Warehouse robotics is best compared by the material-handling job, not by a broad product label. A mobile robot moving a pallet, a robotic arm handling cartons, and an automated storage system face different loads, layouts, people, and integration needs. Start with one repetitive or difficult task, describe its normal and exception cases, and ask suppliers to demonstrate the exact operating conditions.
Compare equipment by task
Mobile transport
Automated guided vehicles and autonomous mobile robots can be considered for moving pallets, carts, or other loads between receiving, storage, production, and picking areas. Compare payload and load transfer as well as route planning, intersections, docking, charging, and recovery from an obstruction. The labels do not by themselves specify navigation method or site fit. ISO 3691-4:2023 identifies AGVs and AMRs among examples of driverless industrial trucks within its stated scope.
Fixed handling and palletizing
Robotic arms and other fixed automation may handle a defined pick, place, sort, or palletizing task. Evaluate the item range, packaging variation, presentation, grip, reach, cycle sequence, guarding, and changeover process. If the work shifts between products or packaging, include those transitions in the trial rather than demonstrating only a repeatable sample.
Storage, sortation, and specialized equipment
Automated storage and retrieval, conveyors, sortation, drones, yard equipment, and delivery robots have distinct operating zones and safety considerations. Name the equipment and the task precisely; requirements for a driverless industrial truck should not be assumed to cover every automated machine.
Check site and system fit
Before selecting equipment, map aisle widths, floor condition, thresholds, pedestrian routes, crossings, handoff stations, charging, and maintenance access. Plan what happens if a route is blocked, a load is missing, communication drops, or the equipment needs service. OSHA's warehousing safety guidance covers hazards such as powered-truck and pedestrian interactions; automation does not replace site risk controls or worker training.
Trace the work from release to completion: which warehouse or control system assigns the task, how the robot accepts it, how completion is reported, and how inventory records change. Demonstrate a fault and the manual fallback. NIST's robotics measurement program emphasizes expressing performance in the context of intended requirements and environments. Apply that idea to your own load, layout, traffic, and operating schedule instead of comparing abstract speed claims.
Plan a buyer trial
- Define the task, load range, routes, variation, and operating hours.
- Use the intended floor, aisle, handoff, and human interaction conditions.
- Test normal work plus blocked paths, item mismatch, lost communication, and recovery.
- Agree in advance on throughput, availability, fault, safety, and labor measures.
- Include equipment, installation, facility changes, charging, software, training, maintenance, parts, and support in the proposal.
ISO 3691-4:2023 concerns safety requirements and verification for driverless industrial trucks and their systems; check the equipment's exact scope and current applicable standards with qualified safety personnel. A test on one site helps establish local fit, not a result for every warehouse.
Questions buyers ask
Are AGVs and AMRs interchangeable?
Not necessarily. Product designs and navigation differ, so confirm how the proposed unit handles routes, loads, traffic, and exceptions in your environment.
Does a robot need WMS integration?
The design varies, but the buyer should know how work is assigned, completed, and reconciled. Ask for a complete transaction demonstration and a manual process when the integration is unavailable.
Does a safety standard certify the installation?
No. A standard has a defined scope, and a site still needs appropriate equipment selection, risk review, work procedures, and training.
