AGV vs AMR: Understanding the Difference
The terms AGV and AMR are often used interchangeably, but they represent fundamentally different approaches to mobile automation:
Automated Guided Vehicles (AGV)
AGVs follow predetermined paths using physical guidance infrastructure. Think of them as automated trains — reliable, predictable, and efficient along fixed routes. They excel in stable environments where routes rarely change and throughput is the primary concern. AGVs have been in use since the 1950s and represent a mature, proven technology.
Autonomous Mobile Robots (AMR)
AMRs perceive their environment through sensors and make real-time navigation decisions. They build maps of their surroundings using SLAM technology and navigate around obstacles dynamically. AMRs can be deployed in days (vs weeks for AGVs), route changes require only software updates (vs physical infrastructure modifications), and they coexist safely with human workers without dedicated lanes.
| Factor | AGV | AMR |
|---|---|---|
| Navigation | Fixed path (tape/wire/reflector) | Dynamic (SLAM/LiDAR) |
| Deployment time | 2-8 weeks | Days to 2 weeks |
| Route flexibility | Low (physical changes needed) | High (software-only changes) |
| Obstacle handling | Stop and wait | Navigate around |
| Cost per vehicle | $30,000-$120,000 | $15,000-$80,000 |
| Infrastructure cost | $10,000-$50,000 | Minimal ($5,000-$15,000) |
| Best for | High-volume, fixed routes | Dynamic, changing environments |
Navigation Technologies Compared
The choice of navigation technology is the most important technical decision when selecting an AGV/AMR:
- Magnetic tape guidance: Lowest cost, easiest to implement. The AGV follows a magnetic strip adhered to the floor. Accuracy: +/- 10mm. Best for: simple, fixed routes in controlled environments. Limitation: tape wears and requires replacement every 1-2 years in high-traffic areas
- Magnetic spot/QR code navigation: Floor-embedded magnetic spots or printed QR codes at grid intersections. The vehicle navigates between spots using odometry. More flexible than tape — route changes require moving/adding spots rather than re-laying tape. Popular with Chinese AMR manufacturers (Geek+ standard)
- Laser reflector (LGV): Vehicle-mounted laser scanner triangulates position using reflectors on walls or pillars. No floor modifications needed. Accuracy: +/- 5mm. Higher cost but cleaner installation. Standard for European-style AGVs
- Natural feature SLAM: LiDAR-based mapping uses existing structural features (walls, columns, racking) for navigation. Most flexible — no infrastructure required. Accuracy: +/- 10-20mm. The standard for modern AMRs. Requires stable environment structure
- Vision navigation: Camera-based systems using visual landmarks or ceiling features. Lower cost than LiDAR SLAM. Used by some AMR manufacturers for specific applications
Payload & Vehicle Types
AGVs and AMRs are built across a wide payload spectrum:

Implementation Best Practices
- Start with a pilot area (one zone or one shift) before scaling fleet-wide
- Involve maintenance team early — they will be responsible for daily operations
- Ensure WiFi coverage meets AGV/AMR requirements (typically dedicated SSID with <50ms latency)
- Plan for traffic management — intersections, right-of-way rules, human-robot interaction zones
- Integrate with WMS/ERP for automated task dispatch
- Establish KPIs: utilization rate, on-time delivery, battery health, incident tracking

Frequently Asked Questions
What is the difference between AGV and AMR?
AGV (Automated Guided Vehicle) follows a fixed path defined by physical infrastructure — magnetic tape on the floor, embedded wires, or reflector-based laser guidance. AGVs are reliable and predictable but inflexible: changing routes requires physical infrastructure modifications. AMR (Autonomous Mobile Robot) navigates dynamically using onboard sensors (LiDAR, cameras, ultrasonic) and SLAM (Simultaneous Localization and Mapping) algorithms. AMRs build a map of their environment and navigate around obstacles in real-time. AMRs are more flexible and easier to deploy but cost 20-50% more than equivalent AGVs. Choose AGV for: stable, high-volume, repetitive routes in controlled environments. Choose AMR for: dynamic environments with frequent layout changes, mixed human-robot spaces, and operations requiring flexibility.
What navigation technologies are available for AGVs?
Six main navigation technologies: (1) Magnetic tape/strip: Cheapest and simplest. AGV follows a magnetic tape line on the floor. Easy to install and modify. Accuracy: +/- 10mm. Cost: lowest. (2) Magnetic spot/grid: Floor-embedded magnetic points at intersections, with dead reckoning between points. More flexible routing than tape. (3) Laser/reflector: AGV triangulates position using laser scanning of reflectors mounted on walls/pillars. Accuracy: +/- 5mm. No floor infrastructure needed. (4) Natural feature navigation (SLAM): Uses LiDAR to map the environment and navigate using existing structural features. Most flexible but highest cost. (5) Vision-guided: Uses cameras and visual markers or natural features for navigation. (6) Inertial/GPS: For outdoor applications. Each technology has tradeoffs between cost, accuracy, flexibility, and environmental requirements.
What payload capacities are available for AGVs?
AGVs are manufactured across a wide payload range: Light-duty (up to 300 kg): Mobile robots for bin/tote transport, typically AMR-style. Used for goods-to-person picking operations. Medium-duty (300-1,500 kg): The most common range, handling standard pallets and roll cages. Suitable for most warehouse and manufacturing transport tasks. Heavy-duty (1,500-10,000 kg): For moving full pallets, coils, heavy assemblies, and materials. Common in automotive, steel, and heavy manufacturing. Ultra-heavy (10,000-100,000+ kg): Specialized vehicles for moving shipping containers, heavy machinery, aircraft components, and large structural assemblies. Chinese manufacturers produce competitive AGVs across all payload ranges, with particularly strong offerings in the medium and heavy-duty categories.
How many AGVs do I need for my warehouse?
Fleet sizing depends on four factors: (1) Transport volume: Number of loads to move per hour during peak periods. (2) Route distance: Average distance between pickup and drop-off points. (3) Load/unload time: Time at each station including positioning, loading, and unloading. (4) Battery/charging strategy: Available operational hours per vehicle per day. A rough formula: Fleet Size = (Moves/Hour x Average Cycle Time in Minutes) / 60. Example: 30 moves/hour, 8-minute average cycle = (30 x 8) / 60 = 4 AGVs. Add 20-30% buffer for charging, maintenance, and traffic congestion. Most AGV suppliers provide simulation software that models your specific layout and throughput requirements to determine optimal fleet size. Contact IntralogDB for supplier recommendations.
