For many small to medium-sized warehouse operations, it can be challenging to find equipment that improves efficiency but doesn’t break the bank or require specialized training. That was the dilemma that faced coffee roaster and distributor Baronet Coffee when it moved its operations to a 50,000-square-foot facility in Windsor, Connecticut. The company, a fourth-generation family-owned and -operated business, has moved several times since its founding in 1930. But this time it ran into a hitch: The large forklifts it was accustomed to using were creating pain points in the new facility.
Specifically, the narrow aisles and high shelving at the new site made it difficult for the company’s forklift trucks to maneuver through the warehouse. Plus, those big, bulky forklifts required operators with specialized training. And while the warehouse has some 35 employees, not all of them had the necessary credentials—which left the operation vulnerable to staffing shortages and bottlenecks.
So Baronet Coffee launched a search for a flexible, low-cost truck that could maneuver in small spaces and would be easy for team members to operate. For help with the selection process, it tapped Big Joe Forklifts, a Downers Grove, Illinois-based company that makes electric lift trucks.
LOW COST, HIGH FLEXIBILITY
The company found what it wanted in Big Joe’s PDSR, an AC walkie reach stacker with power steering that offers a 3,000-pound lift capacity and can reach heights of up to 189 inches. What makes this model ideal for the Baronet Coffee warehouse is the combination of a tight turning radius, low operating cost, and flexibility.
The PDSR uses a pantograph, which is a mechanism that extends the loads being handled beyond the straddle legs to lift or lower products and can be retracted for compact turns. The PDSR also features power steering, side shift, proportional hydraulics, and tilt, which allows operators to reach and side-shift within the narrow racking and in pass-through racking as well.
“Being able to manipulate that pallet, to put it exactly where we need it, has been [a huge plus for the operation],” explained Chase Martin, process engineer at Baronet Coffee, in a video. “The walk-behind truck gives workers the flexibility to go up high or down low or even into the middle of the racking and move product around very easily and safely.”
THE RIGHT FIT
After one day on the job, Baronet Coffee knew the PDSR was the right fit.
“Big Joe’s PDSR really fit the niche really well for us, Martin said in the video. “It’s a unit that isn’t as big as a forklift, and we don’t need people that are certified to drive it. But it does all of the things that we need it to do—getting up high, reaching, tilting side, shifting—to make our day-to-day order picking easier. From an operational standpoint, this is definitely a big success for us.”
Mike Vilarino, business integration manager at Baronet Coffee, agrees, adding that one of the lift truck’s biggest strengths is its ease of use. “People definitely gravitate toward the Big Joe PDSR. It’s very easy to just grab the truck, [go] out on the aisle, pick what you need, and get out of there,” Vilarino said in the video. “The PDSR is a huge value to Baronet due to the fact that the training requirements for operators are minimal—we’re able to get people up to speed very, very fast, and they’re able to perform their job duties in a timely and safe manner.”
Autonomous forklift maker Cyngn is deploying its DriveMod Tugger model at COATS Company, the largest full-line wheel service equipment manufacturer in North America, the companies said today.
By delivering the self-driving tuggers to COATS’ 150,000+ square foot manufacturing facility in La Vergne, Tennessee, Cyngn said it would enable COATS to enhance efficiency by automating the delivery of wheel service components from its production lines.
“Cyngn’s self-driving tugger was the perfect solution to support our strategy of advancing automation and incorporating scalable technology seamlessly into our operations,” Steve Bergmeyer, Continuous Improvement and Quality Manager at COATS, said in a release. “With its high load capacity, we can concentrate on increasing our ability to manage heavier components and bulk orders, driving greater efficiency, reducing costs, and accelerating delivery timelines.”
Terms of the deal were not disclosed, but it follows another deployment of DriveMod Tuggers with electric automaker Rivian earlier this year.
The autonomous forklift vendor Cyngn has raised $33 million in funding to accelerate its growth and proliferate sales of its industrial autonomous vehicles, the Menlo Park, California-based firm said today.
As a publicly traded company, Cyngn raised the money by selling company shares through the financial firm Aegis Capital in three rounds occurring in December. According to forms filed with the U.S. Securities and Exchange Commission (SEC), the move also required moves to reduce corporate spending for three months, including layoffs that reduced staff from approximately 80 people to approximately 60 people, temporarily suspended certain non-essential operations, and reduced or eliminated all discretionary expenses.
In the company’s view, autonomous vehicles are playing a critical role in transforming industrial operations by enhancing productivity and safety.
“This capital infusion strengthens our ability to fund operations, drive commercialization, and continue investing in groundbreaking autonomous vehicle technologies,” Lior Tal, chairman and CEO of Cyngn, said in a release. “With increasing demand for automation solutions, especially in the automotive, heavy machinery and logistics industries, this funding allows us to build on recent momentum, including our upcoming autonomous forklift launch and other strategic advancements.”

