In every MRO hangar, there is a bottleneck that no inspection tool, no engine test cell, and no technician can fix. It is the time spent walking. Studies across aviation maintenance facilities show that technicians spend 38 to 42 percent of their shift simply retrieving parts, tools, and materials — not performing maintenance. A part that takes 35 to 60 minutes to locate and deliver is not a supply chain problem; it is a hangar logistics problem. And until recently, the only solution was more people, more walkie-talkies, and more stockrooms. Automated Guided Vehicles and Autonomous Mobile Robots change this entirely. Instead of a technician walking 15,000 steps per shift chasing parts, a robot fleet delivers those parts directly to the aircraft bay. Instead of tooling lost for hours across a 50,000-square-meter hangar, every tool is tracked and delivered by a bot with digital chain-of-custody. Instead of stockroom clerks kitting parts manually, the logistics system pre-builds kits and delivers them before the task even starts. The technology exists today. The ROI is measurable in months. The only question is whether your hangar will automate before your competitors do.
The Hidden Cost of Walking
Why Technicians Spend Nearly Half Their Shift Not Doing Maintenance
The most expensive resource in any MRO hangar is the certified technician. Yet the typical maintenance facility structures its layout and logistics in a way that guarantees that technician will spend 38 to 42 percent of every shift walking between the stockroom, the tool crib, the staging area, and the aircraft. This is not a productivity problem caused by lazy workers. It is a structural problem caused by hangars designed around aircraft, not around parts flow. The data below compares manual hangar logistics against AGV/AMR-automated facilities, based on measured results from production MRO environments.
AGV vs. AMR — Which Bot Belongs in Your Hangar
Navigation, Flexibility, Cost, and Deployment Compared for MRO Environments
The terms AGV and AMR are often used interchangeably, but they describe fundamentally different automation technologies with different strengths in the hangar environment. AGVs follow fixed paths using magnetic tape, wire, or reflective markers. AMRs navigate dynamically using laser SLAM, 3D vision, and onboard intelligence. The right choice depends on whether your hangar layout changes frequently, how much traffic you have, and whether you need the flexibility to reroute bots on the fly.
| Capability | AGV (Automated Guided Vehicle) | AMR (Autonomous Mobile Robot) | Winner for MRO |
|---|---|---|---|
| Navigation | Fixed path — magnetic tape, wire, or reflective markers | Dynamic — laser SLAM, 3D vision, onboard map building | AMR |
| Obstacle handling | Stops on obstacle — requires human clearance | Routes around obstacle in real time | AMR |
| Layout change impact | Requires tape/ marker relocation and path reprogramming | Auto-updates map; no infrastructure changes needed | AMR |
| Deployment time (first unit) | 2-6 weeks for tape installation and path testing | 12-48 hours for auto-mapping and go live | AMR |
| Per-unit cost | $30K-$80K per vehicle (lower hardware cost) | $50K-$150K per robot (higher onboard compute) | AGV |
| Fleet scalability | Linear — each AGV requires fixed-path coordination | Non-linear — swarm coordination auto-deconflicts | AMR |
| Best MRO use case | Stable hangars, repetitive routes, predictable traffic | Dynamic hangars, mixed traffic, frequent layout changes | AMR typically |

How Bots Move Through Your Hangar
Zone-to-Zone Material Flow in an Automated MRO Facility
An automated hangar is organized into functional zones, each with specific robot types and workflows. The diagram below shows how parts, tools, and materials flow through a typical MRO facility when AGV/AMR logistics is managed by iFactory's platform.
What Automation Saves — Measured Results from MRO Deployments
Before and After Metrics from Hangars That Made the Switch
For a typical widebody MRO hangar with 80 technicians across two shifts, the transition from manual logistics to AGV/AMR automation delivers $2.8 million to $4.5 million in annual labor productivity gains alone. When tool loss reduction, inventory accuracy improvements, and reduced AOG parts expediting are included, total annual benefits reach $3.5 million to $6 million per facility. Against iFactory's Logistics & Parts Tracking Module deployment — including fleet integration, zone mapping, and CMMS connection — documented payback periods range from 6 to 14 months, with higher-throughput hangars recovering investment within the first two quarters.

