Pull up a truck to the dock door of a DC in 2021, and the lift truck that arrives to unload your pallets might have a driver behind the wheel ... or it might have a bundle of sensors. Inside the building, the hand reaching into a tote to retrieve an item for an order might be connected to a human laborer … or it might be attached to a mechanized arm. Over at the racks of stored goods, the bar-code scanner taking inventory might be wielded by a warehouse employee … or it might be mounted on a hovering drone.
Logistics robots are here to stay, and they're whirring around every corner of the DC, helping companies handle the surge of e-commerce orders triggered by the pandemic. But demand for warehouse robots began long before the coronavirus reached U.S. shores in 2020. Companies have been eyeing the technology for years, drawn by its potential on a number of fronts. In particular, they've been looking at robots as a way to compensate for labor shortages and help them train temp workers during peak season, match Amazon's shipping speed, and pack more inventory into their facilities.
All robots are not the same, though. Like the animals on a farm, bots come in all combinations of shape, size, speed, strength, and smarts. This primer on robotic technology can help "farmers" determine which of the many options best meets their needs.
AUTOMATED STORAGE AND RETRIEVAL SYSTEMS
An automated storage and retrieval system (AS/RS) can automate many warehouse processes by storing, delivering, tracking, and replenishing inventory through a computer-controlled process that automatically deposits and retrieves loads from set storage locations in a set of steel racks.
Installing an AS/RS is a long-term investment, requiring a substantial upfront cost, a dedicated area of the warehouse, and specialized racks and totes for many models. Furthermore, because each unit is designed for goods of a specific size and shape, these systems lack the flexibility to handle variation.
But once the unit is up and running, an AS/RS can deliver high throughput speeds, reducing the size of the workforce needed to move goods around the facility, eliminating fulfillment errors, and easily coping with inventory challenges like high SKU (stock-keeping unit) counts, high-value goods, or heavy items.
These AS/RS solutions come in many varieties, including models with cranes reaching between aisles to fetch racked goods, units with shuttles that glide above the storage racks or whir between them in three dimensions, and vertical storage carousels and vertical lift modules that store goods in a self-contained unit.
Benefits:
Maximize use of warehouse floor space by supporting dense inventory storage
Safely store high-value inventory and reduce inventory loss
Reduce labor costs by slashing the time needed to stock and retrieve goods
Deliver goods to employees at ergonomic workstations for high-speed fulfillment
Applications:
Parts storage and order picking applications
High-throughput operations that require fast picking, such as e-commerce or grocery
AUTOMATED GUIDED VEHICLES
Automated guided vehicles (AGVs) have roamed warehouse aisles for decades, carrying inventory along set routes demarcated by wires or magnets embedded in the concrete floor, bar-code stickers affixed to storage racks, or wireless signal beacons mounted on walls.
That system allows vehicles like self-driving tugs, forklifts, and pallet jacks to steer themselves between predetermined indoor locations and shuttle goods from point to point. Recent upgrades have added sensors like computer-vision cameras or LiDAR (light detection and ranging) technology to enhance their ability to detect obstacles and avoid collisions. But AGVs currently don't have the capability to change their routes, adapt to new workflows, or communicate with other vehicles to optimize the movement of materials.
However, vendors say the lines between AGVs and their cousins, autonomous mobile robots (AMRs), are beginning to blur. For example, advances in machine learning may soon allow AGVs to "think" their way around obstacles and handle new workflows.
Benefits:
Reduce labor requirements by moving inventory without requiring a vehicle driver
Avoid injuries caused by heavy lifting and repetitive motion
Save time that workers would have spent in manually moving goods
Applications:
Repetitive workflows that follow established routes
Contactless movement and storage
Round-the-clock, three-shift operations
AUTONOMOUS MOBILE ROBOTS
Autonomous mobile robots (AMRs) are similar to AGVs in that they can safely transport inventory around a warehouse, but they also include advanced features that greatly expand the variety and complexity of the tasks they can perform.
The chief differentiator between AMRs and AGVs is that AMRs do not require pre-installed infrastructure to navigate through a crowded warehouse. Instead, they use an array of sensors to detect, map, and memorize the facility's features, using approaches like simultaneous localization and mapping (SLAM) technology. And they do it all while avoiding obstacles with real-time reflexes; communicating with other AMRs, warehouse management systems (WMS), and other software platforms; and even collaborating with human employees on picking and fulfillment tasks.
As one of the fastest-developing types of warehouse technology, AMRs seem to gain new capabilities every year. Many models can make their own map of an unfamiliar warehouse, then share that map with other robots, enabling companies to scale up their operations by simply rolling additional AMRs onto the floor, avoiding setup and installation hassles. Other models can use cloud-based software to optimize their path through the warehouse, detecting traffic jams or blockages and choosing new routes to get the job done faster.
The progenitor of this class was a squat orange robot developed by Kiva Systems to carry racks of goods to waiting human workers in what's known as a goods-to-person workflow. The technology worked so well that it was promptly taken off the market after Amazon.com purchased the company in 2012 and took it private.
