How does AutoStore work?

Rather than using traditional shelving to store products in a warehouse, which wastes space due to the requirement of walkways and aisles between shelves, AutoStore’s design improves storage capacity and density. Bins containing products are stacked directly on top of and next to each other in a condensed, space-efficient grid-style system.

Order-picking robots travel on the system’s top layer to retrieve the bins, making it possible to build the grid around columns, on mezzanines, and on top of floors with varied elevations. Therefore, this flexible and modular robotics solution can increase warehouse floor space utilization by 400 percent compared to static shelving. It can be adapted or scaled as space requirements increase to maximize efficiency, while AutoStore’s innovative order fulfilment capabilities also accommodate your company’s growth.

The AutoStore system design allows for growth in line with your specific business needs – each attribute of an AutoStore can be adapted independently from the others. It’s possible to add more robots or ports if you require more throughput due to growth in demand. If you have launched a new product range and need more storage, you can extend the grid and add the required bins into the system. All of these can take place while the rest of the system remains operational.

Taking advantage of the Pareto principle

In general warehousing, conducting an ABC analysis of your products is obligatory. However, AutoStore takes advantage of what is known as the Pareto principle – where 80 percent of order lines are associated with 20 percent of stock-keeping units (SKUs), which is prevalent in eCommerce order profiles. So, AutoStore operates on the elementary rule that every time a bin is presented to a port and then returned to the grid, it always returns to a random top location. Therefore, bins containing popular or fast-moving SKUs will already be sitting at the top of the grid, ready for the next batch of consumer orders.

This also means that the system will reconfigure itself naturally when there is a change in the SKU profile, such as for fashion items. For example, jumpers and warm clothing make up the most ordered SKUs in winter, meaning they will be on top of the grid. As the weather changes and we move into warmer weather, customers may order sunglasses or sandals. When ordered for the first time after a period of inactivity, these items may need to be “dug” up as they have sunk down the grid to the bottom of a stack. This is what the Pareto principle dictates.

However, the moment these items are retrieved for that first order, the SKUs are placed back on top of the grid. Any subsequent orders will automatically come from the top of the grid now that the weather has changed, thereby avoiding a repeat of the initial preparation work.

Always a step ahead

One of the most important things to keep in mind is that the AutoStore warehouse robots are working ahead of the operators to prepare for the next wave of orders. A worst-case scenario could be that a required bin is located at the bottom of a stack of bins in the most far-flung corner of the grid from where the ports are. Retrieving the bin would take approximately three-and-a-half minutes – a lot less than walking to the most faraway shelf in a traditional warehouse. Yet, the retrieval activity happens roughly 30 minutes before the bin gets delivered to an operator for picking. Consequently, the operator at the port has absolutely no sense of the difference between a fast-moving product and a slow-moving one.

All of the above means that in normal ecommerce operations, 80 percent of the order lines that need to be picked will come from a bin located in the top two to three layers of the AutoStore grid. Only on rare occasions will robots have to dig to the bottom of a stack to retrieve slower-moving bins, thereby negating the need for the ABC analysis.

What makes up an AutoStore solution?

While you can customize each AutoStore solution to match unique operational needs, they all start with six basic components that easily integrate into any existing facility.

These are:

  • Robots
  • Grid
  • Controller
  • Ports
  • Bins
  • Software

Let’s look at each of these in more detail.

AutoStore delivery robots

The robots are the foot soldiers of the AutoStore system. They drive, dig, collect, and deliver bins to workstations incessantly and tirelessly. All models of AutoStore robots have eight wheels for five-directional movement. This way, they can reach any point in the grid to pick, transport and place bins. The robots pick and deliver goods in the smartest available routes on the grid as calculated by the controller. A fleet of robots can operate 24/7 and have smart charging criteria that allow them to take the opportunity to replenish their energy when activity on the grid is not at its busiest.

AutoStore offers the Red Line robot (R5 and R5+) and the Black Line robot, the B1. The Red Line robots are the workhorses of the fleet and the most established robot in the range, making up over 75 percent of the existing AutoStore systems globally.

The award-winning, fifth-generation Red Line robots use energy-efficient drives and a recuperation system, enabling them to operate with minimal interruption. When the battery is low or during downtime hours, they move to chargers located at the edge of the grid. These robots are still industry leaders after more than 20 years on the market.

