An AGV warehouse is most effective when automated guided vehicles fit the work already moving through the building. Before selecting vehicles, map where loads start and finish, how often each transfer occurs, where people and other equipment cross the route, and how goods are handed off. Then test whether the storage layout, travel paths, charging arrangements and warehouse systems can support that flow during busy periods as well as normal operations. AGVs can reduce repetitive manual transport, but they cannot resolve poor slotting, congested aisles or unclear work priorities by themselves. Plan the whole process first, and use a pilot to confirm that the proposed system works in the real operating environment.
List the transfers you expect an AGV to perform. Typical candidates include moving pallets from receiving to a staging area, replenishing pick locations, transferring loads between storage and production, or taking completed orders to dispatch. For each movement, record the origin, destination, load type, frequency, timing requirements and handoff method.
Separate regular, repeatable transfers from irregular work. A predictable pallet movement between two well-defined points may be easier to automate than a task with frequent changes in load size, destination or priority. That does not rule out automation for variable work, but it may call for a different vehicle, navigation method or level of system integration. Identify exceptions early rather than treating every transfer as an identical trip.
Use operating data where it is available. Warehouse management system records, dispatch logs and observations on the floor can reveal where trips occur, when demand peaks and how often loads wait at handoff points. If the data is incomplete, collect a representative sample across different shifts and operating conditions. A design based only on an average day can leave too little capacity for peak periods.
Draw proposed AGV paths onto a current floor plan, then walk the routes in the facility. Include pickup and drop-off points, waiting areas, crossings, aisle entries, doorways and any place where vehicles must turn or pass one another. A route that looks direct on a plan may be impractical if it conflicts with forklift movements, pedestrian access or a busy picking face.
Look closely at intersections and shared aisles. Several routes converging at one cross-aisle can create queues even when each individual journey is short. A vehicle may also block a narrow aisle while waiting for a load, a door or another machine. Depending on the site, useful responses can include separating inbound and outbound paths, changing the order of stops, adding a controlled waiting location, or moving a handoff away from a high-traffic area.
Route rules need to reflect work priorities. If replenishment, production supply and dispatch staging all compete for the same vehicles or corridor, decide how the system should sequence them. Without defined priorities, urgent jobs can be delayed behind less time-sensitive moves, or vehicles can repeatedly travel through the same congested zone.
Some AGVs follow defined paths or guidance points; other systems can adjust their paths within a mapped operating area. Product terminology varies, and labels alone do not tell you how a specific vehicle will behave around obstacles, route changes or traffic. Ask suppliers to demonstrate the actual navigation and traffic-management functions against your proposed floor plan.
Storage density and vehicle access must be planned together. A layout may provide more pallet positions but leave insufficient working space for the vehicle to approach, turn, lift or deposit a load. Check aisle widths, rack ends, column locations and approach angles against the selected vehicle’s documented operating requirements. Do not assume that a route suitable for a person-operated forklift will work for an AGV.
Confirm that the load presentation is consistent enough for automated pickup. Pallet condition, load overhang, wrapping, fork entry and load stability can affect whether a transfer succeeds. Where the vehicle interfaces with conveyors, lift tables, automated doors or other equipment, define the physical and control handoff: where the load stops, how its arrival is detected, and what happens if the receiving point is occupied.
Storage policies matter too. If putaway locations change frequently, the system needs a reliable way to communicate the destination and update inventory records. If pick faces are replenished only when an operator notices a shortage, an AGV may be available but still wait for a task. Align task creation and release with the replenishment process rather than expecting the vehicle to fix gaps in warehouse discipline.
| Flow situation | Planning response | Risk to check |
|---|---|---|
| Repeated transfers between fixed points | Define a clear route, pickup point and delivery handoff. | Queues may form if several jobs share one aisle or destination. |
| Multiple routes crossing at a busy junction | Review route priority, crossing control and possible waiting space. | Vehicles can block one another or interrupt manual traffic. |
| Replenishment beside active pick faces | Plan delivery timing and a safe, usable drop location. | A delivery can obstruct picking or arrive before space is available. |
| Variable loads or changing destinations | Specify acceptable load conditions and how tasks are assigned. | Exceptions may lead to failed pickups or staff intervention. |
Fleet sizing should be based on complete task cycles, not just distance travelled. A cycle includes travel to the load, pickup, travel to the destination, drop-off and any time spent waiting for access or confirmation. Add the effects of charging, planned downtime and operational variation. If those elements are missing, a calculation may suggest fewer vehicles than the workflow can reliably support.