But generations of new models have followed. Some have replicated the original Kiva design, while others have added new capabilities and attachments, such as spinning table-top belts for sliding parcels on and off conveyors, and tablet computers for communicating with human workers.
Other AMRs known as autonomous picking carts—or zone picking robots—operate on a robot-to-goods model. In that workflow, they automatically meet up with warehouse associates at specific racks or aisles, provide instructions on which goods to pick and which tote to place them in, and then whisk the completed order to another staffer at a packing station.
Benefits:
Support social distancing in warehouses by shuttling between workers
Reduce travel distances for DC order pickers
Enable workers to pick far more items per shift than in manual workflows, thus helping DCs cope with labor shortages and peak-season demands
Applications:
High-volume DCs that need efficient workflows
Training new hires and temp workers through tablet computers mounted on the machine
Increasing pick accuracy by delivering clear instructions via tablet PCs
AUTONOMOUS INVENTORY BOTS
Autonomous inventory bots are essentially AMRs that count inventory on shelves instead of delivering goods to people or places. Outfitted with an array of sensors—computer vision, bar-code scanners, radio-frequency identification (RFID) readers, and more—they steer themselves around indoor facilities, constantly updating the DC's records on the quantity and location of goods. Inventory bots have also been deployed in retail and grocery stores, where inventory records are notoriously inaccurate.
Benefits:
Provide inventory counts that are more accurate than humans' counts
Avoid out-of-stock items by constantly updating records
Allow inventory counts to be conducted at any hour, such as during late-night shifts when the building is empty
Applications:
Tracking jumbled goods on retail and grocery shelves
Counting inventory in large warehouses
ROBOTIC PICKING ARMS
Robotic picking arms have long been a familiar sight in industrial factories, where they perform precision tasks in automobile assembly or electronics manufacturing operations. But they're a relatively new entrant into the world of distribution operations, where they're starting to attract interest for their potential to boost fulfillment speed and accuracy.
Each unit includes a robotic arm with multiple joints and some type of "hand," known in the business as an "end-effector." The end-effector typically includes grasping fingers, suction cups, or some combination of the two, allowing it to seize objects ranging from the heavy (boxes on a pallet) to the light (garments packed in a plastic bag or small each-picks in a tote). Robotic arms rely on computer-vision sensors and artificial intelligence (AI) to help them recognize specific items and determine the best way to grasp them.
Benefits:
Can work around the clock
Increase picking capacity
Free workers from repetitive tasks
Applications:
Receiving operations, depalletizing tasks, and placing goods on conveyors
Fulfillment tasks, such as pick, pack, and ship
Singulating cartons from a pallet onto a conveyor
DRONES
Flying drones and unmanned aerial vehicles (UAVs) are some of the latest entrants into the ranks of logistics robots, currently found mostly in pilot projects and innovation labs.
Like the birds in a forest, they vary greatly in size, speed, and capability. Some have whirring helicopter blades that allow them to hover, while other models look more like miniature propeller planes, able to soar on fixed wings.
Large warehouses might use drones indoors for inventory counting—a task they typically carry out by hovering over tall racks and scanning goods. But drones are also used out in the wider world, where they've been deployed to track trailers around truck yards, inspect infrastructure such as train tracks, and perform last-mile deliveries.
Benefits:
Provide sensor access to high warehouse racks that would otherwise be accessible only by high-reach lift trucks
Enable the delivery of small, urgently needed items such as medical supplies
Applications:
Inventory counting
Last-mile delivery of lightweight objects
ONLY THE BEGINNING
Choosing the best type of warehouse robot for your facility is a complex decision—considerations range from your budget and return on investment (ROI) goals to the condition of the building and your IT (information technology) infrastructure to labor availability in your particular market. But when you find the right solution, the benefits can be huge.
And if your perfect solution wasn't on this list, don't be discouraged. Chances are a robotics vendor somewhere is already working on a new design that will meet your needs. Recent technological advances have allowed developers to flex their creative muscle and respond to changing market conditions at almost lightning speed (think of the disinfecting bots that hit the market within weeks of the pandemic's arrival in the U.S., for example). It's safe to say robots have only just begun to find their niche in logistics.
Nearly one-third of American consumers have increased their secondhand purchases in the past year, revealing a jump in “recommerce” according to a buyer survey from ShipStation, a provider of web-based shipping and order fulfillment solutions.
The number comes from a survey of 500 U.S. consumers showing that nearly one in four (23%) Americans lack confidence in making purchases over $200 in the next six months. Due to economic uncertainty, savvy shoppers are looking for ways to save money without sacrificing quality or style, the research found.
Younger shoppers are leading the charge in that trend, with 59% of Gen Z and 48% of Millennials buying pre-owned items weekly or monthly. That rate makes Gen Z nearly twice as likely to buy second hand compared to older generations.
The primary reason that shoppers say they have increased their recommerce habits is lower prices (74%), followed by the thrill of finding unique or rare items (38%) and getting higher quality for a lower price (28%). Only 14% of Americans cite environmental concerns as a primary reason they shop second-hand.
Despite the challenge of adjusting to the new pattern, recommerce represents a strategic opportunity for businesses to capture today’s budget-minded shoppers and foster long-term loyalty, Austin, Texas-based ShipStation said.
