2026 released to cover the user side, while Part 2 on systems and applications remains edition 1 from 2023. Ask how the integrator plans against the relevant parts, how people are kept clear of the route, and how the site will document that plan.

Commissioning comes before any tray moves. Your team should walk the route with the integrator, define pickup and drop points, set stop behavior at doorways, and agree on who clears a stuck unit at any hour. Most of the risk sits in those decisions, so the commissioning plan deserves as much attention as the hardware.

Does a robot need a week-long shutdown to start?

Usually not, though it depends on the route. A phased start puts one route on one robot, runs it alongside existing runners for a defined period, and then adds the next route once staff trust the unit. That approach keeps production moving while you learn how the robot handles your real loads, shift changes and cleaning schedules.

We handle that sequence as one job. We run a free site assessment and site mapping first, then quote the lease through financing, so the cost is in writing before you commit. We deploy and integrate the robot, train your staff on the route and the recovery steps, and service it under our service plan through regional service engineers in the states we serve. We are OEM-neutral, so the unit is chosen for your route and not for one manufacturer's catalog.

Plan the cutover around your slowest hour, not your quietest. Keep a manual path open for the first weeks, and agree on a backup plan for a unit taken out of service, since one robot on one route is a single point of failure.

• Phase one: one fixed route, run alongside existing runners
• Phase two: a second route, added after a review of the first
• Phase three: coverage across all shifts, with a backup plan agreed

Where does a bakery robot struggle, and what stays with people?

Bakeries are hard conditions for any mobile robot. Trays leave ovens hot, floors near cooling and washdown areas can be wet, and loads may change after a product changeover. Tray traffic that crosses forklift lanes raises the stakes, so route design matters as much as the robot itself.

Injury data shows why reducing manual carrying is worth planning for. According to the California Department of Industrial Relations, its 2024 state table for bakeries and tortilla manufacturing reports an incidence rate of 3.3 and about 1,300 cases. The New Jersey Department of Labor reports a days-away rate of 1.9 per 100 full-time workers for the same industry code, NAICS 3118, in its 2023 incidence rates. These measures come from different years and different scopes, and no national 2024 days-away figure for the sector was found here, so use them to show direction, not as a benchmark for your plant.

People still win on unusual loads, judgment calls, hot-tray handling at the oven, jam recovery and quality checks on the way to packing. Plan those tasks as staffed roles, and let the robot take the repeatable part of the route.

• Oven unloading and hot-load handling
• Stuck-unit recovery and blocked aisles
• Quality checks and product sorting at packing

How do you decide whether a robot is the right fit?

The answer depends on a short list of facts about your floor and staffing. Gather them before you ask for a quote, so the site assessment can move faster and the quote reflects your real route rather than a generic plant.

A lease fits best when the tray route is fixed, the runner gaps are regular, and the unit can recharge in a planned window. It fits poorly when the bottleneck sits elsewhere, when cart and rack sizes change every shift, or when the floor cannot be mapped reliably. In those cases, a process change or another automation step should come first.

Financing matters too. We offer lease financing programs, with the payment set in a quote after a free site assessment, and the lease can be paired with our service plan so your maintenance team is not the only response when a unit faults. Compare that quote with the cost of open runner shifts, overtime and the training time for each new hire, using your own payroll records.

What should you measure this month before you talk to anyone?

Time your runners for one full week on each shift. Record each trip from oven exit to packing, the waiting time between trips, and the gaps when someone is out. Those figures are the baseline any robot has to beat, and they are the inputs a site assessment needs.

Also record the route layout, door widths, cooling room transitions, cart and rack sizes, and the people who would clear a stuck unit on nights and weekends. Ask two or three integrators for a site visit rather than a generic quote, and compare how each one plans the first route and the recovery steps.

If the timing shows regular gaps on a fixed route, a robot case is strong and a phased lease is a sensible next step. If the gaps come from oven loading, scheduling or packing speed, start there, because a robot placed on a slow step only moves the queue.