The new, slimmed-down, lighter B1 robots run on lithium-ion batteries and direct drive wheels for special and dedicated applications. This robot has greater acceleration and top speed, allowing it to reach its destination quicker. Like the R5+ robot, it is built to handle the taller 425mm bin, but in the B1, the bin is transported within the cavity of the robot’s body to reduce its operational footprint on the grid. The slimmer body profile creates space for tighter and busier robot clusters. These robots require no fixed station for charging. Instead, the patented BattPack technology enables them to exchange batteries at the BattPack stations within 30 seconds at any time.

Whether the R5, the B1, or a combination, you can assemble a team of AutoStore warehouse robots tailor-made for your needs.

AutoStore structural grid

Optimized for cube-based storage, the AutoStore grid provides unparalleled storage density and product security. It’s made of lightweight aluminum profiles, making the grid flexible to design and easy to install. The size and shape of the grid are only restricted by the warehouse around it, ensuring optimal space usage.

The grid consists of columns that make up the cells inside the grid, with each cell containing multiple stacked bins. Topping off the grid are tracks running in X and Y directions so that the robots can access any cell.

AutoStore (AS) controller

The controller is the command center of AutoStore and is responsible for two essential actions within the AutoStore grid:

  • the location of every bin, robot, and port
  • looking after the traffic management and route planning of every task executed by each robot

An important distinction is that the AutoStore controller has no idea what products are located within a single bin, how many units of that SKU are contained within the bin, or what activity is happening to a bin when the system presents it to a port. Instead, Element Logic’s eManager software platform manages and controls all this information.

AutoStore operator ports

These are the workstations where the AutoStore robots deliver the goods for operators to pick. All AutoStore ports can conduct any operation within the system, whether inbound or outbound order processing or inventory inspection tasks. The only difference between the various ports is what we refer to as the bin exchange time.

AutoStore provides six port modules to match the speed and size of any warehouse or fulfilment center:

  • Conveyor port: Being available in either narrow or wide-side handling allows it to be placed in any orientation or side of the AutoStore. The bin exchange time of the conveyor port is approximately 6-7 seconds. Therefore, the port is more common in operations where the time needed between picking one SKU and the second is longer than the 6-7 seconds, and the number of bins required to complete a single task group is generally quite low. It’s also quite commonly utilized for goods-in operations.
  • Carousel port: Available in wide-side handling only, this port comprises a tri-armed high-speed bin exchange process, typically used in pick-and-pack (one-touch dispatch) operations. It’s larger than the conveyor port and features a built-in work surface that lends itself well to picking, packing, and dispatching orders at the port.
  • Swing port: Swing ports are suitable where the AutoStore grid is located on a mezzanine floor, and the goods are required at ground floor level. The port utilizes an internal bin lift to allow robots to retrieve a bin. The depth at which the port can be placed below the AutoStore grid is adjustable.
  • Relay port: This is the fastest AutoStore port module, typically used in high-speed pick-and-pass operations. Multiple robots deliver to central cells, creating a rapid flow of bins to the operator.
  • Pick-up port: A newly introduced public-facing port that allows shoppers to quickly pick up their online purchases with the help of AutoStore robots.

Fusion port: With a 15-degree forward tilt, a safety hatch, and an integrated pick-to-light system, this port is highly ergonomic, safe to use and helps reduce turnover and increase productivity.

AutoStore storage bins

Measuring 400mm x 600mm on the inside, the bins are the inventory containers of AutoStore. The bins, which can be divided into different-sized compartments with inserts, come in three height options to fit your storage needs: 220mm, 330mm, and 425mm. The tallest is compatible with B1 and R5+.

Unique construction and gentle robot handling make the bins extremely durable and able to withstand many movements over years of service. The world’s first AutoStore warehouse in Norway still uses the bins it installed in 2005.

The bins comprise a stiff top frame with guiding details, a rigid bottom design, four openings for the robot gripper hooks, and ribs designed for stability and top loads. The bin load is up to 30kg. Each bin has a unique ID stored in the AutoStore Controller database matched to a label on the bin, giving it complete control over the contents of each bin at any given time. This allows the controller to know the whereabouts of any bin in the system.
