Streamlining Your Workflow: Material Handling and Logistics
Getting the right part to the right place at the right time is the lifeblood of any factory. Collaborative robot applications in material handling remove bottlenecks and keep production flowing smoothly.
Material Handling
Material handling is a broad category that covers moving parts and materials within a facility. This includes transferring items between conveyors, sorting products, and feeding machines. Historically, handling operations have been the largest application for industrial robots worldwide. They act as the mechanical muscle of the factory, lifting heavy components or moving goods 24/7 without fatigue.
Pick and Place
Pick and place is exactly what it sounds like: picking up an object and putting it somewhere else. It’s one of the most common collaborative robot applications, prized for its speed and accuracy. High speed delta robots, for example, can perform up to 200 picks per minute, sorting and packing small items on a production line. This boosts throughput dramatically while freeing humans from mind numbing repetition.
Bin Picking
Random bin picking has long been called a “holy grail” of robotics. It involves a robot identifying and grasping jumbled parts from a container, a task that requires advanced 3D vision and AI. While challenging, modern systems are making it a reality on factory floors. This technology is automating one of the last major manual handling tasks, allowing robots to feed parts directly from bulk storage into machines.
Machine Tending
Machine tending involves loading raw materials into a machine (like a CNC or injection molding machine) and unloading finished parts. It’s a dull, repetitive, and often unsafe job that is difficult to staff. Robots are the perfect solution, keeping machines running at full capacity around the clock without breaks or ergonomic strain. In fact, machine tending is now the largest application of collaborative robots, a testament to its effectiveness. See examples of advanced automation in manufacturing facilities.
End of Line Excellence: Packaging and Palletizing Applications
Once a product is made, it needs to be packaged and prepared for shipment. These end of line collaborative robot applications ensure goods are sent out quickly, correctly, and safely.
Packaging
Robotic packaging systems handle everything from wrapping and boxing to labeling products for sale. They are incredibly fast and uniform, using different types of robots for specific tasks. For instance, delta robots can pick and place lightweight food items into trays, while other robots can neatly pack boxes for shipment. This level of automation helps companies meet tight deadlines and high consumer demand.
Food and Beverage Packaging
In the food and beverage industry, hygiene is everything. Robots used for these packaging applications are specially designed with washdown ready surfaces and food grade materials to prevent contamination. They handle tasks like sorting produce, bottling drinks, and packing meat with minimal human contact, enhancing food safety. The adoption of these robots surged by 56% in North American food companies in 2020 as businesses sought to maintain output during the pandemic.
Pharmaceutical Packaging and Handling
Similar to the food industry, pharmaceutical packaging requires absolute precision and sterility.

Achieving the Perfect Finish: Surface Treatment and Material Removal
The final look and feel of a product often comes down to its finish. These collaborative robot applications deliver flawless surfaces with a consistency that is difficult to achieve by hand.
Finishing
Finishing is a broad term for processes that refine a product’s surface, such as grinding, sanding, and polishing. Robots excel here because they can apply steady pressure and follow exact paths every time. A robotic finishing system can often match or even surpass the quality of a skilled human artisan, all while working faster and longer.
Material Removal
Material removal involves cutting away excess material from a workpiece using processes like drilling, milling, or routing. Robots offer incredible flexibility, as they can be programmed to cut complex shapes on large or awkwardly shaped parts. This is especially useful in the aerospace and automotive industries for trimming composite panels or plastic components with precision.
Deburring
After a part is machined, it often has small, sharp fragments called burrs along its edges. Robotic deburring uses specialized tools to remove these imperfections, ensuring part quality and safety. Unlike manual deburring, which can vary, a robot applies the same pressure and motion every cycle for a perfectly uniform edge finish.
Sanding
Manual sanding is dusty, tedious, and physically demanding. Robotic sanding automates this chore, producing a consistently smooth surface every time. A manufacturer of wooden shutters improved their production time by over 80% after implementing a robotic sander. Better yet, robotic systems with vacuum attachments can capture up to 95% of sanding dust, creating a much cleaner and safer work environment.
Polishing
Polishing is used to create a smooth, shiny surface on materials like metal or plastic. Robotic polishing systems use force controlled arms to mimic the gentle, consistent motions of a skilled polisher. They can produce a uniform, mirror like finish that is free of the inconsistencies that can arise from human fatigue.
Precision Dispensing: Adhesives and Sealing
Many products rely on adhesives or sealants to hold them together or protect them from the elements. Robotic dispensing ensures these materials are applied perfectly every time.
Adhesive Dispensing
Automated adhesive dispensing involves the precise application of glues. Robots lay down a consistent bead or droplet of adhesive to join parts, resulting in less waste and stronger bonds than manual gluing. In automotive manufacturing, robots apply a uniform bead of adhesive to windshields, ensuring a perfect seal.
Sealing
Sealing is a specific type of dispensing focused on creating a barrier against moisture, air, or dust. Robots apply sealants to car bodies, window frames, and electronics enclosures with high precision. This guarantees a continuous, even bead that prevents leaks and improves product durability and reliability.
Specialized Collaborative Robot Applications for High Tech Industries
Beyond the traditional factory floor, collaborative robots are making a significant impact in labs and quality control departments, where precision is not just preferred, it’s required.
