Understanding the Difference
AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots) both transport goods within a warehouse, but their underlying technologies create distinct capabilities and limitations. Understanding these differences helps you choose the right solution for your operations.
AGV: Fixed Path Navigation
AGVs follow predetermined paths using various guidance technologies:
- Tape or wire: Embedded in the floor
- Paint or magnets: Surface-mounted markers
- Laser guidance: Reflectors mounted on walls and pillars
AGVs are reliable and proven technology, suitable for high-volume, repetitive transport tasks in fixed routes. They excel in environments where the transport path rarely changes and throughput requirements are predictable.
AMR: Dynamic Path Navigation
AMRs use onboard sensors and mapping software to navigate dynamically:
- LIDAR: 360-degree obstacle detection
- Camera-based SLAM: Simultaneous localization and mapping
- AI path planning: Real-time route optimization
AMRs adapt to changing layouts, avoid obstacles autonomously, and can be redeployed quickly for different tasks. They suit environments where flexibility matters more than absolute throughput.
Head-to-Head Comparison
| Factor | AGV | AMR |
|---|
| Navigation | Fixed path | Dynamic/free |
| Deployment | Infrastructure required | Map and go |
| Flexibility | Low | High |
| Throughput | Very high | Moderate |
| Best For | Repetitive, high-volume | Flexible, evolving needs |
| Obstacle Avoidance | Basic/stop | Advanced/avoid |
| Cost | Higher infrastructure | Lower deployment |
For ASRS Integration
When integrated with ASRS systems, both AGVs and AMRs serve as the transport layer between storage and workstations. The choice depends on your facility layout and operational patterns:
- Choose AGV: High-volume production lines, stable layouts, maximum throughput, cleanroom or GMP environments
- Choose AMR: E-commerce fulfillment, mixed SKUs, frequent layout changes, collaborative picking zones
MB Intelligence Recommendation
For most warehouse automation projects, we recommend AGV-based transport when throughput demands are high and the layout is stable. Our four-way shuttle ASRS integrates seamlessly with AGV systems, providing a complete automated storage and transport solution. Contact us to evaluate which option fits your specific requirements.
