Warehouse deployments of collaborative robots increased tenfold between 2018 and 2025, according to data cited by Kassow Robots, a Denmark-based manufacturer of seven-axis cobots. The figure underscores a fundamental shift in how distribution centers approach automation: rather than hard-coding fixed workflows around heavy industrial robots, operators now favor mobile systems that combine autonomous mobile robots with lightweight cobots capable of redeploying across multiple tasks within a single shift. Kassow pointed to the compact form factor of modern cobots as the primary enabler, allowing integrators to mount articulated arms on AMR platforms without compromising payload capacity or battery life. The company manufactures cobots ranging from 5 kg to 18 kg payload capacity, with reach extending to 1800 mm on its largest model.
The architecture matters because warehouses no longer operate on predictable cycles. E-commerce fulfillment centers routinely see demand spikes that triple pick rates within hours, then drop to baseline just as quickly. Fixed automation struggles with this variability. A six-axis industrial robot bolted to a concrete pad excels at repetitive tasks but becomes a liability when demand shifts to a different product category or storage zone. Mobile cobot systems sidestep the problem entirely. An AMR equipped with a compact cobot can pick apparel in the morning, shift to electronics assembly in the afternoon, and handle returns processing by evening. Kassow noted that its seven-axis design provides an additional degree of freedom compared to traditional six-axis arms, enabling the robot to reach around obstacles or into confined spaces without repositioning the mobile base. That capability proves critical in facilities where racking layouts change quarterly or even monthly to accommodate seasonal inventory.
Several factors converged to drive the 10x growth curve. Cobot prices dropped significantly between 2018 and 2024, with entry-level models now available for under $25,000 compared to $50,000 or more seven years ago. Battery technology improved in parallel, allowing AMR platforms to support the power draw of a cobot arm for full eight-hour shifts without mid-shift recharging. Safety certifications also matured during this period. Collaborative robots operate without safety cages, but early models required conservative speed limits and force thresholds that hampered productivity. Current-generation cobots from Kassow and competitors now feature torque sensors in every joint, enabling them to detect collisions within milliseconds and halt motion before force exceeds safe thresholds. That responsiveness allows cobots to work at speeds approaching traditional industrial robots while maintaining the flexibility to operate alongside human workers. Warehouses capitalized on the improved economics and performance by deploying AMR-cobot systems in applications that previously required either manual labor or custom automation: kitting, quality inspection, machine tending, and bin picking among them.
The integration complexity should not be understated. Mounting a cobot on a mobile platform introduces challenges that do not exist in fixed installations. Vibration and acceleration forces from AMR movement can degrade cobot accuracy, particularly during high-speed navigation or emergency stops. Communication latency between the AMR controller and cobot controller can cause synchronization errors, leading to dropped objects or failed picks. Kassow addressed the vibration issue through mechanical isolation mounts and software compensation algorithms that adjust arm trajectories in real time based on IMU data from the mobile base. The communication challenge requires tighter integration between AMR and cobot software stacks, with some vendors opting for unified controllers that manage both the mobile platform and manipulator through a single interface. Battery management adds another layer of complexity, as the cobot arm typically draws 200 to 500 watts under load while the AMR platform itself consumes 300 to 800 watts depending on speed and payload. Integrators must size battery packs to support combined peak loads while keeping total system weight within safe limits for the AMR drivetrain.
Industry observers point to the warehouse automation market as a proving ground for broader mobile manipulation trends. Applications that succeed in distribution centers often migrate to manufacturing, retail, and healthcare within 18 to 24 months. Mobile cobots already appear in small-batch manufacturing environments where production volumes do not justify fixed automation. Retail stockroom applications are emerging, with mobile cobots handling shelf replenishment and inventory audits. Healthcare facilities have piloted mobile cobots for material transport and specimen handling, though regulatory barriers remain higher than in industrial settings. The common thread across these applications is variability. Facilities that require automation to adapt to changing layouts, product mixes, or workflows increasingly favor mobile cobot systems over traditional fixed solutions. Kassow and competitors including Universal Robots, Techman Robot, and Doosan Robotics have all introduced compact models optimized for mobile integration, with weights under 25 kg and power consumption below 400 watts to simplify AMR pairing.
What to Watch: Kassow Robots plans to showcase its latest seven-axis cobot models at the International Conference on Robotics and Automation in Atlanta in September 2026, with particular focus on mobile integration accessories and software toolkits. Universal Robots is expected to release battery-optimized firmware updates for its UR3e and UR5e models by the end of Q3 2026, specifically targeting AMR applications. Watch for announcements from major AMR vendors including Mobile Industrial Robots and Locus Robotics regarding native cobot integration partnerships, as both companies have hinted at tighter hardware-software coupling in their 2026 roadmaps. Battery technology providers such as Forsee Power and Flux Power are developing modular packs designed specifically for combined AMR-cobot loads, with first commercial releases expected before year-end.