Start by estimating the workload for each period you need to serve, especially the busiest normal shift. Compare that workload with the productive time available from each vehicle under the proposed route and handoff design. Treat the result as a planning estimate, not a guaranteed fleet count: congestion, task variation and unplanned stops can change actual capacity.
Ask the supplier to explain the assumptions behind its capacity estimate. Check whether the calculation includes real aisle conditions, pickup and drop-off times, charging strategy, traffic controls and the performance of connected equipment. If you cannot supply reliable figures, test the estimate with a pilot or a measured simulation using representative operating data.
Charging is part of the workflow, not an afterthought. Decide where vehicles will charge, how charging will be scheduled and how the fleet will maintain coverage while vehicles are unavailable. The charging area must not obstruct routes, storage access or other work. Confirm the proposed arrangement against the chosen vehicle’s requirements and your operating schedule.
AGVs share space with staff, forklifts and other equipment in many warehouses. Map pedestrian crossings, doors, blind corners and areas where people regularly leave the marked walkways. Decide how those interactions will be managed through route separation, access controls, warning systems, operating rules or a combination of measures appropriate to the site.
Review the full operating environment with the supplier and the people responsible for workplace safety. Relevant conditions may include floor quality, gradients, thresholds, lighting, dust, changing obstacles and access to emergency routes. Verify the vehicle’s documented operating limits rather than assuming it can handle existing floor or access conditions. Any proposed route must preserve required access and must not turn a safety exit or essential aisle into a parking or waiting point.
Set out what staff should do when an AGV stops, a load is damaged, a route is blocked or a system alarm appears. Include training, escalation, recovery and restart procedures. A system that works only when every route is clear and every load is perfect needs a defined exception process before it is introduced.
An AGV needs reliable instructions about what to move, where to collect it and where to deliver it. Establish which system creates and prioritises tasks: this may involve a warehouse management system, a fleet manager, a warehouse control layer or a combination of these. Confirm how task status, load identity, location and completion are recorded so that inventory and physical stock do not drift apart.
Map the exchanges between systems before procurement. For example, determine how a replenishment request becomes an AGV mission, how the vehicle knows the assigned pickup, and how the destination confirms receipt. Plan what happens when a destination is full, a scan fails, a job is cancelled or communication is lost. These cases are operational requirements, not minor details to leave until commissioning.
Include other equipment in the integration review. Conveyors, automatic doors, lifts, charging points and safety controls may need to exchange signals or follow coordinated sequences. Name the party responsible for each interface and test those interactions as part of the acceptance process.
Set success measures before the pilot begins. Useful measures may include completed transfers, task waiting time, manual interventions, delivery accuracy and the effect on staff workload. Choose measures that reflect the problem the project is meant to solve. A high number of vehicle movements does not prove that the warehouse is handling more work effectively.
Good candidates often involve repeated movements between known locations with a consistent load and a clear handoff. Examples include pallet transfers, replenishment or supply movements where the route and destination can be defined. Irregular tasks may still be candidates, but they require closer review of load variation, task assignment and exception handling.
AGV commonly describes a vehicle operating with defined guidance or routes, while AMR is often used for vehicles that can choose or adjust paths within a mapped area. The terms overlap in the market, so compare the actual navigation, obstacle response, traffic management and route-change functions rather than relying on the label.
They may be designed for shared operating environments, but the layout and work rules need to account for interactions with people and other vehicles. Assess crossings, blind areas, access restrictions, warning methods and recovery procedures with the supplier and the site’s safety personnel. The right controls depend on the specific vehicle and facility.
There is no useful fleet count without knowing the task volume, route time, handoff delays, charging plan and operating peaks. Build an estimate from complete task cycles, then validate its assumptions with a supplier or pilot. A design based on average demand alone may not cover busy periods reliably.
Not necessarily, but the current layout should be tested against vehicle access, load handoffs, traffic and storage requirements. The review may show that only a few routes or staging points need to change, or that wider workflow adjustments are necessary. Make those decisions before installation so the automation is not fitted around avoidable bottlenecks.
For an effective AGV warehouse, begin with measured material flow and design routes, storage access, handoffs and system behaviour as one operating plan. Verify safety and capacity assumptions, then use a representative pilot to find problems before expanding. The next practical step is to map one high-volume transfer from pickup to delivery and test whether the proposed route works during a busy shift.
