Manufacturing is facing growing challenges: Greater efficiency, increased flexibility and optimal use of space are in high demand. Autonomous mobile robots (AMRs) offer an innovative solution for simplifying internal transport and automating rapidly. Discover more about AMRs, their possible applications and the advantages they bring.

Key Takeaways

  • AMRs move independently and use advanced sensor technology and intelligent software to make decisions in real time.
  • They allow simple, flexible planning of internal transport networks.
  • AMRs can be quickly integrated without any structural changes.
  • They can optimize warehouse processes, lower costs and offer the flexibility and scalability needed for the future.
  • KNAPP’s Open Shuttles automate the transport of containers, pallets, magazines and trays efficiently and flexibly.

What is an autonomous mobile robot (AMR)?

Autonomous mobile robots are a type of driverless industrial truck. Without the need for human control, they navigate within a defined environment and respond in real time. An AMR orients itself with a digital plan of a warehouse and uses modern sensor technology along with cameras and artificial intelligence to independently detect and avoid obstacles.

Autonomous mobile robots for transport within facilities
One of the innovations that have fundamentally changed manufacturing is the autonomous mobile robot – AMR for short. Its ability to dynamically respond to changes in the environment makes it ideal for use in modern logistics centers and production halls.

Find out how AMRs differ from other automated guided vehicles (AGVs) in our blog, AMRs and AGVs: Two Automated Guided Vehicle Systems, Compared.

Autonomous mobile robots: Application and requirements

AMRs are established as indispensable helpers in many different sectors. They are widely used in the manufacturing, automobile and electronics industries as well as in the food, pharmacy, mail order and e-commerce sectors. In this blog, we concentrate on how autonomous mobile robots are used in manufacturing. Here, AMRs are involved in many types of transport work thanks to their innovative technology, advanced sensor systems and intelligent software.

  • Establishing flexible internal transport networks
  • Supplying work stations and production lines just in time
  • Supporting the picking process, quality control and sorting
  • Connecting directly to storage systems
  • Complementing an existing conveyor system
  • Supplying kanban, flow and pallet racks

On the road to smart factories, AMRs are indispensable. A smart factory uses automation solutions such as AMRs and automated storage systems to optimize the production processes. Read more about it in our blog Smart Manufacturing: The Future of Production.

Before deciding to use an AMR in your production or storage facility, the following criteria should be considered:

Criterion AMR well-suited AMR less well-suited
Environment Dynamic work environment and variable workload Static or very simple environment with permanent transport paths
Tasks Routine tasks and tasks prone to error Highly complex, unique tasks
Transport
requirements
Many transport tasks and safety requirements Few transport requirements, easily handled by a person or using other technologies
Flexibility Flexibility is needed for future changes and permanent conveyors should be avoided No flexibility needed, conveyors as a permanent element
Infrastructure Structured building with sufficiently wide paths and an available IT infrastructure Complex grounds with unstructured spaces, outdoor transport, insufficient Wi-Fi in the halls
Throughput Medium to low throughput, long distances High throughput in small spaces

In summary, the use of autonomous mobile robots must always be adapted to the respective operational requirements and environmental conditions. AMRs offer significant benefits in a dynamic work environment with repetitive and physically demanding tasks. In a warehouse with highly complex tasks and high throughput, however, they are not the best solution.

Top 5 benefits of autonomous mobile robots

But what makes AMRs so unique and attractive for companies, regardless of their size? Here are the advantages of AMRs summed up:

1) Increased productivity and efficiency
AMRs can quickly handle routine transport jobs, operating 24/7. This maximizes operating time and overall productivity. By continuously analyzing data and making optimizations, processes improve continuously, and bottlenecks are avoided.
2) Flexibility and adaptability
Autonomous mobile robots adapt easily to new tasks and environments, without comprehensive changes to the infrastructure being needed. They are also easy to configure: New processes, stations and routes can be easily added.
3) A cost-effective way to reduce errors
By automating routine tasks, you effectively lower labor costs, optimize material flow and reduce the errors associated with manual handling. Furthermore, the costs involved in the investment amortize rapidly. Your employees are then free to concentrate on tasks associated with value creation.
4) Scalable system
AMRs not only integrate into the existing infrastructure without any problem, but also allow your fleet to grow as your company grows. Simply add another AMR when the time is right, or reduce your fleet or redeploy them elsewhere when in-house needs change.
5) Safety
Advanced safety systems and state-of-the-art sensor technology ensure absolute safety around the AMRs, preventing accidents involving people or other transport vehicles and machines.

The great advantage is that, compared to traditional industrial robots and static conveyors, our AMRs can be adapted to changing processes quickly. They optimize the workflow, reduce costs and improve work safety.

Special features of the KNAPP AMRs

The Open Shuttle by KNAPP boasts a range of standard features and add-ons that are tailored to the requirements of the manufacturing, food retail and distribution logistics sectors.

1 I Integrated lifter for different drop-off and pickup heights

Our autonomous mobile robots can be equipped with a lifter that allows them to pick up and drop off loads at different heights. Open Shuttles manage 550 mm to 1,500 mm (21.65 to 59.06 in) or 0 to 1,200 mm (0 to 47.24 in) and act as a direct link to automated storage systems, such as our Evo Shuttle.

Controlling autonomous mobile robots with software and AI

The performance of an AMR depends directly on the software that controls it. Modern AMRs use AI and machine learning to analyze their environment and make decisions in real time. These technologies allow the robots to adapt to new situations without requiring manual reprogramming. The most important software elements are:

Navigation software:
This allows the AMR to determine its position, plan routes and avoid obstacles. These systems, including the one from KNAPP, are often based on SLAM (Simultaneous Localization and Mapping). The software allows the robots to create a map of their environment in real time and to keep it updated.
Fleet management:
Many companies need more than just one AMR – they need a fleet of robots to handle their work. Fleet management software monitors and controls the movements of the robots, preventing collisions and optimizing workflows. KNAPP offers the fleet control software KiSoft FCS for controlling, monitoring and optimizing manual and automated industrial trucks.
Integration into the warehouse management system (WMS):
In order to reach maximal efficiency, AMRs are often integrated into the existing warehouse management system. This allows them to respond directly to orders, automatically picking or storing the goods accordingly. To meet this requirement, KNAPP offers KiSoft and SAP®EWM by KNAPP, a logistics suite that connects everything and also interacts perfectly with KiSoft FCS.
Software for AMRs
The Open Shuttle autonomous mobile robots manage transport resources and orders independently through the fleet control software, KiSoft FCS. This allows the AMRs to intelligently plan the best route to take to get to the target.

We chose the KNAPP AMRs because their system allows us a very high level of autonomy. The new automation system sets us up for making changes at our location independently, as well as being able to expand our production cells. This makes our overall operation faster and more cost-efficient than it would be with other systems.
