Warehouses that deploy AGVs or AMRs into environments that have not been engineered for them consistently produce the same outcomes: racking damage from vehicles operating in under-width aisles, system downtime caused by floor deviations that disrupt guidance accuracy, and compliance failures that expose the business to liability before the automation ROI has been realised. The technology is not the problem, the infrastructure is. Resolving the physical environment first, and the robotics second, is what separates successful automation projects from expensive ones.
AGV vs AMR: understanding the difference
An automated guided vehicle (AGV) is a materials handling system that follows fixed paths defined by magnetic tape, wires or optical markers, requiring a controlled and predictable physical environment to operate reliably. AGV systems are deterministic: the vehicle follows the same path, at the same speed, every cycle. This predictability makes AGVs highly efficient in stable, repetitive environments but inflexible when the warehouse layout changes.
An autonomous mobile robot (AMR) is a materials handling system that uses onboard sensors, cameras and mapping algorithms to navigate dynamically, adapting its path in response to obstacles and environmental changes. AMRs do not require fixed floor markers and can reroute in real time around temporary obstructions. This flexibility comes with its own infrastructure requirements: the warehouse must still provide consistent aisle widths, predictable racking positions and floors within defined flatness tolerances for the robot’s sensors and navigation system to function accurately.
Both technologies impose specific physical requirements on the warehouse. They differ only in the nature of those requirements. An AGV demands precision in fixed geometry: exact aisle widths, marked floor paths and unobstructed travel lanes. An AMR demands consistency in the broader environment: reliable aisle clearances, stable racking positions and floors that do not exceed the sensor tolerance of the navigation system. Neither will perform to specification in a warehouse that has not been assessed and configured for its operation.
How AGVs and AMRs interact with racking and storage systems
Automation-ready racking is a steel storage system engineered to the dimensional tolerances, load ratings and bay configurations required by the specific AGV or AMR system operating within the same environment. This definition has a practical consequence: the racking specification for an automated warehouse cannot be determined independently of the robot system being deployed. Bay width, beam height, upright profile and floor anchor positions must all be reconciled with the robot’s reach envelope, load presentation requirements and travel path geometry before any fabrication begins.
AGV pallet conveyance systems present pallets to racking faces at defined positions. If racking beam heights or bay widths deviate from the specification, the AGV cannot place or retrieve loads reliably. Goods-to-person AMR systems, where a robot navigates to a pick face and presents goods to a stationary operator, require consistent shelf positions and clear aisle access at every bay. A goods-to-person system is a warehouse fulfilment model in which automated vehicles deliver goods to a fixed operator workstation rather than requiring the operator to travel through the warehouse.
Shuttle systems integrated with racking bays require specific upright profiles and beam pitch intervals matched to the shuttle’s mechanical envelope. In all automated racking environments, dimensional tolerances are tighter than in manually operated systems. A misaligned upright that a forklift operator can compensate for visually will cause a repeated positioning error for an AGV or shuttle system that follows fixed coordinates. Racking in automated environments must be installed, inspected and maintained to a higher standard than the minimum compliance threshold set by AS/NZS 4084:2023.
Infrastructure requirements for AGV and AMR deployment
Four physical requirements must be resolved before any AGV or AMR system is commissioned. Each is independent and deficiency in any one of them is sufficient to prevent deployment or degrade system performance after deployment.
Floor flatness and levelness
Floor flatness is a measurable tolerance standard that governs the maximum permitted deviation in a floor surface over a defined span, and it is critical to AGV guidance accuracy and load stability. AGV guidance systems whether magnetic, optical or laser-based are calibrated to operate within a defined floor flatness tolerance. Deviations outside that tolerance cause positioning errors that compound across a shift, resulting in missed load placements, repeated cycles and, in persistent cases, guidance system faults.
The applicable New Zealand floor flatness standard for AGV operating environments must be confirmed before any floor assessment or remediation specification is produced.
Existing warehouse floors should be assessed against the confirmed standard before an automation deployment programme begins. Floors that require remediation must be scheduled for repair as part of the fit-out programme and not as a post-commissioning correction.
Aisle width requirements
AGV fixed-path systems require aisle widths defined precisely to the vehicle’s operating envelope, with no tolerance for deviation along the travel path. The required aisle width is determined by the AGV manufacturer’s specification for the vehicle model and its maximum load width, plus any safety clearance defined in the system design. These requirements must be confirmed with the AGV vendor before the warehouse layout is designed or any racking is repositioned.
AMR systems require minimum clear aisle widths that account for the robot body width, load width and the navigation buffer required for dynamic path adjustment. AMR aisle requirements are typically less restrictive than AGV fixed-path requirements but must still be reconciled with AS/NZS 4084:2023, the current New Zealand and Australian standard for steel storage racking, which sets minimum aisle clearances based on the handling equipment type operating in each aisle. Narrowing aisles to increase racking density (a common optimisation in manually operated warehouses) can conflict directly with both AGV operating requirements and AS/NZS 4084:2023 clearance minimums.
Column and racking protection
All racking uprights at aisle ends, transfer points and AGV travel path boundaries must be fitted with rated column protectors before AGV operations commence. AGV impacts on racking uprights, even at low operating speeds, transfer concentrated forces to the upright base and floor anchor. Because AGV paths are fixed and repeat at high frequency, impact risk concentrates at the same structural points across every operating cycle. This is a damage pattern that differs from manual forklift operations, where impact locations vary with operator behaviour.
