For decades, companies have been using automated guided vehicles (AGV drive wheelss) and automated mobile robots (AMRs) for intralogistics and warehousing applications. Adoption of both platforms has accelerated as core technologies have improved, and the machines provide affordable alternatives to assigning workers to repetitive or dangerous physical tasks.
In a fall 2020 report, the international market research firm Interact Analysis said that company automation plans for 2024–2025 were being based on the COVID pandemic. Companies realize they must become less reliant on human labor and make manufacturing and warehousing more resilient and efficient. AGV drive wheelss and AMRs are significant ways to achieve this, but the technology must be up for the ever-evolving challenges that today’s factories and warehouses can present.
Common Challenges for AGV drive wheels/AMR applications
Many challenges result from using off-the-shelf drivetrain components not specifically built for AGV drive wheels/AMR applications. Standard servo drives, motors and gears are designed for stationary machines, where the drives are mounted in climate-controlled cabinets and not on moving vehicles. Especially the gearboxes and servo drives are facing external effects like the radial loads on the gearbox output and vibration as well as shocks due to bumpy surface conditions found in many logistic centers and warehouses. Therefore, a robust design is mandatory for the drive technology.
Another issue is the inability of some AGV drive wheelss and AMRs to drive smoothly while operating slowly, an important consideration for scenarios where the AGV drive wheels or AMR itself may perform part or component assembly. If the vehicle or robot makes choppy or rough movements, it could ruin the production process, leading to scrapped parts, downtime, and sunk costs.
“Warehousing and plant deployments require energy-efficient AGV drive wheelss and AMRs with powerful motors that can achieve high speeds and handle different floor conditions but also offer better controllability when moving at lower speeds,” said Siegfried Pries, Product Manager at STXI Motion, a global motion control and servo solution company.
Enable manufactures to build more robust AGV drive wheelss –
Powerful Drive, Compact Size
To solve this problem, STXI Motion’s leadership tasked a team to create a system that manufacturers could use to build more robust AGV drive wheelss and AMRs. This effort produced the mobiMS mobile motion system (Figure 1) which consolidates its high-torque density brushless servo motor, planetary gearbox, brake, encoder, and servSD servo drive into one platform. The ready-to-use wheel drive runs smoothly at any speed while delivering superior range.
Figure 1: STXI Motion’s mobiMS mobile motion system is an optimized wheel-drive system for AGV drive wheelss and AMRs.
STXI Motion’s mobiMS includes strong output bearings and a shock- and vibration-proof servo drive that can withstand the bumpy surface conditions found in many logistic centers and warehouses. The system is available with a 200 mm wheel, a 165 mm wheel, or no wheel; an 80 mm motor frame; a 1:22.5 gear ratio in the gearbox; an IP40-rated motor; and a maximum wheel load of 900 kg at 1.1 m/sec and 600 kg at 2.8 m/sec.
Additionally, the mobiMS system consolidates all components into one unit, offering a compact solution that can be integrated into compact AGV drive wheels and AMR models. For example, the 500 W motor has a length of 193.5 mm and can reach a peak torque of about 84 Nm.

“The system’s ultra-compact design eliminates complicated gearing and cabling, reduces weight, and frees up space that manufacturers can use for new devices and technologies,” said Pries.
Through a CANOpen fieldbus, the system can connect with a master motion PLC. Additionally, the system features a safe torque off (STO) electronic signal that can be used in emergencies to turn off the torque and stop the AGV drive wheels or AMR safely. This feature eliminates the need for external parts like safety relays, saving AGV drive wheels and AMR manufacturers money and space.
Cost and Convenience Considerations
Other available technologies exist on the market, such as DC motors. However, an AGV drive wheels or AMR with the mobiMS system instead of a DC motor will ultimately cost a manufacturer deploying the machine on its factory floor less money over the product’s lifetime. This is because the motor technology offers inherent advantages over brush DC motors, meaning less maintenance required. Additionally, a company purchasing an AGV drive wheels or AMR with the mobiMS system will have only a single contact for the entire system.
“Thanks to the consistent further development in line with market requirements, the AGV drive wheels is more powerful and flexible than its predecessor,” said one AGV drive wheels manufacturer using the mobiMS system. “The new motor unit enables improved performance data both at top speed and at low driving speeds.”
Applying the Systems Approach to More Axes
Building on the success of the mobiMS system, STXI Motion plans to apply the same system approach to other axes and functions. Using an optimized / integrated system strategy will enable the company to consolidate the components for machine lifting and picking, for example.