He replaces Loren Swakow, the company’s president for the past eight years, who built a reputation for providing innovative and high-performance material handling solutions, Noblelift North America said.
Pedriana had previously served as chief marketing officer at Big Joe Forklifts, where he led the development of products like the Joey series of access vehicles and their cobot pallet truck concept.
According to the company, Noblelift North America sells its material handling equipment in more than 100 countries, including a catalog of products such as electric pallet trucks, sit-down forklifts, rough terrain forklifts, narrow aisle forklifts, walkie-stackers, order pickers, electric pallet trucks, scissor lifts, tuggers/tow tractors, scrubbers, sweepers, automated guided vehicles (AGV’s), lift tables, and manual pallet jacks.
"As part of Noblelift’s focus on delivering exceptional customer experiences, we are excited to have Bill Pedriana join us in this pivotal leadership role," Wendy Mao, CEO at Noblelift Intelligent Equipment Co. Ltd., the China-based parent company of Noblelift North America, said in a release. “His passion for the industry, proven ability to execute innovative strategies, and dedication to customer satisfaction make him the perfect leader to guide Noblelift into our next phase of growth.”
An economic activity index for the material handling sector showed mixed results in December, following strong reports in October and November, according to a release from business forecasting firm Prestige Economics.
Specifically, the most recent version of the MHI Business Activity Index (BAI) showed December contractions in the areas of capacity utilization, shipments, unfilled orders, inventories, and exports. But on the upside, there were expansions in business activity, new orders, and future new orders.
The report gave an array of reasons for those quantitative results, judging by respondents’ accompanying “qualitative responses.” That part of the survey included positive references to lower interest rates, the clear outcome of the election, and improved abilities to retain workers. But those were counterweighed by downside mentions featuring multiple references to tariffs, reflecting broad skepticism in the business community to trade threats made by the incoming Trump administration.
Looking into the future, forecasts for a drop in interest rates and a likely accompanying drop in the dollar are likely to support material handling and manufacturing, which have been held back in recent quarters by high interest rates and a strong dollar, the report from Austin, Texas-based Prestige Economics found.
Likewise, hiring ease was strong in the survey, as a record high 81% of respondents reported hiring in December was “easier” than in November. That improved ease of hiring will be particularly important as the “new orders” category is likely to rise in the year ahead, the report found.
Picture a busy DC, with manually operated forklifts, people, and pallets in constant motion. At the same time, the stationary equipment they interact with, such as conveyors and palletizers, is industriously whirring away. Together, they are performing something akin to a carefully choreographed ballet.
Now add driverless forklifts to the mix. Shuttling along without a human operator on board, they may look like they’re operating independently, but they’re not. They’re actually in constant contact with other equipment and software, making sure they perform their part in the dance at the right moment. Without that ability to communicate, the forklifts—and other warehouse operations—could come to a standstill.
Who, exactly, are driverless forklifts “talking” to, what information are they sharing, and how does that exchange happen? We asked automation experts to explain. They also shared tips on ensuring successful communication between automated lift trucks and other equipment and software.
TWO-WAY COMMUNICATION
Lift trucks that do their jobs without a human operator on board cannot “speak” directly to each other. “As it stands now, there is no peer-to-peer communication or interaction on a forklift-to-forklift basis,” notes David Griffin, chief sales officer for Seegrid, a developer of autonomous lift trucks and AMRs (autonomous mobile robots). There is, however, interaction between forklifts via a centralized fleet manager system (also referred to as a traffic management system or an automation server). This “overarching conductor of the automated system” assigns tasks to each forklift, controls the route the trucks will follow, and manages traffic flow, says Nick McClurg, a sales engineer at forklift maker Hyster Co.
The forklifts communicate with many kinds of material handling equipment, such as robotic palletizers and depalletizers, stretch wrappers, conveyors, automated storage and retrieval systems (AS/RS), and dock equipment. That communication must be bidirectional, says Michael Marcum, senior director of autonomous vehicles at systems integrator Bastian Solutions, a Toyota Automated Solutions company that also makes robotic forklifts. Much of the exchange consists of messages that indicate status—whether or not the two pieces of equipment involved are ready to conduct a transaction. For example, if a forklift will be delivering a pallet to a stretch wrapper, then the wrapper has to tell that forklift, via the fleet manager system, that the load position is empty and the forklift is allowed to set a payload there, Marcum explains. After a pallet has been wrapped, the stretch wrapper will call for a pickup via the fleet manager. Once the forklift picks up the wrapped pallet, it must confirm to the stretch wrapper that it has departed; without that signal, the wrapper cannot receive its next load.
