1. Introduction: Mobile Robots in Intralogistics – Current State and Perspectives

The mobile robotics market is rapidly developing in the warehouse logistics sector, with Autonomous Mobile Robots (AMR) and Automated Guided Vehicles (AGV) becoming increasingly common solutions. The adoption of these technologies is driven by key factors such as rising labor costs, an increasing shortage of workforce, and continuous pressure to enhance efficiency and accuracy in warehouse operations.¹. Data indicates that the labor shortage is one of the primary reasons for automation interest. A lack of available workforce leads to higher employment costs and can result in task execution delays, prompting businesses to seek alternative solutions, including investments in AMRs and AGVs. Companies delaying automation implementation may struggle to maintain competitiveness in a market where fast and efficient order fulfillment has become the standard.⁵. This article provides an expert analysis of the opportunities and challenges associated with deploying autonomous mobile vehicles in warehouse intralogistics, focusing on areas of optimal and limited usage, implementation costs, technical differences between AGVs and AMRs, control and navigation methods, current trends, integration possibilities with warehouse management systems (WMS/ERP), and our company’s offerings in this field.

2. Optimal and Limited Application Areas of Autonomous Mobile Vehicles in Warehouses

Mobile robots are widely used in various intralogistics areas, significantly improving operational efficiency.

Optimal Application Areas:

One of the most common and efficient applications of AMRs and AGVs is goods transport¹. Continuous and repetitive transport tasks, such as moving pallets, boxes, or carts between receiving, storage, picking, and shipping zones, generate high labor costs and pose injury risks to employees. Automating these processes using AMRs/AGVs leads to significant cost reductions and improved safety.
AMRs can also significantly enhance order picking¹. Using robots in the "goods-to-person" approach, where robots autonomously deliver containers with goods to picking stations, speeds up the process and increases its accuracy. Faster and more precise picking directly translates into higher customer satisfaction and reduced costs associated with errors and product returns³.
Another area where AMRs and AGVs show high efficiency is inventory replenishment¹. Robots can automatically transport goods from high-storage warehouses to picking zones, ensuring continuity in the picking process and minimizing stock shortages.
In high-throughput warehouses, robots are used for sorting packages and goods, automatically directing them to the appropriate shipping zones or further processing¹.
AMRs can also be used for inventory management, autonomously scanning barcodes or RFID tags to monitor stock levels in real time⁸. This allows companies to obtain accurate and up-to-date inventory information, improving stock management.
Some mobile robots are designed for tasks related to cleaning and disinfection of warehouse surfaces, which is particularly important for maintaining high hygiene standards¹.
It is also worth mentioning the possibility of using AMRs and AGVs in extreme environments, such as cold storage¹. Robots can operate in temperatures that are unsuitable for humans, ensuring operational continuity and employee safety.

Limited Application Areas:

Despite many advantages, there are areas where the use of autonomous mobile vehicles may be limited.
Traditional AGVs may face challenges in tasks requiring high flexibility and adaptability, especially in situations where routes or tasks change frequently¹⁴. Rigid AGV routes can cause downtime and require human intervention in case of sudden obstacles or layout changes. On the other hand, AMRs, thanks to advanced navigation systems, offer greater flexibility and can dynamically respond to environmental changes⁸.
Handling non-standard or delicate loads may also pose a challenge for some robots¹⁷. Loads with unusual shapes or requiring special gripping mechanisms may exceed the capabilities of standard robots.
In warehouses with very limited space, some AGV systems, due to their size and turning radius, may require more space to maneuver than traditional workers²⁰.
Tasks requiring complex manipulation, which involve precise movements and decision-making based on context, may be difficult to fully automate¹⁶. In such cases, human-robot collaboration may be necessary.
Environments with highly uneven surfaces or numerous obstacles can make robot navigation difficult, particularly for less advanced models¹⁹. Before deploying robots, it is crucial to assess the floor conditions and adapt the infrastructure if necessary.

3. Cost Analysis of Implementing Mobile Robots: A Long-Term Perspective

The implementation of autonomous mobile robots in a warehouse involves various cost categories that should be considered from a long-term perspective.

Initial (Investment) Costs:

The largest initial cost is usually the purchase price of robots (AGV/AMR). The cost of a single robot can range from a few thousand to hundreds of thousands of dollars, depending on the type, load capacity, navigation technology, and manufacturer¹⁶.
Another major expense is infrastructure costs, which may include the installation of navigation systems (e.g., magnetic tape for AGVs), charging stations, and potential modifications to the warehouse layout¹⁵.
It is also essential to consider integration costs, which involve integrating robots with existing IT systems such as a warehouse management system (WMS) and an enterprise resource planning (ERP) system². These costs may include purchasing additional software and development work.
For more advanced AMR systems, fleet management software may also be required⁴.
Moreover, training costs should be considered, as staff training is necessary for personnel responsible for operating and maintaining the robots¹⁴.

Operational Costs:

Beyond initial expenses, operational costs arise during robot usage, such as electricity costs for battery charging²⁴, maintenance and service costs (regular inspections, repairs, spare parts)¹⁴, and software update costs⁴. It is also important to account for potential downtime costs in case of robot failures¹⁴.

