Key differences at a glance
- Navigation: AMRs build and use a dynamic map of the environment; AGVs follow fixed paths (magnetic tape, wire, laser reflectors, or QR codes)
- Obstacle response: AMRs reroute autonomously; AGVs stop and wait (or alarm)
- Infrastructure: AMRs need no floor modification; most AGVs require floor prep
- Cost: AMRs cost more upfront ($40,000–$150,000+) but deploy faster; AGVs cost less ($20,000–$80,000) but require infrastructure investment
- Best fit: AMRs for dynamic, mixed-use facilities; AGVs for dedicated, predictable, high-throughput lanes
AMR and AGV defined
An Autonomous Mobile Robot (AMR) is a wheeled vehicle that navigates by building a real-time map of its environment using lidar, cameras, or both (a technique called SLAM — Simultaneous Localisation and Mapping). It can plan paths, reroute around obstacles, and operate in facilities shared with people and vehicles without any floor infrastructure.
An Automated Guided Vehicle (AGV) is a wheeled vehicle that follows a pre-defined path defined by a physical or electronic guide: magnetic tape embedded in the floor, inductive wire, laser reflectors on walls, QR codes on the ceiling, or (in newer systems) natural-feature laser scanning on a fixed-layout map. AGVs do not reroute — when blocked, they stop.
The distinction is eroding: some newer AGVs use lidar navigation that resembles AMR technology, and some AMR vendors use the terms interchangeably. When evaluating vendors, ask specifically: can the vehicle dynamically reroute around a blocked path in real time? If yes, it behaves as an AMR regardless of the marketing label.

| Cost item | Estimate |
|---|---|
| AMR unit purchase | $55,000–$120,000 |

| Cost item | Estimate |
|---|---|
| AGV unit purchase | $25,000–$70,000 |
| Floor infrastructure (tape/wire/reflectors) | $5,000–$30,000 |
| Control system and scheduling software | $3,000–$15,000 |

The AGV cost advantage narrows significantly when floor infrastructure costs are included, and disappears entirely if layouts change frequently (requiring floor modification). For multi-unit fleets, software licensing costs for AMRs become proportionally smaller per unit.
Choose-if framework
Choose an AMR if:
- Your facility has mixed pedestrian and vehicle traffic
- Layout changes frequently (new production cells, seasonal rearrangement)
- You need rapid deployment (weeks, not months)
- Routes are not fixed — the robot serves multiple pickup/dropoff points
- You need dynamic tasking from an MES or WMS
- You are starting with 1–3 units and scaling gradually
Choose an AGV if:
- You have a dedicated, fixed-route material flow that rarely changes
- High throughput with heavy payloads (1,000+ kg) is required
- You have an existing AGV infrastructure to expand
- The environment is predictable with minimal human traffic
- You have the floor time for tape/wire installation without production disruption
- Cost per unit is the primary constraint and routes are well-defined

Frequently asked questions
Can AMRs and AGVs operate in the same facility?
Yes, though managing two separate fleets adds operational complexity. Larger facilities sometimes use AGVs for fixed high-throughput routes (e.g., main production supply lanes) and AMRs for dynamic distribution tasks (e.g., kitting, WIP delivery to cells). The two fleets typically use separate traffic management systems and require clearly defined zones to prevent conflicts. Most sites with both technologies operate them in spatially separated areas rather than fully integrated traffic management.
What is the difference between SLAM and natural feature navigation?
SLAM (Simultaneous Localisation and Mapping) builds a map in real time and continuously updates the robot's position within it — enabling truly dynamic navigation and obstacle avoidance. Natural feature navigation (used in some newer AGVs) also uses lidar, but matches against a pre-surveyed fixed map and follows pre-programmed routes rather than planning paths dynamically. The practical difference: true SLAM-based AMRs reroute around blocked paths; natural-feature AGVs stop and wait.
How do AMRs handle low light or crowded environments?
Lidar-based AMRs do not rely on visible light — they use laser pulse return times and are not affected by darkness or glare. In crowded environments, AMRs slow to their "reduced speed" zone (typically 0.5–0.8 m/s) when people or obstacles are detected within the safety zone, as required by ISO 3691-4. Very crowded environments with constant obstacles can significantly reduce AMR throughput — fleet sizing must account for this. Camera-based navigation (visual SLAM) is affected by lighting changes; lidar-based navigation is generally more robust.
What ROI can I expect from an AMR deployment?
AMR ROI depends almost entirely on how much material-handling labour is replaced. A single AMR replacing a forklift driver or cart pusher who earns $45,000–$60,000/year (fully loaded) pays back a $70,000 AMR in 12–18 months on one shift. Two-shift operation halves the payback. AMRs that move small quantities infrequently (replacing tasks that take 30 minutes per shift) have weak ROI. Map the current-state material flows in hours/person-shift before sizing the fleet and calculating ROI. Use the ROI calculator to model your specific numbers.