If a truck is not ready for an assigned task, it signals that status to the fleet manager, and the task will be reassigned to another nearby vehicle, says Jayce Nelson, sales manager, North America, for Kion Group’s Linde Automated Solutions, a specialist in automated forklifts and software. When the assigned forklift is ready to approach, say, the end of a conveyor to pick up a load, it uses its vision systems, such as 3D cameras, to align itself with the equipment.
With their control software, robotic forklifts also have the ability to communicate with other warehouse equipment, like fire-detection systems and automated rollup doors. “If a device is capable of sending or receiving electrical signals, then the vehicle can interact with that device via the automation host software,” McClurg says. Even a piece of mechanical equipment could be outfitted with sensors that help it interact with automated forklifts, according to Brian Markison, director of sales for Rocrich AGV Solutions, a joint venture of Mitsubishi Logisnext’s Rocla and Jungheinrich units that specializes in automated guided vehicles.
The capability to communicate with different types of devices enhances warehouse safety, Griffin says, because it enables automated forklifts to talk to safety equipment like pedestrian warning lights and intersection gates. And since the robots constantly transmit their location, the traffic control system can identify developing problems and prevent them. For example, the system will stop an autonomous forklift from entering an intersection that’s occupied by another lift truck. Once the other truck has moved on, the system will give the approaching forklift the “all clear,” he says.
Hardware isn’t the only thing driverless forklifts can talk to; they also are in continual dialogue with various types of software. “Most commercial warehouse software programs today have the capability for two-way communication, and most can be integrated with automated lift truck fleet management software,” observes John Wilkins, a sales engineer for Yale Lift Truck Technologies. The most common are warehouse management systems (WMS) and warehouse control systems (WCS); others include enterprise resource planning (ERP) software, fleet management and telematics systems, and transportation management (TMS) and order management (OMS) systems.
As for how that might work, Rocrich’s Markison gives the example of a WMS sending an order to move a pallet from one location to another. The order typically will include start and completion time, and some indication of the move’s priority. “That order can then be taken into the fleet manager, which will appropriately queue up the tasks that need to be done,” he explains. The forklift must also report completed missions back to the WMS.
HOW TO TALK TO A FORKLIFT
Communication between robotic forklifts and warehouse equipment and software happens in a number of ways. Which method is deployed depends on the equipment and software involved as well as the tasks to be carried out. Each installation is unique in some way, but there are some commonly used approaches.
Some communication protocols are more widely used than others. Examples of those in widespread use include modbus, a serial communication protocol that governs an initiating and a responding device, and CANbus (Controller Area Network), a real-time communication protocol that transmits data to networked industrial controls.
A driverless forklift’s interface with other equipment could be something electromechanical, such as a photo-eye sensor, says Jeff Kuss, product manager–automated solutions at forklift maker and intralogistics specialist The Raymond Corp. A sensor at the end of a conveyor, for instance, could detect the presence of a pallet. That triggers the sensor to create an electrical signal that it sends to a programmable logic controller (PLC). The PLC receives the electrical signal as a digital input and then transmits a message, via ethernet, to the server that controls the automated vehicles. Finally, the server sends the instructions over Wi-Fi to the closest available forklift to “pick up the pallet and take it to Location X.” (Some facilities use Bluetooth or cellular transmission instead of Wi-Fi.) Data that identify loads and trigger a task can also be acquired through IoT (internet of things) platforms, RFID (radio-frequency identification) systems, and barcode scanning.
Another option, Bastian’s Marcum says, is to use infrared-based optic couplers that share bits (binary digits, the smallest units of digital information) as inputs and outputs. When the forklift gets within a certain distance of another piece of equipment, “the two devices can talk to each other, similar to the way a TV remote works,” he explains.
Usually, though, software is a critical intermediary between driverless forklifts and other equipment. It can be complicated. In the case of a WMS, McClurg says, his company’s approach is to send a text or JavaScript Object Notation (JSON) file to the WMS; in exchange, the WMS sends a file to a folder on the localized network that can be accessed by the automation host software. The fleet manager reads the file and executes it. Once the task has been completed, a message is sent to another folder. The WMS opens it, reads it, and, based on its contents, either closes out the order or sends additional instructions.
To ensure that interfacing software programs understand the messages they receive from each other, it’s often necessary to create an application programming interface (API). An API is a comparatively simple type of middleware—or software layer—that acts as a translator, facilitating communication by reformatting messages so they will be intelligible to the receiver. In essence, they are “setting ground rules in terms of what information is passing back and forth and what it means,” Markison explains.
In some cases, more complex middleware may be needed. According to Brice Bucher, senior manager of products at software developer and systems integrator Flexware Innovation, APIs have limitations. In a presentation at the Autonomous Mobile Robotics & Logistics Conference 2024, Bucher noted that APIs don’t address data transformation, protocol conversion, or business logic integration. When each system has different data formats or requires specific protocols, middleware bridges those gaps, he said. Middleware also ensures that data moves between systems without delay, he said. For example, if an AGV completes a task, middleware can instantly trigger updates across systems, so that WMS, ERP, and other systems are aligned in real time.
