Autonomous Mobile Robots (AMRs) are self-navigating robots, increasingly found in warehouses and distribution centers. AMRs are used in various industries to provide flexible, efficient and safe material handling, inventory management, and more. As technology advances, the applications and uses of AMR are becoming greater.
While AMRs are also used in industries such as healthcare and hospitals, agriculture, and retail & customer service, their primary application is arguably in warehouses. Let’s look at some of the major ways in which they’re used in warehouses.
The basics of AMRs in warehouses
AMRs help to improve efficiency and productivity in manufacturing and warehousing. They’re commonly used for transporting raw materials, and for both work-in-progress items and finished products. AMRs help reduce manual labor and optimize workflow.
Inventory management is another area where AMRs are helpful. They use sensors and RFID technology to conduct automated inventory checks, ensuring accurate stock levels and reducing human error.
They also help with order fulfillment. In e-commerce warehouses, AMRs are often used to assist in picking and packing orders, helping to speed up the fulfillment process. When enhanced by IO-Link Wireless technology, which streamlines communications with the unit, AMRs become even more productive and efficient in the large warehouse setting.
While AMRs often work independently, they can also collaborate with humans, especially when handling heavy loads is required. This collaborative aspect allows for a flexible and efficient workflow, combining the strengths of both human workers and autonomous robots.
End of arm tooling (EOAT)
Some Autonomous Mobile Robots (AMRs) have the capabilities to operate robotic arms equipped with end of arm tooling (EOAT). These robotic arms can be fitted with various devices such as grippers, welding tools, painting tools, and drilling tools, enabling AMRs to perform a wide range of tasks. Additionally, some AMRs interact with EOAT tooling at stationary workstations, moving to and from these stations as needed to complete specific tasks.
EOAT can also include sensors for introspection or measurement, enhancing the versatility and functionality of AMRs. The ability to use EOAT makes AMRs more valuable in automation, as they can perform diverse tasks and contribute significantly to the efficiency and productivity of warehouse operations.
How might AMRs be used in the future as technology and AI progress?
As technology and AI continue to evolve, AMRs in warehouses are poised for significant advancements. AMRs are expected to incorporate more sophisticated AI, enabling them to make complex decisions autonomously. They may increasingly use machine learning algorithms, which will allow these robots to optimize their routes in real-time, adapting to changing warehouse conditions and order priorities. This will enhance efficiency and responsiveness in dynamic environments.
AMRs’ ability to recognize and handle a wide variety of items will continue to improve, and potentially eliminate the need for standardized packaging or barcodes. This could lead to more flexible storage solutions and faster processing times.
Swarm intelligence – a type of AI inspired by the collective behavior of social insects and animals that work in groups – may be implemented. This could allow multiple AMRs to collaborate seamlessly on complex tasks, with robots working in tandem to pick, pack, and ship items more efficiently than ever.
A rather more sci-fi movie-esque possibility is the potential of AMRs dialoguing with human workers. They may engage in troubleshooting conversations, helping to further improve operational efficiency and the safety of workers.
Integration with IIoT (Industrial Internet of Things) devices and predictive analytics could enable AMRs to anticipate inventory needs and automatically reorder stock. This proactive approach could minimize stockouts and overstock situations, optimizing inventory levels.
A 2022 paper in Science Direct on IoT said that “scholars have argued that IoT has the potential to help mitigate the supply chain risks emerging from disruptions through warehousing and logistics”.
IoT and IIoT devices can detect the presence of objects and obstacles, helping AMRs navigate their surroundings safely.
Warehouses which operate around the clock could further be helped by AMRs as battery times improve. The robots may be working 24/7.
The Final Word
AMRs are transforming warehouse operations by automating repetitive tasks such as picking, packing, and inventory management. AI is expanding the future possibilities for AMRs and will make them even more valuable for warehouses.
