Key Benefits of ACR and CTU in Warehouse Automation
Compared to manual methods or conventional automated systems, ACR and CTU bring significant advantages to enterprises:
- Boost operational efficiency: Handle multiple cases simultaneously, enabling picking speeds 3–4 times faster than manual operations.
- Reduce errors, improve accuracy: Automated systems lower the picking error rate to just 0.1%, ensuring near-perfect order accuracy.
- Optimize warehouse space: Storage height of up to 4.5 meters and 2.3 times higher density than traditional warehouses save valuable floor space.
- Lower labor costs: Reduce the need for large numbers of warehouse workers in complex environments, cutting long-term expenses.
- Fast deployment: ACR and CTU systems can be implemented in less than one month, allowing businesses to start operations quickly.
- Flexible scalability: Easily expand by adding more robots as needed, from just a few units to hundreds.

ACR & CTU Robots – Automated Case Handling and Smart Carton Transfer
- ACR (Autonomous Case-handling Robot) combines autonomous mobile robots (AMR) with a mechanism to pick cases from static shelves. Based on the Goods-to-Person (GTP) principle, robots automatically retrieve cases and deliver them to workstations or packing stations.
- CTU (Carton Transfer Unit) is a specialized AGV designed to transport cartons inside warehouses. With the ability to operate in narrow aisles and multi-level environments, CTU is an optimal solution for high-density storage.

Thanks to intelligent path planning, collision avoidance, and multi-case handling, ACR and CTU robots help:
- Increase throughput up to 3–4 times compared to manual labor.
- Reduce unnecessary travel time within the warehouse.
- Optimize workflows and minimize human errors.
- Handle large volumes of orders in short timeframes.
- Minimize product damage through precise and safe operations.
- Meet the needs of fully automated, modern warehouse models.

Real-World Applications of ACR and CTU
These technologies have been successfully applied across diverse industries:
- E-commerce & Retail: Fast and accurate order fulfillment to meet rising customer expectations.
- Distribution Centers: Manage large volumes and a wide variety of SKUs efficiently.
- Electronics Manufacturing: Precisely store and supply components to production lines.
- Healthcare: Manage pharmaceuticals and medical supplies with high safety and accuracy requirements.

The application of ACR and CTU robots in automated warehouses provides businesses with a comprehensive solution to optimize workflows, enhance productivity, and reduce long-term costs. With rapid deployment, flexible scalability, and seamless integration, ACR and CTU are becoming an inevitable trend in the digital transformation of logistics and manufacturing.
