Optimize Navigation for Automated Guided Vehicles (AGVs) – Pros & Cons

Automated Guided Vehicles
Automated Guided Vehicles

Automated Guided Vehicles (AGVs) are driverless transport vehicles powered by rechargeable batteries and equipped with various guidance systems such as electromagnetic, optical, or vision sensors. AGVs are extensively used for factory transportation, warehouse logistics, medical equipment transport, and automated parking.

Navigation Methods of Automated Guided Vehicles

Magnetic Strip Navigation:

  • Pros: Flexible, easy path modification.
  • Cons: Susceptible to interference from metal, can be easily damaged, requires a controlled environment.

QR Code Navigation:

  • Pros: Simple deployment, low maintenance, cost-effective, no environmental changes needed.
  • Cons: Requires regular maintenance, certain environmental conditions needed.

Laser Navigation:

  • Pros: High flexibility, uses SLAM algorithms for accurate mapping, no additional equipment needed.
  • Cons: Expensive, high environmental requirements (lighting, visibility).

Vision Navigation:

  • Pros: Uses SLAM with onboard cameras for flexible navigation, more cost-effective than laser.
  • Cons: High environmental requirements, technology is less mature.

Advantages and Disadvantages

  • Magnetic Strip Navigation:
    • Advantages: Precise and cost-effective.
    • Disadvantages: Requires additional equipment, susceptible to environmental factors.
  • QR Code Navigation:
    • Advantages: Precise, flexible, and low-cost.
    • Disadvantages: Needs regular maintenance, specific environmental conditions.
  • Laser Navigation:
    • Advantages: Accurate and adaptable.
    • Disadvantages: Expensive, requires specific environmental conditions.
  • Vision Navigation:
    • Advantages: Flexible and cost-effective compared to laser.
    • Disadvantages: High environmental requirements, technology is still developing.


While laser navigation has become the mainstream solution for Automated Guided Vehicles due to its precision and flexibility, vision navigation is gaining attention for its potential. Each navigation method has its own set of advantages and disadvantages, making it essential to choose the right one based on specific operational requirements.
