If you’re a robot builder, a maintenance technician, or someone who relies on functional, well-made robot parts to keep operations running smoothly, you already know that even the highest quality components can fail prematurely if stored incorrectly. As a robot parts supplier who has worked with industrial automation teams, hobbyists, and research labs for over a decade, I’ve seen firsthand how a simple storage misstep—like leaving a servo motor exposed to fluctuating humidity or stacking circuit boards on top of heavy metal frames—can turn a $50 precision encoder into dead scrap overnight. Today, I’m pulling back the curtain on how our team stores every part that leaves our warehouse, and sharing the science-backed practices we’ve refined over years to help you protect your investments, avoid costly delays, and extend the lifespan of your robot components. Robot Parts
First, let’s start with the basics: every robot part has unique material properties and sensitivity thresholds that demand tailored storage solutions. Not all parts are the same, so a one-size-fits-all approach is a recipe for disaster. Let’s break down the most common robot parts and how to store them correctly, starting with the parts that make up the core of any robot: servo motors, stepper motors, and gearboxes. Most of these are made of a mix of high-grade steel, aluminum, copper windings, and plastic insulators. The biggest threats to these parts are moisture, dust, and physical impact. Copper windings are particularly prone to corrosion if exposed to high humidity, and dust can get into gearbox gears, causing grinding and wear that leads to motor failure down the line.
At our warehouse, we store all unassembled motors and gearboxes in sealed, moisture-barrier plastic bags with a small desiccant packet inside. The desiccant absorbs any residual moisture in the air that gets trapped when sealing, and the barrier bag prevents outside humidity from seeping in during long-term storage. We also add a corrosion inhibitor tag to each motor’s bag—these tags release a mild, non-toxic vapor that prevents rust and oxidation on steel and copper components, even in spaces with slightly higher humidity. For short-term storage (under 30 days), we keep motor units in rigid plastic bins lined with anti-static foam, which prevents scratches and absorbs minor impacts if a bin is knocked over. The key here is never to store loose motors on shelves where they can roll or be stacked with heavy items; we once learned this lesson the hard way when a forklift operator dropped a 5kg metal frame on a bin of stepper motors, cracking their housings and rendering 12 units unfit for sale. Now, all motor storage is on dedicated, slotted shelves designed to hold one motor per slot, so there’s no risk of shifting or impact.
Next up: circuit boards, microcontrollers, and electronic control modules. These are the most sensitive parts in any robot, not just because they’re expensive, but because even a tiny static discharge (ESD) can fry a microchip or erase firmware without leaving any visible damage. I’ve had customers send back circuit boards that “stopped working” after 6 months of storage, only to tell us they were stored in a cardboard box in a garage—garages are death for electronics, with fluctuating temperature, high humidity, and no ESD protection. Static is invisible and can build up on surfaces as small as a single grain of dust, so proper ESD storage is non-negotiable. Our team stores all unassembled circuit boards in static-shielding bags, which are made of a special material that dissipates static charge instead of letting it build up. We never use regular plastic bags for electronics, and we never stack circuit boards directly on top of each other—even a thin layer of plastic between boards can create static that damages components. For bulk storage, we use ESD-safe drawers with individual slots for each board, so they don’t touch each other. We also keep our electronics storage area at a consistent 20-22°C (68-72°F) and 40-50% relative humidity, per standards set by the Institute of Electrical and Electronics Engineers (IEEE). Fluctuations in temperature and humidity cause expansion and contraction of board materials, leading to solder joint cracking over time—something we see all too often when customers store electronics in unconditioned spaces.
Then there are structural robot parts: aluminum extrusion, custom brackets, and metal frames. These are the “bones” of the robot, designed to hold all other components in place, but they’re not immune to damage. The biggest risks here are corrosion (if they’re not coated), scratches that can lead to rust, and warping from uneven weight distribution during storage. Many people make the mistake of leaning aluminum extrusion against a wall or stacking metal frames haphazardly, but aluminum is soft enough to scratch easily, and uncoated steel frames will rust if exposed to moisture. At our warehouse, we have dedicated vertical racks for structural parts, with slots sized to hold standard 20mm, 30mm, and 40mm aluminum extrusion lengths. This keeps extrusion from bending or getting scratched, and it saves floor space too. For custom brackets and metal frames, we use individual foam inserts in plastic crates, custom-cut to fit each part’s shape. We also apply a light layer of food-grade rust inhibitor to all uncoated metal structural parts before storage—this leaves no sticky residue that can transfer to other parts during assembly, and it’s safe to wipe off with isopropyl alcohol when the customer is ready to use them. We avoid stacking heavy parts on top of lighter ones, of course, but we also make sure that structural parts are not stored near any volatile chemicals or cleaning supplies that could leave corrosive fumes on their surfaces.