CAN WE TALK?
Raymond’s Kuss notes that each communication integration will be unique in some way. That’s partly because automated forklift vendors and suppliers of fleet manager systems have proprietary interfaces. On top of that, software with some degree of customization, such as a WMS, may require modifications to the fleet manager system, he explains. What’s more, adds his colleague John Rosenberger, director, iWarehouse Gateway & Global Telematics, “even if we know the format for efficient data transfer, the content of the messages may differ depending on the forklift manufacturer, or it can be different by functionality.”
Mixed fleets with forklifts from different manufacturers present a particular challenge. Seegrid’s Griffin notes that it’s common for facilities to use robots from multiple vendors. Generally, he says, each automated solution has its own proprietary fleet manager software that understands where all units under its purview are and controls their movements. When robots of different brands cannot be confined to separate areas, it’s important that their fleet managers have the ability to communicate, so they can do things like open and close intersections where different types of robots cross paths.
While it is possible for dissimilar fleet managers to talk to each other, that’s easier said than done. “Those systems inherently are not interoperable,” Nelson says. “The need to share information like coordinates, current status, past assignments, and prioritization makes it difficult to assign travel paths.” In addition, if the forklifts are unable to communicate location information and what they are doing, that can lead to deadlock, where the vehicles simply stop—what Yale’s Wilkinson calls “the classic situation: a staring contest between two autonomous vehicles from different OEMs, neither one capable of blinking or losing.”
A solution for some facilities is third-party fleet manager software that’s designed to work in multiple brands of autonomous forklifts; examples include those offered by independent developers such as Kollmorgen, BlueBotics, Navitech Systems, and Flexware Innovation. In fact, some forklift OEMs partner with these and other providers instead of developing their own fleet managers. This opens the way for a fleet to potentially buy different robots utilizing the same control and navigation system, which will reduce complexity to some degree, Marcum says.
Communications with driverless forklifts may become simpler in the near future. VDA 5050, an open-source protocol for communication between AGVs and fleet manager systems, is currently in development. Coordinated by two German industry organizations, one for auto manufacturers and the other for material handling and intralogistics, this universal protocol promises to allow “any mobile robot, regardless of brand, [to] be seamlessly integrated into existing operations,” wrote Alfredo Pastor Tella, who runs the Europe-based AGV Network website, in a LinkedIn post. Pastor Tella wrote that Kollmorgen will introduce VDA 5050 into its robot control software in 2025, but other industry observers have noted that because the protocol’s roots are in European manufacturing and there are still technical issues to be worked out, it may be a few years before it takes hold in the forklift world. When it does, conversations with autonomous forklift fleets will likely become much less complicated to hold.
Tips for success
Want to be sure your driverless forklifts will always “get the message”? Here are some experts’ recommendations for facilitating communication with them:
Involve your IT experts early! They’ll need to identify what relevant data is currently available and where it resides. Make sure they’re comfortable that any APIs and other software meet your company’s security requirements. For cloud-based systems, verify that the vendor and systems integrator will have remote access if they need to service any of the systems or software. (Brian Markison, Rocrich AGV Solutions)
If you’re buying from different manufacturers, find out which supplier has navigation technology on the brands you’re considering and try to stay with a single system if possible. If you have a single platform, you can make a change just once and the entire fleet will receive that modification. If you have two fleet managers, segregate them as much as possible. Wherever they are separate, you’ll only have to change that one, but in shared areas, you’ll have to change both. (Michael Marcum, Bastian Solutions)
When it comes to facilitating communication, software is not always the best answer. Sometimes something simpler, like PLCs that notify equipment through very basic logic, works just fine. And it’s better to start small and integrate each function as you go, rather than try to integrate everything at once. You can tie two systems together and demonstrate the benefits from that, then use the savings to justify and help fund the next piece. (John Rosenberger, The Raymond Corp.)
Conduct testing in real-world scenarios, and make sure legacy software and communication technologies are compatible with the automation. These systems work in a dynamic environment, and a lot changes over time. Calibration tests can make sure everything still aligns correctly. And remember to inform your vendor of changes in things like throughput rates, layout, pallet sizes and configurations, products, and so on. (Jayce Nelson, Linde Automated Solutions)
In most facilities, commands and data are communicated via Wi-Fi, so connectivity and reliability are a top concern. A pre-installation survey to measure Wi-Fi signal availability and strength throughout the facility is an absolute must. Based on those findings, you may need to enhance signal strength and expand capacity and coverage. In some very large facilities, a private wireless network that uses cellular signals may be the best solution.