AS/NZS 4084:2023 requires that racking damage is identified and remediated promptly. In automated operating zones, damage from robot contact can accumulate incrementally and may not be immediately visible to staff conducting routine floor-level checks. Column protectors rated to the AGV’s maximum impact load, combined with a structured inspection programme, are the minimum requirement for managing racking integrity in AGV operating zones. WorkSafe New Zealand requires that identified safety hazards, including damaged racking, are remediated without delay, and that staff are informed of load limit changes resulting from structural damage.
Fire egress and emergency stop zones
AGV and AMR operating zones must maintain clear and unobstructed emergency egress paths in accordance with the New Zealand Building Code at all times, including during active robot operations. Emergency stop zones (defined areas where the robot system can be halted without blocking egress routes or creating secondary hazards) must be designated in the warehouse layout design before the automation system is commissioned. These zones cannot be defined retrospectively around an existing racking layout.
Racking reconfigurations undertaken to accommodate automation must be assessed against fire egress requirements before fabrication begins. Adding racking bays, adjusting aisle widths or repositioning shelving can alter exit path geometry in ways that are not immediately apparent from a floor plan. WorkSafe New Zealand sets obligations for the design of safe automated operating zones in environments where human workers and automated vehicles share the same building, including requirements for physical segregation, emergency stop system access and staff training on hazard identification in mixed human-robot environments.
Racking compliance in automated warehouses
AS/NZS 4084:2023, the current New Zealand and Australian standard governing steel storage racking design, installation and inspection, applies to all racking in automated environments without exception. Compliance requirements are, if anything, more critical in automated warehouses than in manually operated facilities, because damage from robot contact that goes undetected can escalate faster and reach structural significance before it becomes visible at floor level.
All racking in automated zones must carry the mandatory load signage required by AS/NZS 4084:2023, stating the maximum permissible unit load and beam load for each bay configuration. Automation does not remove the requirement for load signage — it reinforces it, because robotic pallet handling systems are programmed to present loads of a defined weight and dimensions, and any discrepancy between the programmed load and the bay’s rated capacity creates a compliance gap that must be managed through signage and load management protocols.
Inspection frequency in high-cycle automated environments should exceed the minimum intervals applicable to manually operated racking. A racking compliance inspection in an automated warehouse is a formal assessment of the storage system conducted to verify conformance with AS/NZS 4084:2023, with particular attention to impact damage patterns consistent with automated vehicle contact. Storepro’s scheduled racking inspections and AS/NZS 4084:2023 compliance assessments include automated environment inspection protocols and produce the documentation required for ongoing compliance records.
Designing a warehouse layout for automation readiness
Preparing a warehouse layout for AGV or AMR deployment requires a formal infrastructure assessment before the automation vendor arrives on site. The assessment reconciles the robot system’s operating requirements supplied by the automation vendor against the existing physical environment, and identifies constraints that will prevent deployment or degrade performance if left unresolved.
Typical constraints identified at this stage include aisles that are under-width for the robot’s operating envelope, column positions that conflict with defined travel paths, racking bay dimensions that do not match the robot’s reach or load presentation specification, floor load ratings that may be exceeded by automated pallet stacking loads, and sprinkler drop heights that restrict available bay heights. Each constraint requires a design resolution before any racking is repositioned or fabricated.
The output of a thorough assessment is a revised CAD layout and engineering specification that accommodates robot operating envelopes, charging station positions and goods-in and goods-out transfer points, with a racking specification matched to the robot’s reach and load envelope. When the automation vendor and the racking installer work from the same physical specification, the dimensional mismatches that cause commissioning delays are eliminated before they occur. Engaging a warehouse storage specialist to produce this documentation alongside or immediately after selecting the automation system, is the step most commonly omitted and most frequently responsible for delays at commissioning.
Phasing the transition from manual to automated operations
A phased transition allows AGVs or AMRs to be introduced progressively without shutting down the warehouse. Each zone commissioned for automated operation must meet all infrastructure requirements like floor flatness, aisle width, column protection and AS/NZS 4084:2023 racking compliance before the AGV or AMR system is activated in that zone. Partial compliance within a commissioned zone is not acceptable, because the robot system cannot compensate for infrastructure deficiencies and will produce errors or damage that accumulate with every operating cycle.
The phased sequence begins with the zone that will be commissioned first: Storepro reconfigures the racking, adjusts aisle widths, installs column protectors and produces the AS/NZS 4084:2023 compliance documentation for that zone before handover to the automation vendor. Manual operations continue in all adjacent zones throughout this process. Floor remediation for the first zone is sequenced ahead of racking installation, so that the surface is certified to the required flatness standard before the racking is positioned and anchored.
Subsequent zones follow the same sequence: racking reconfiguration and compliance certification first, then floor remediation if required, then handover for robot commissioning. Storepro’s project management service coordinates racking reconfiguration, trades sequencing and compliance documentation across phased fit-out programmes, ensuring that each zone is fully infrastructure-ready at the point of handover and that manual operations in adjacent zones are not disrupted during the transition.
Prepare the warehouse before the robots arrive
Deploying AGVs or AMRs into a warehouse that has not been engineered for them is the most common cause of automation underperformance. Racking damage from vehicles operating in non-compliant aisles, guidance failures caused by out-of-tolerance floors, and compliance exposures from uninspected or unsignaged racking all erode the ROI of the automation investment before it has been realised.
Storepro provides the physical infrastructure work that makes a warehouse ready for automation: racking specification, aisle geometry, floor load assessment, AS/NZS 4084:2023 compliance certification and phased project management. The robot system arrives into an environment that has been designed for it, complies with New Zealand’s racking standards and is supported by a structured inspection programme.