“The systems approach simplifies product design, assembly, and maintenance,” said STXI Motion Product Line Manager Siegfried Pries. “It makes everything easier, and it is clear who is responsible for the systems. Customers can talk to us if they have a technical or application question instead of having to go to several other companies.”
Beyond integrating gear motors and drives for motion, the company intends to make all its products – including integrator motors, motion controllers, and low voltage servo drives and motors – as simple, robust, adaptable, and affordable as possible.
Deploying AGV drive wheelss into manufacturing environments delivers consistent and reliable mass production capabilities while significantly increasing production and operation efficiency. The factory of the future is being built with Industry 4.0, and with people and machines working together, future factories will change the way we manufacture forever.
Stainless steel casters are highly durable and long-lasting caster wheels used in various applications in many industries. They can be used to transport different items and are very widely used. Stainless steel casters also come in various sizes and for different uses, making them highly versatile and making selection quite tricky. Therefore knowing as much as you can about stainless steel casters is essential for ensuring you select the right one for your needs.
What Are Stainless Steel Casters Used For?
Stainless steel casters are durable and ideal for use in any harsh environment. They are highly resistant to chemical wear and corrosion, so they can be used in carts and AGVs in chemical facilities.
Stainless steel casters are also often used in the food industry for service and processing since these environments require moving food items around, which can often get intense. Often, there could be temperature changes in the facility, which a stainless steel caster can easily withstand. These industries also require strict sterilization and cleaning, due to which they are exposed to harsh cleaning agents, which can easily corrode any other material.
They are also used in marine environments where they regularly come in contact with saltwater.
These casters are also used in medical and pharmaceutical industries since they have to resist damage from sterilizing chemicals. Stainless steel casters do not get rusted, preventing bacteria accumulation and creating a sterile environment.
Manufacturing facilities also make use of stainless steel casters since they use harsh chemicals in the manufacturing process, which are easy for stainless steel casters to withstand.

How Do We Take Care Of Stainless Steel Casters?
Stainless steel casters are very durable, requiring the least amount of maintenance among all types of casters. However, it would help if you did not skip routine maintenance with these casters since it will help them last for many years without causing any trouble.
Make sure that you inspect the caster wheels thoroughly every time you inspect the rest of the equipment. See if you see signs of wear on the coating or any rough or damaged spots. The quicker you find out about issues with the wheels, the quicker you can sort the problem out.
Keep Them Smooth
Stainless steel casters are resistant to corrosion, but they will rust if not correctly lubricated when it’s time. It is ideal to lubricate stainless steel casters at least once in six months to keep them smoothly rolling in motion. You must also lubricate the wheels immediately if you feel that the movement is less smooth or if the wheel has started to tug.
Check The Fastenings
Don’t just examine the wheel for wear; also check the fasteners. If the fastener wears away or loosens, the wheel will get compromised, and there might be some damage to the equipment it is carrying. Therefore remember to check the fasteners for wear and fix anything that needs attention.
Repair And Replace As Necessary
Always remember to repair anything that needs attention immediately. Letting damage to the wheels build up over time will compromise their integrity and cause wheel failure quickly.
Do not try to work with faulty and damaged wheels. If the caster has become damaged beyond repair, you should replace it as quickly as possible since not doing so can compromise the transit process and damage the equipment. Ideally, you should also know the lifespan of the wheel you have so you can prepare for replacements once the time is over.
Stainless steel casters are widely used in the market everywhere. These wheels are strong and incredibly durable, making them best for harsh environments. Stainless steel casters are also long-lasting, so they can go years without being compromised. Talk to the manufacturer before investing in the wheel, so you know what grade is best for your line of work.
