Process layout
This automation solution utilizes Mech-Mind 3D Vision and the Hyundai YS140 industrial robot to automatically sort and stack boxes onto pallets by size, as well as transfer them to conveyors.
By employing two sets of highly cost-effective 3D vision sensors, the system can stably perform both palletizing and depalletizing tasks even when various product boxes are mixed together (Mixed-Case Palletizing). The project was implemented to improve worker health and safety by automating tasks known to cause musculoskeletal disorders.

Workflow
| STEP 1. | Palletizing Recognition: Two 3D cameras simultaneously identify the shape and location of boxes on the conveyor while searching for available stacking space on the pallet. |
|---|---|
| STEP 2. | Stacking: The robot picks the recognized box using a vacuum gripper and unloads it into the optimal remaining space on the pallet based on box dimensions. |
| STEP 3. | Depalletizing Recognition: The overhead 3D vision identifies the shapes and coordinates of boxes currently stacked on the pallet. |
| STEP 4. | Unloading: The robot picks the identified boxes and unloads them onto the discharge conveyor. |
Features
Unbeatable Vision Value & Performance
Cost-Efficient Dual-Vision: Even with a two-camera setup for simultaneous palletizing and depalletizing, the 3D vision solution remains highly affordable, priced in the late 40 million KRW range.
Deep Learning Recognition: Exceptional accuracy in identifying diverse objects using AI-based 3D vision.
Robust in Challenging Environments: Maintains high recognition rates even for dark-colored products or surfaces with high light reflection, such as packaging tape.
High-Density Detection: Successfully distinguishes individual boxes even when they are tightly packed with minimal gaps.
Intelligent Motion Planning: Easily performs collision avoidance and high-density stacking (compatible with most major robot brands).
Wide Field of View: Capable of recognizing a wide area, enabling tasks on pallets with stacking heights exceeding 2 meters.
Results
| Key Benefits | Significant reduction in personnel required for manual box loading and unloading.
Improved workplace safety by automating high-risk ergonomic tasks.

|---|---|
| Client Feedback | Automating robotic depalletizing was previously difficult to implement in mass production due to the limitations of 2D vision and varying product specs. However, through ROAS's affordable and accurate solution, we achieved a successful deployment. For palletizing, where workers often had to restack boxes multiple times to achieve high density, the robot now performs the task to a very satisfying standard. |

Recommended Solution
Position and Orientation Compensation using Hyundai HH7 and Conveyor Tracking
This logistics automation solution utilizes the Hyundai HH7 robot, the HRVision 3D vision system, and conveyor tracking technology to automate the manual task of recognizing text on boxes and aligning them according to the text orientation. By leveraging the high-speed processing of HRVision, the system can identify product images while in motion. Combined with conveyor tracking, the robot can pick and align moving objects without stopping the belt, ensuring a seamless and highly efficient workflow.
Beverage Pallet Unwrapping Solution using Three Hyundai HS220 Robots
This industrial robot solution utilizes three Hyundai HS220 robots to automate the hazardous task of manually removing stretch wrap and straps from beverage pallets. Previously, this process posed a significant risk of safety accidents because workers had to use manual cutters on pallets with high stacking heights. Although the complexity of the task made automation difficult in the past, Hyundai Robotics' specialized solution has made it possible. Additionally, the system neatly manages residual waste, minimizing the need for operator intervention and management.
Powder Compaction Press Assistance using Doosan M1013
This automation solution utilizes the Doosan M1013 collaborative robot to automatically load and stack powder-compacted cutting tool components onto pallets. This system is characterized by its rapid teaching capabilities and high workplace safety. The powder compaction process traditionally generates significant amounts of dust, creating a hazardous environment for human workers. By implementing robot automation, idle time has been minimized to allow for continuous operation. Furthermore, a 100% inspection process has been integrated into the workflow, successfully reducing the overall defect rate.
