AMR vs AGV: Choose the Material-Flow Architecture
Compare AMRs and AGVs through routes, load transfers, fleet control, site changes and acceptance tests. Use the actual transport workflow instead of a technology label to choose.
Start with the delivery requirement
An AMR or AGV project should begin with the movement that needs to happen: what load, from which station, to which destination, how often and under what constraints. The useful comparison is between complete material-flow architectures. A navigation label alone does not tell you how pallets are transferred, how jobs are dispatched or how a stopped vehicle is recovered.
Measure the current process over representative shifts. Record waiting, loading, travel, unloading and empty returns separately. Include peak periods and unusual loads. This baseline makes it possible to compare different proposals against the same operational problem.
Understand the usual navigation distinction
MiR's comparison describes traditional AGVs as following predefined paths and AMRs as using more flexible navigation. This is a manufacturer's explanation, not a complete taxonomy or an independent claim that every AMR is safer or cheaper. Real proposals can use virtual routes, physical guidance, mapping and traffic rules in different combinations.
Ask the supplier to demonstrate route creation, response to an obstruction and the procedure for changing a destination. A system that can plan another path still needs an acceptable alternative route. Its ability to navigate does not remove congestion, access restrictions or the need to protect people.
Compare the whole load-transfer cycle
Document the load carrier and transfer method: cart towing, under-rack lifting, pallet handling or conveyor transfer. Check the combined vehicle and load envelope, positioning at the station, load retention and the process for confirming a successful handoff. A high vehicle payload does not establish compatibility with every rack, pallet or centre of gravity.
Specify normal and peak jobs per hour, including empty returns.
Identify station queues, buffer capacity and priority rules.
Describe manual loading effort and the response to misplaced loads.
Include charging, recovery and maintenance in the capacity assessment.
A short driving demonstration can miss the station or handling delay that dominates the real process.
Evaluate fleet and business-system integration
OMRON MobilePlanner illustrates a fleet interface showing locations, battery levels, jobs and alerts. The practical question is which functions the offered system provides, who operates them and what connects them to the customer's production or warehouse software.
Request an interface schedule covering job creation, cancellation, completion and error states. Ask how priorities change, how traffic is coordinated and what happens during a network interruption. Confirm whether fleet licences, servers, interfaces and support are included. Do not assume different brands interoperate because both products are called AMRs.
Assess site suitability and change effort
ISO 3691-4:2023 includes both AGV and AMR examples within its driverless industrial truck scope. The relevant safety assessment is therefore not decided by choosing one label. Have qualified parties review the actual machine, load, operating zone and intended use.
Compare the work needed to introduce a new route, add a station or change the product mix. Include mapping, guidance changes, system configuration, operating-zone review and staff instruction. Flexible routing may be valuable in a changing layout; a stable, repetitive route may favour a different design. Test those assumptions with your own operating conditions.
Choose through a representative pilot
Run candidate systems against the same task list, loads, route constraints and acceptance criteria. Measure completed useful jobs, waiting, interventions and availability over an agreed period. Include normal people and vehicle traffic under the approved trial plan. Ask suppliers to explain failed or excluded tasks and the work required before expansion.