Total Cost of Ownership (TCO) Analysis:

A key metric in assessing investments in mobile robotics is the Total Cost of Ownership (TCO)²³. TCO analysis considers all costs associated with a robot throughout its lifecycle, including direct costs (purchase, implementation, operation) and indirect costs (downtime, lost productivity)²³. Focusing only on the purchase price may lead to underestimating actual expenses and potential financial challenges in the future.

Return on Investment (ROI):

Investing in mobile robots can result in a significant Return on Investment (ROI) due to reduced labor costs, increased efficiency, improved accuracy, minimized product damage, and the ability to operate 24/7¹. In many cases, the payback period for AMR/AGV investments ranges from 12 to 18 months, and in some scenarios, it can be even shorter³³.

Hidden Costs of Non-Automation (Inertia Costs):

Ignoring automation opportunities comes with hidden costs that, in the long run, may exceed the costs of implementing robots⁵. These include loss of competitiveness, increasing operational costs of maintaining manual processes, difficulties in recruiting and retaining employees, human error risks, and scalability limitations. Companies that do not invest in automation may lose market share and struggle to meet growing customer expectations.

Financing Models:

Companies considering mobile robotics implementation have several financing models available, such as purchasing, leasing, and the Robot as a Service (RaaS) model³². The RaaS model can lower the entry barrier for smaller companies by offering flexible payment options based on performance³².

4. AGV vs. AMR: A Detailed Technical Comparison in the Context of Intralogistics

In the context of warehouse intralogistics, it is crucial to understand the technical differences between Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs).

AGV (Automated Guided Vehicles):

AGVs are vehicles that move along predefined routes using various laser navigation systems. Their interaction with the environment is limited – when encountering an obstacle, they usually stop ¹⁴. AGVs are ideal for repetitive transport tasks on fixed, predictable routes ⁹. They are most effective in environments with established material flows.

AMR (Autonomous Mobile Robots):

Unlike AGVs, AMRs navigate autonomously based on environmental maps that they create and update using LiDAR sensors. They utilize navigation systems such as SLAM (Simultaneous Localization and Mapping), vision-based navigation, and laser navigation. AMRs feature advanced obstacle detection and avoidance capabilities as well as dynamic route planning ². Due to their flexibility and adaptability, AMRs are ideal for more complex and dynamic environments, such as order picking or transport in warehouses with changing layouts ¹.

6. Trends and Directions in the Development of AGV/AMR Control and Navigation Technologies

The control and navigation technologies for AGVs and AMRs are constantly evolving, with current trends pointing toward further improvements in capabilities and applications. The use of Artificial Intelligence (AI) and Machine Learning (ML) is becoming increasingly widespread ⁴. AI enhances the robots' ability to make real-time decisions, optimize travel routes, and adapt to unforeseen situations.
Another significant trend is multi-sensor fusion ². Combining data from various sensors, such as LiDAR, cameras, and ultrasonic sensors, allows robots to obtain a more comprehensive and reliable environmental picture, increasing their safety and efficiency.
VSLAM (Visual Simultaneous Localization and Mapping) navigation ⁴ is also advancing, using cameras to create 3D environmental maps and precisely locate the robot. VSLAM can serve as a more cost-effective alternative to LiDAR-based systems.
A key development direction is improving human-robot interaction (HRI - Human-Robot Interaction) ⁴. The goal is to design robots that can safely and efficiently collaborate with humans in warehouse environments, fostering a cooperative workspace.
The use of Digital Twins to simulate and optimize AMR deployments is gaining importance ⁴. Digital Twins allow testing and fine-tuning robotic systems in a virtual environment, accelerating implementation and minimizing operational risks.
Another critical trend is the standardization of interfaces and communication protocols ². This simplifies the integration of robots from different manufacturers with warehouse management systems (WMS) and other automation systems. Standards such as VDA5050 contribute to improving the interoperability of AMR/AGV systems ¹⁰.

7. Integration of AGVs and AMRs with Warehouse Management Systems (WMS) or ERP

The integration of AGVs and AMRs with Warehouse Management Systems (WMS) or Enterprise Resource Planning (ERP) systems is crucial for ensuring smooth intralogistics processes, optimizing material flow, and synchronizing robot operations with overall warehouse logistics ². Without effective integration, the full potential of AMRs and AGVs cannot be realized.
Integration enables real-time data exchange regarding tasks, robot locations, order statuses, and inventory levels. Based on this data, the WMS/ERP system can automatically assign tasks to robots, monitor their performance, and generate reports. Integration also allows robots to synchronize movements with other warehouse equipment, such as conveyors or sorters.
The integration process can present challenges, such as compatibility between different manufacturers' systems (robots, WMS, ERP) ², the complexity of interfaces and communication protocols, the need to adapt existing IT systems, and the cost of integration (software, development work).
Various integration solutions exist, including the use of standard API interfaces, middleware software that facilitates communication between different systems ², and collaboration with experienced providers offering comprehensive integration services ².
