Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs)

Flexible conveyor technology

Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) are increasingly replacing forklift trucks and offer an alternative to continuous conveyor technology. Unitechnik analyzes the requirements, selects suitable systems and integrates them with our UniWare warehouse management system via defined interfaces. We carefully plan transfer points to ensure seamless integration of the automated vehicles into our logistics systems.

Automated guided vehicles and autonomous robots: what do they mean?

Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) are autonomous vehicles that can transport goods and merchandise in industrial and logistical environments without human control or guidance. These systems use various technologies such as sensors, cameras, laser scanners and artificial intelligence to detect their surroundings and navigate safely, making driverless transport versatile. Speed is important with driverless transport systems: they are usually designed for moderate speeds to ensure safety within production and warehouse environments.

Abbreviations

AGV: Automated guided vehicle
AMR: Autonomous mobile robot
FTF: Automated guided vehicle (also AGV)
AGV: Automated guided vehicle (also FTF)
Vehicles: AMR or FTF, or AGV

What is an automated guided vehicle system (AGV)?

  • Equipment: AGVs consist of automated guided vehicles (AGVs) with sensors, cameras or laser navigation systems
  • Central control system: Coordinates communication, order placement, route planning and monitoring of the AGVs
  • Navigation: AGVs navigate on predefined physical or virtual paths such as magnetic tapes, induction loops or reflector triangulation
  • Reaction to obstacles: AGVs stop and wait until obstacles are removed if safety sensors detect them
  • Path adherence: vehicles cannot leave the specified path and follow it strictly

What is an autonomous mobile robot (AMR)?

  • Similarity to AGVs: AMRs look similar to AGVs on the outside, but differ in terms of navigation
  • Natural navigation: AMRs can redefine routes and avoid obstacles without the need for fixed paths
  • Self-navigation: The robot maps its environment and navigates without fixed hardware by using laser scanners, cameras or lidar systems
  • Communication: AMRs communicate either via a central control system or directly with each other
  • Swarm intelligence: Several AMRs work together to achieve a common goal through collective intelligence

Areas of application for AGVs and AMRs

Areas of application for AMR

AMRs are suitable for applications with multiple and variable destinations, e.g:

  • Supply of workstations with material
  • Autonomous mobile picking robots
  • In hospitals, for example disinfection robots
  • Warehouse applications, especially in e-commerce and parcel services
  • Autonomous floor cleaners

Areas of application for AGVs

AGVs have their strengths where defined transport routes need to be operated at high frequency and as predictably as possible.

In summary, it can be said that AGVs are often used in intralogistics environments to perform specific transportation tasks on predefined routes. AMRs, on the other hand, are more versatile and flexible and can navigate and operate autonomously in different industries and environments.

FAQs on automated guided vehicles and autonomous mobile robots

Yes, they are!
AMR offer the possibility to add or change routes easily and effortlessly. Usually, the environment is mapped and a route is created - that's all. Changing an AGV route requires a little more work and in many cases the support of the provider.

Flexibility can come at the expense of performance. This is because it does not always make sense to look for an alternative route in the event of an obstacle, e.g. a person in the path of travel. In addition, an AGV is more predictable for people, as the vehicles always behave in the same way.

Not at all. Both AMR and AGVs are safe. Both use the same safety equipment to avoid collisions and ensure the required level of safety.

The fleet manager is a central control system that manages the vehicles. It is responsible for planning, coordination and monitoring. The vehicles communicate with the central system and receive instructions.

With swarm intelligence, the vehicles work together decentrally and autonomously. Each vehicle makes its own decisions, communicates with other vehicles and coordinates their movements. This allows them to react flexibly to changes and find optimal routes.

AGVs usually have a fleet manager; AMR systems have both.

There are several important aspects when introducing automated guided vehicles (AGVs) or autonomous mobile robots (AMRs):

  1. System selection
    The system must be technically suitable for the specific tasks, as companies have different requirements.
  2. Technical equipment & safety
    Reliable sensors and emergency measures are crucial to minimize failures.
  3. Infrastructure
    The environment must offer sufficient space and comply with ground tolerances.
  4. Energy management
    Charging and parking stations must be planned and charging times taken into account in the power calculation.
  5. Transfer points
    The design of sources and sinks requires expert knowledge.
  6. Employee training
    Appropriate training and clear communication promote acceptance of the system.
  7. Scalability
    The system should be expandable and able to react flexibly to future requirements.

CONCLUSIONS:

  • AMR and FTS offer great potential, but are not ideal for every application
  • Every project requires a detailed analysis
  • The decision between AMR and AGVs must make technical and economic sense
  • Increased efficiency and flexibility depend on the right choice of system
