| 1. Unit-Load Transport AGV | Moving standardized loads between production, storage, and shipping areas | Laser, natural-feature, QR-code, or hybrid navigation | 500–2,000 kg | 0.8–1.5 m/s | Top-mounted conveyor, rollers, or deck | Automotive components, electronics, appliances, and general manufacturing | Load dimensions, transfer height, docking accuracy, route density, and interface compatibility | Requires consistent load presentation and clearly defined transfer points |
| 2. Tugger Train AGV | High-volume line-side replenishment using multiple carts | Magnetic tape, laser, natural-feature, or mapped navigation | 1,000–5,000 kg total train capacity | 0.6–1.2 m/s | Towed carts, stillages, or roll cages | Automotive assembly, industrial equipment, and large-scale production | Turning radius, train length, aisle width, coupling method, and pedestrian interaction | Needs wide, predictable routes and sufficient maneuvering space |
| 3. Automated Guided Forklift | Automating pallet transport, staging, and put-away operations | Laser, reflector, QR-code, or natural-feature navigation | 1,000–3,000 kg | 0.8–1.5 m/s | Fork pockets, floor-level pallets, and rack locations | Warehouses, distribution centers, cold-chain facilities, and factories | Pallet quality, rack tolerance, floor condition, lift height, and safety zoning | Damaged pallets, uneven floors, or variable rack conditions can reduce reliability |
| 4. Pallet Stacker AGV | Automated pallet stacking and retrieval at moderate storage heights | Laser, QR-code, or natural-feature navigation | 500–1,500 kg | 0.6–1.2 m/s | Forks with lift mast, usually for floor or low-level storage | Small warehouses, manufacturing supermarkets, and buffer storage | Required lift height, pallet stability, aisle width, and floor flatness | Less suitable for very high-bay storage or highly irregular pallet loads |
| 5. Conveyor-Top AGV | Flexible point-to-point movement with automated load transfer | Laser, camera, QR-code, or hybrid navigation | 300–1,500 kg | 0.8–1.5 m/s | Roller, belt, chain, or lift-and-transfer conveyor | Packaging, sorting, assembly, and goods-to-line delivery | Conveyor height, transfer timing, load center, PLC communication, and throughput | Requires precise mechanical and software integration at every handoff |
| 6. Low-Profile Cart Carrier | Moving wheeled carts or racks under space-constrained conditions | Laser, visual, QR-code, or natural-feature navigation | 300–1,000 kg | 0.6–1.2 m/s | Under-riding, towing, or lifting a dedicated cart | E-commerce fulfillment, apparel, electronics, and kitting operations | Vehicle clearance, cart geometry, load stability, fleet traffic, and charging strategy | Performance depends on standardized carts and adequate clearance beneath them |
| 7. Cleanroom AGV | Contamination-controlled material transport in regulated production areas | Laser, magnetic, QR-code, or mapped navigation | 100–1,000 kg | 0.3–1.0 m/s | Enclosed deck, cassette carrier, or customized transfer module | Semiconductor, pharmaceutical, medical-device, and laboratory production | Cleanroom class, particle generation, materials, sealing, maintenance, and validation records | Higher purchase, validation, and maintenance requirements than standard AGVs |
| 8. Cold-Storage AGV | Reliable pallet or container transport in chilled and frozen environments | Laser, QR-code, or natural-feature navigation | 500–2,000 kg | 0.5–1.2 m/s | Forks, rollers, or enclosed load platforms | Food distribution, frozen goods, pharmaceuticals, and temperature-controlled logistics | Operating temperature, condensation control, battery performance, floor traction, and corrosion resistance | Battery capacity and sensor reliability may decline at very low temperatures |
| 9. Outdoor-Capable AGV | Connecting buildings, yards, docks, and outdoor staging areas | GNSS, LiDAR, camera, radar, or multi-sensor navigation | 1,000–10,000 kg | 0.5–1.5 m/s | Trailers, pallets, bins, or heavy-duty platforms | Ports, construction materials, steel, paper, timber, and inter-building logistics | Weather protection, terrain, drainage, visibility, communications coverage, and emergency procedures | Rain, dust, snow, uneven surfaces, and poor positioning signals increase complexity |
| 10. Heavy-Duty Platform AGV | Transporting oversized or very heavy materials through industrial facilities | Laser, inertial, magnetic, or hybrid navigation | 5,000–50,000+ kg | 0.2–0.8 m/s | Flat platform, hydraulic lift, turntable, or custom fixture | Steel fabrication, shipbuilding, aerospace, heavy machinery, and large-component assembly | Floor load rating, wheel configuration, stopping distance, turning envelope, and structural safety | High infrastructure, engineering, and commissioning costs; usually requires site-specific design |