Another often-overlooked category is sensors: LiDAR modules, proximity sensors, camera modules, and force-torque sensors. These parts are full of delicate lenses, optical components, and small circuit boards, so they’re sensitive to both physical impact and environmental factors. LiDAR lenses, for example, can get scratched by even a tiny particle of dust, which reduces their accuracy and range permanently. Camera modules have similar issues, and proximity sensors can be damaged by moisture that seeps into their housing. At our warehouse, we store all sensors in their original packaging whenever possible—original manufacturer packaging is designed to protect them during shipping and storage, with custom foam inserts that hold the sensor in place and prevent the lens or housing from moving. For sensors that are removed from their original packaging, we use sealed plastic cases lined with anti-scratch foam, and we never open a sensor’s protective seal until it’s ready to be installed into a robot. We also keep sensors in dark storage areas when not in use, because prolonged exposure to direct sunlight can fade lens coatings and degrade the sensor’s internal electronics. We once had a customer return a batch of new LiDAR sensors claiming they were inaccurate, only to find out they had been stored on a windowsill in his workshop for three months—UV exposure had damaged the internal lens coating, a problem that could have been avoided by simply storing them in a dark, closed cabinet.
Beyond part-specific storage practices, there are universal rules that apply to every robot component, no matter what type it is. The first is inventory organization. We use a strict first-in, first-out (FIFO) system for all storage areas, which means that the oldest parts are used or shipped first, instead of sitting on a shelf for years. Parts like batteries, for example, have a finite shelf life—lithium-ion batteries, common in mobile robots, can lose up to 20% of their capacity per year if stored incorrectly, especially at full charge. We store batteries at a 40-50% charge, in cool, dry areas, and we track every battery’s manufacture date and charge level to ensure they’re used before their shelf life expires. Another universal rule is labeling. Every bin, shelf, and bag in our warehouse has a clear label with the part number, manufacture date, and storage requirements, so our team never has to guess how to store a specific part. For customers who order parts in bulk, we include detailed storage instructions with every shipment, tailored to each part they ordered—no generic advice, just specific steps for their components.
Temperature and humidity control are also universal non-negotiables. Even if you’re storing parts in a small home workshop, you don’t need a full climate-controlled warehouse—just a closed cabinet or closet that stays at a consistent temperature, away from windows and heating vents. Avoid storing parts in garages, basements, or attics, where temperatures can swing dramatically from hot to cold, and humidity can spike with seasonal changes. A good rule of thumb is to aim for a temperature between 15-25°C (59-77°F) and humidity between 30-60%, which is ideal for almost all robot components. For extra protection, you can add a small, low-cost hygrometer to your storage area to track humidity levels, and a desiccant packet in each bin of parts to absorb excess moisture.
We also recommend regular inspections, even for parts that are in storage. Every 90 days, our team checks stored parts to make sure desiccant packets are still effective, bags are still sealed, and no parts show signs of corrosion, damage, or dust buildup. For bulk orders that a customer plans to store for long periods (over 6 months), we recommend doing a quick functional test on a sample of parts to catch any issues before they’re needed for assembly. This simple step has saved countless customers from scrambling to find replacement parts right before a deadline—something every robot builder knows is one of the worst pains in the industry.
At the end of the day, storing robot parts correctly isn’t just about keeping them organized—it’s about protecting the investment you’ve made in your robot projects, reducing downtime, and ensuring that when you’re ready to build or repair, your parts work as well as the day they were manufactured. For over a decade, we’ve refined these practices to make sure every part we supply arrives in perfect condition, and we want to help you do the same for your components.