Frequently Asked Questions
What is the difference between an AGV and an AMR?
An AGV (Automated Guided Vehicle) follows fixed physical paths — magnetic tape, wire, or reflective markers — and stops if an obstacle is in its way, requiring human intervention to clear the path. An AMR (Autonomous Mobile Robot) uses laser SLAM, 3D vision, and onboard intelligence to build a map of its environment, navigate dynamically around obstacles, and choose optimal routes in real time. AMRs deploy faster and handle layout changes easily, but cost more per unit. AGVs are lower-cost and reliable for stable, predictable routes. Most MRO hangars benefit from a mixed fleet: AMRs for dynamic areas near active aircraft bays, AGVs for repetitive long-haul routes between warehouses and staging zones.
How much does an AGV/AMR fleet cost for an MRO hangar?
A typical MRO hangar fleet ranges from 5 to 20 bots depending on facility size, shift structure, and task volume. AGV costs range from $30,000 to $80,000 per unit. AMR costs range from $50,000 to $150,000 per unit. A mixed fleet of 10 bots with iFactory's Logistics Module integration, zone mapping, and CMMS connection typically costs $600,000 to $1.2 million fully deployed. Against documented labor savings of $2.8 million to $4.5 million annually for an 80-technician facility, payback is achieved within 6 to 14 months — with most facilities seeing positive ROI within the first two quarters.
Can AGVs and AMRs operate safely around aircraft and personnel?
Yes. Modern AGVs and AMRs are designed with multiple safety layers including laser scanners, 3D cameras, ultrasonic sensors, and emergency stop buttons. They operate at speeds of 1.0 to 1.5 m/s in aircraft zones — equivalent to a slow walking pace. Robots automatically slow down and stop when personnel enter their safety field, and resume once the path is clear. ISO 3691-4 provides the safety standard framework for industrial AGVs and AMRs, and all major manufacturers certify their vehicles to this standard. iFactory's platform also supports geofenced speed zones — bots move faster in warehouse aisles and slower near aircraft.
How long does it take to deploy AGV/AMR logistics in a hangar?
AMR fleets can be operational in 2 to 4 weeks from delivery. The first bot typically maps the hangar in 12 to 48 hours. Additional bots join the map in under 20 minutes each. AGV fleets require 4 to 8 weeks due to tape or marker installation across the facility. iFactory's platform setup — including CMMS integration, inventory mapping, and zone configuration — completes in 1 to 2 weeks and runs in parallel with the bot deployment. The critical path is usually the hangar layout finalization, not the technology installation.
What happens when the hangar layout changes?
With AMRs, layout changes require zero infrastructure modification. The robot updates its map automatically as it navigates the new layout. Rerouting is handled through iFactory's platform — operations managers drag and drop new zone boundaries and delivery points in minutes. With AGVs, layout changes require physically relocating tape or markers and reprogramming paths — typically 1 to 3 days of work per route change. This is why most MRO facilities with evolving hangar configurations choose AMRs for the primary fleet and reserve AGVs for fixed, stable routes like warehouse-to-staging transfers.
How does iFactory integrate with existing AGV/AMR brands?
iFactory's Logistics & Parts Tracking Module connects to all major AGV and AMR brands via REST API or MQTT, including MiR, KUKA, Omron, AGILOX, Geek+, Locus Robotics, and all standard TCP/UDP-compatible fleet managers. The platform translates CMMS work order material requirements into bot dispatch commands regardless of the robot brand. If your fleet manager exposes a standard API, iFactory can integrate within days. For legacy AGVs without API capability, iFactory supports integration via I/O signal interfaces or barcode-scanner trigger points at pickup and delivery stations.
