What is warehouse automation today?
Warehouse automation is the process of automating the movement of inventory in a warehouse – from receiving to picking, packing, and shipping.
Warehouses are a critical part of any supply chain, vulnerable to issues that can impact customers and profits. Good warehouse management has always meant organizing space, controlling inventory, and filling orders on time. Today, technology and AI are making it easier to do these things well, replacing guesswork and slow processes with confidence and speed. Teams are now equipped with the data and tools they need to keep warehouses running smoothly.
Types of warehouse automation
Warehouse automation involves the tools, technology, and digital solutions that help you run a warehouse. It’s important to distinguish between digital automation and physical automation:
Digital automation involves advanced warehouse warehouse management systems (WMS) that go beyond tracking inventory and orders. Modern WMS are getting better at integrating warehouse control system (WCS) features, which help coordinate the real-time activities of automated equipment for smoother operations. These advanced systems combine traditional WMS and WCS capabilities for a more integrated and efficient way to manage your warehouse.
Physical automation deals with the hands-on tasks of moving and handling goods, using technologies like automated guided vehicles (AGVs), conveyor belts, and robotics. These solutions help automate tasks such as moving products, sorting, and packaging, reducing the need for manual labor while speeding operations.
How does a fully automated warehouse work?
A fully automated warehouse is like a carefully choreographed dance, where all the steps and movements are coordinated and unified on a centralized platform. When a pallet arrives, it is received into inventory, sorted, and stored. But to do this efficiently, the entire process must also be organized for the later picking, packing, and shipping of those items with equal speed and efficiency. This is accomplished by integrating a flexible network of sensors, robotics, and advanced software solutions that are coordinated by smart automation.
Warehouse automation technology and robots
Whether you’ve have achieved end-to-end warehouse automation or you’re at an early stage in your digital and technological transformation, you will find that the best automation outcomes are achieved with a collaborative range of integrated technologies:
AI-powered analytics
AI and machine learning allow for the advanced and real-time analysis of vast amounts of warehouse and supply chain data, optimizing inventory levels, predicting trends, and aiding in strategic decision-making.
Automated storage and retrieval systems (AS/RS)
These systems are crucial in high-density storage environments. They utilize tools like automated vehicles and robotic arms to store and retrieve items efficiently, maximizing space utilization and reducing retrieval times.
Automated guided vehicles (AGVs)
AGVs are key in transporting goods within the warehouse. Following predefined routes, they ensure consistent and reliable movement of items.
Autonomous mobile robots (AMRs)
AI and machine learning gives AMRs the ability to navigate autonomously and learn as they go. Connected to each other and to control systems over an IoT network, AMRs operate in real time and can respond intelligently to changing environments and challenges.
Warehouse drones
These are essentially flying AGVs or AMRs. In crowded warehouses, drones zoom around undeterred, getting a “bird’s eye” view of the space to help streamline and simplify tasks.
Goods-to-person (GTP) systems
Instead of the traditional method of the workers moving to the goods, GTP systems bring the goods directly to the workers, significantly enhancing picking efficiency and reducing physical strain.
Pick-to-light and put-to-light systems
These use lights and digital displays in warehouse storage shelves and areas, helping to guide workers where to find items – and where to put them once they have.
Voice picking and tasking
By integrating voice commands, these tools offer a hands-free, efficient method for picking and tasking, enhancing safety and operational efficiency.
Automated sortation systems
These systems sort and organize products at high speeds using conveyors and sensors, streamlining the process from receiving to shipping.
RFID technology
Utilizing radio frequency identification, RFID systems track and manage inventory by embedding tags with digital data, boosting accuracy, and reducing manual labor in inventory management.
Collaborative robots (cobots)
Cobots represent the synergy between human capabilities and robotic efficiency. They work alongside human workers, enhancing productivity while maintaining flexibility.