For example, retailers don’t have to sell used goods to capitalize on the secondhand boom. Instead, they can offer trade-in programs swapping discounts or store credit for shoppers’ old items. And they can improve product discoverability to help customers—particularly older generations—find what they’re looking for.
Other ways for retailers to connect with recommerce shoppers are to improve shipping practices. According to ShipStation:
70% of shoppers won’t return to a brand if shipping is too expensive.
51% of consumers are turned off by late deliveries
40% of shoppers won’t return to a retailer again if the packaging is bad.

The global air cargo market’s hot summer of double-digit demand growth continued in August with average spot rates showing their largest year-on-year jump with a 24% increase, according to the latest weekly analysis by Xeneta.
Xeneta cited two reasons to explain the increase. First, Global average air cargo spot rates reached $2.68 per kg in August due to continuing supply and demand imbalance. That came as August's global cargo supply grew at its slowest ratio in 2024 to-date at 2% year-on-year, while global cargo demand continued its double-digit growth, rising +11%.
The second reason for higher rates was an ocean-to-air shift in freight volumes due to Red Sea disruptions and e-commerce demand.
Those factors could soon be amplified as e-commerce shows continued strong growth approaching the hotly anticipated winter peak season. E-commerce and low-value goods exports from China in the first seven months of 2024 increased 30% year-on-year, including shipments to Europe and the US rising 38% and 30% growth respectively, Xeneta said.
“Typically, air cargo market performance in August tends to follow the July trend. But another month of double-digit demand growth and the strongest rate growths of the year means there was definitely no summer slack season in 2024,” Niall van de Wouw, Xeneta’s chief airfreight officer, said in a release.
“Rates we saw bottoming out in late July started picking up again in mid-August. This is too short a period to call a season. This has been a busy summer, and now we’re at the threshold of Q4, it will be interesting to see what will happen and if all the anticipation of a red-hot peak season materializes,” van de Wouw said.
The report cites data showing that there are approximately 1.7 million workers missing from the post-pandemic workforce and that 38% of small firms are unable to fill open positions. At the same time, the “skills gap” in the workforce is accelerating as automation and AI create significant shifts in how work is performed.
That information comes from the “2024 Labor Day Report” released by Littler’s Workplace Policy Institute (WPI), the firm’s government relations and public policy arm.
“We continue to see a labor shortage and an urgent need to upskill the current workforce to adapt to the new world of work,” said Michael Lotito, Littler shareholder and co-chair of WPI. “As corporate executives and business leaders look to the future, they are focused on realizing the many benefits of AI to streamline operations and guide strategic decision-making, while cultivating a talent pipeline that can support this growth.”
But while the need is clear, solutions may be complicated by public policy changes such as the upcoming U.S. general election and the proliferation of employment-related legislation at the state and local levels amid Congressional gridlock.
“We are heading into a contentious election that has already proven to be unpredictable and is poised to create even more uncertainty for employers, no matter the outcome,” Shannon Meade, WPI’s executive director, said in a release. “At the same time, the growing patchwork of state and local requirements across the U.S. is exacerbating compliance challenges for companies. That, coupled with looming changes following several Supreme Court decisions that have the potential to upend rulemaking, gives C-suite executives much to contend with in planning their workforce-related strategies.”
Stax Engineering, the venture-backed startup that provides smokestack emissions reduction services for maritime ships, will service all vessels from Toyota Motor North America Inc. visiting the Toyota Berth at the Port of Long Beach, according to a new five-year deal announced today.
Beginning in 2025 to coincide with new California Air Resources Board (CARB) standards, STAX will become the first and only emissions control provider to service roll-on/roll-off (ro-ros) vessels in the state of California, the company said.
Stax has rapidly grown since its launch in the first quarter of this year, supported in part by a $40 million funding round from investors, announced in July. It now holds exclusive service agreements at California ports including Los Angeles, Long Beach, Hueneme, Benicia, Richmond, and Oakland. The firm has also partnered with individual companies like NYK Line, Hyundai GLOVIS, Equilon Enterprises LLC d/b/a Shell Oil Products US (Shell), and now Toyota.
Stax says it offers an alternative to shore power with land- and barge-based, mobile emissions capture and control technology for shipping terminal and fleet operators without the need for retrofits.
In the case of this latest deal, the Toyota Long Beach Vehicle Distribution Center imports about 200,000 vehicles each year on ro-ro vessels. Stax will keep those ships green with its flexible exhaust capture system, which attaches to all vessel classes without modification to remove 99% of emitted particulate matter (PM) and 95% of emitted oxides of nitrogen (NOx). Over the lifetime of this new agreement with Toyota, Stax estimated the service will account for approximately 3,700 hours and more than 47 tons of emissions controlled.
“We set out to provide an emissions capture and control solution that was reliable, easily accessible, and cost-effective. As we begin to service Toyota, we’re confident that we can meet the needs of the full breadth of the maritime industry, furthering our impact on the local air quality, public health, and environment,” Mike Walker, CEO of Stax, said in a release. “Continuing to establish strong partnerships will help build momentum for and trust in our technology as we expand beyond the state of California.”
