How a Top Retailer Simplified Inbound Automation with Intelligent Robotics by Mujin

Employing the MujinController platform to master depalletizing and overcome complex mixed-SKU challenges

When a major retailer engaged Mujin to automate a mission-critical distribution center (DC), they encountered a significant challenge: automating mixed-SKU depalletizing. Known for its complexity due to the unpredictable nature of workpieces, this task had long been deemed too challenging for automation. The retailer’s DC, which managed a vast array of products varying in shape, size, and weight, struggled with manual depalletizing operations that were not only slow but also prone to errors and physically taxing on the workforce. 

Mujin’s objective was to overturn this long-held belief by developing a scalable automation solution that could handle the complexity of mixed-SKU depalletizing while achieving industry-leading picking rates and reducing error rates. Leveraging advanced vision systems, tactile feedback, and the MujinController platform, we set out to transform their operations by enhancing accuracy, throughput, and overall operational efficiency.

Identifying the Challenge

The distribution center was responsible for managing a diverse inventory of products. Manual handling slowed down operations and introduced errors while placing significant physical demands on the workforce. The need for a robust, automated solution was clear. However, the complexity of mixed-SKU depalletizing presented a challenge that had eluded automation providers for years. 

Crafting the Solution

Our approach began with a detailed design phase, where our engineers collaborated closely with the retailer’s team to ensure seamless integration with their existing workflows. This phase was crucial for addressing the complexity of mixed-SKU depalletizing and ensuring that the automation solution could handle the diverse range of products managed by the distribution center. 

The solution centered around cutting-edge mixed-SKU depalletizing robot cells, each equipped with the following: 

Advanced Robots

MujinController-powered robots offer real-time motion planning and precise torque control, preventing collisions and minimizing downtime. Their sensor-rich grippers provide tactile feedback for handling products of varying sizes, ensuring precision, versatility, and high throughput in picking operations.

Cutting-Edge Vision Systems

Mujin vision systems are capable of 3D scanning for precise product identification and handling. They include sophisticated pipeline verification of sensor results and advanced groupings of detection, enabling opportunistic multi-picking and ensuring accurate and efficient processing of a wide range of SKUs. 

Automated Guided Vehicles (AGVs)

AGVs streamline pallet transportation within the facility, coordinated by the MujinController platform to eliminate system starvation. The use of AGVs reduces the costs associated with traditional conveyor systems while maintaining continuous flow and high efficiency. 

Overcoming Obstacles

The implementation of robotic automation for mixed-SKU depalletizing was not without its challenges. The variability in pallet loads—often containing items with irregular shapes, difficult-to-grip surfaces, and a wide range of sizes—posed a significant hurdle. These complexities have traditionally made mixed-SKU depalletizing difficult to automate, requiring a solution that could maintain both speed and accuracy despite these variables. 

To address this, Mujin integrated advanced robotic grippers capable of handling a broad spectrum of products. These grippers, powered by the MujinController platform, provided precise control and real-time feedback, allowing the system to adapt dynamically to the unique characteristics of each item. The ability to generate dynamic workpiece physics models in real time was crucial in achieving high levels of picking accuracy, even with challenging materials.

The MujinController platform’s real-time digital twin was pivotal in navigating these complexities. By creating a live, virtual representation of the physical environment, the platform enabled continuous monitoring and adjustment of the robot’s actions. This dynamic model ensured that the system could respond effectively to irregular and complex pallet loads, maintaining optimal performance and accuracy. Additionally, the digital twin provided a comprehensive data environment that facilitated ongoing refinement and optimization of the system.

Another challenge was the need to upgrade the distribution center’s operations without causing significant disruption. Given the critical role of this facility in the retailer’s supply chain, minimizing downtime was essential. Mujin’s team meticulously planned the installation process, coordinating work during off-peak hours to ensure that the distribution center could continue its operations with minimal interruption. This strategic approach allowed for the seamless integration of the new system, demonstrating Mujin’s commitment to both innovation and operational continuity. 

By leveraging the capabilities of the MujinController platform and a strategic approach to system integration, Mujin successfully overcame these obstacles. The result was a robust automation solution that met the retailer’s needs and set a new standard for efficiency, accuracy, and reliability in mixed-SKU depalletizing. 

Seamless Implementation

The successful deployment of Mujin’s automation solution required a meticulous approach to ensure that every phase of the project was executed flawlessly. From the initial concept to the final go-live, each step was carefully planned and coordinated to deliver a seamless integration with the retailer’s existing operations. The focus was not just on installing advanced technology but on ensuring that this technology enhanced the overall efficiency and reliability of the distribution center without disrupting its critical daily operations. 

Mujin’s implementation process was comprehensive, encompassing all major project phases: 

  • Pre-sales Concepting and Solution Identification: The journey began with close collaboration with the retailer, identifying the specific needs and challenges of their distribution center. This phase involved rich, obsessive customer collaboration to ensure that the proposed solution was not only feasible but also aligned with the retailer’s operational goals. 

  • Detailed Engineering Design: Mujin’s engineers developed a detailed layout and specification for each subsystem, focusing on precision and integration. This phase included the sizing and specification of each component to ensure optimal performance and seamless operation within the existing infrastructure.
