AGV Navigation
Tape, wire, magnetic spots, reflectors, lasers, or defined guidance paths create repeatable routes.
AGV vs AMR
AGVs and AMRs move materials with different navigation strategies.
Automatic guided vehicles generally follow defined routes, while autonomous mobile robots use onboard sensing and mapping to navigate more flexibly around changing environments.
Overview
Design the system around the operating decision.
AGVs and AMRs can transport pallets, carts, totes, components, tools, waste, and work in process. The best choice depends on route stability, load, traffic, floor conditions, interaction with people, integration, charging, fleet size, and the cost of changing the layout.
Core Concepts
The technology, integration, safety, and support factors to review.
These categories provide a consistent framework for system design, selection, validation, operation, and long-term support.
AMR Navigation
Onboard mapping, localization, lidar, cameras, and sensors allow dynamic path planning.
Load Handling
Forks, conveyors, lifts, tuggers, carts, racks, and custom tooling transfer different unit loads.
Infrastructure
Floor markings, reflectors, charging, doors, Wi-Fi, traffic controls, and pickup stations support operation.
Safety
Scanners, bumpers, speed zones, warning devices, safe stopping, and risk assessment protect people and equipment.
Fleet Management
Software assigns missions, manages traffic, priorities, congestion, charging, and vehicle status.
System Integration
Interfaces coordinate production systems, conveyors, machines, warehouse software, elevators, and doors.
Lifecycle Cost
Vehicles, infrastructure, software, batteries, support, maintenance, spares, and layout changes affect total cost.
When AGVs are a strong fit
AGVs work well in stable facilities with repetitive routes, predictable pickup points, controlled intersections, and long operating periods. Guided paths can simplify behavior and make traffic highly repeatable.
They may also be preferred for heavy loads, specialized vehicles, or environments where a clearly defined route is operationally desirable.
When AMRs provide more flexibility
AMRs can reroute around obstacles and adapt more easily when production layouts, destinations, or priorities change. They are useful where facilities need scalable point-to-point movement without installing a fixed path for every route.
Flexibility still depends on floor quality, map accuracy, network coverage, safe aisle space, traffic rules, and well-designed pickup and drop-off stations.
Safety and traffic planning
Mobile robots share space with pedestrians, forklifts, carts, doors, blind corners, and production equipment. Risk assessment should address speed, load stability, stopping distance, intersections, charging, manual recovery, and foreseeable misuse.
A flexible navigation system does not eliminate the need for traffic rules. Congestion, blocked stations, narrow aisles, and uncontrolled forklift activity can reduce throughput and create risk.
Calculating system capacity
Vehicle count should be based on travel distance, speed, load and unload time, wait time, congestion, charging, availability, and peak mission demand. Average demand alone may understate the fleet required during shift changes or production surges.
Simulation or pilot testing can help evaluate routes, station design, traffic, battery strategy, and expected mission completion time.
Implementation Checklist
What engineering and operations teams should define.
Use these areas to translate the use case into technical requirements, acceptance criteria, documentation, controls, and lifecycle support.
Material Flow Map
Document origins, destinations, routes, distances, traffic, mission frequency, and peak demand.
Load Definition
Specify weight, dimensions, stability, orientation, pallet or cart type, and transfer method.
Navigation Review
Compare fixed guidance, natural-feature navigation, mapping, obstacle response, and layout change.
Safety Plan
Assess pedestrians, forklifts, intersections, doors, blind spots, speed zones, and manual recovery.
Integration Scope
Define fleet software, WMS, MES, ERP, PLCs, conveyors, machines, doors, and elevators.
Lifecycle Support
Plan batteries, chargers, spares, service, software licensing, cybersecurity, training, and expansion.

Frequently Asked Questions
AGV vs AMR FAQ
What is the main difference between an AGV and an AMR?
AGVs generally follow defined guidance paths, while AMRs use onboard sensing and mapping to navigate and reroute more flexibly.
Are AMRs always better than AGVs?
No. AGVs can be a better fit for stable routes, specialized heavy loads, and facilities that value highly predictable guided movement.
How many mobile robots does a facility need?
Fleet size depends on travel distance, mission rate, load time, traffic, charging, availability, and peak demand rather than average demand alone.
