The RobotStackr OTF

Smarter Mixed Palletizing
with AI in Real-Time

RobotStackr OTF calculates 3D stacking positions and robot motion paths on the fly — from any box to any carrier, instantly.

The challenge

Robotic integrators face growing demands:

  • Improve automation business cases for logistic handlers, while increasing the added value of automation solutions.

  • Deliver faster, more flexible solutions.

  • Reduce engineering time and custom logic.

  • Avoid bulky systems like buffer sequencers.

  • Enable end-users to stack mixed items reliably.

  • Keep projects efficient, compact, and scalable.

The RobotStackr OTF advantage

RobotStackr OTF helps you deliver smarter mixed stacking systems — faster.

  • AI-optimized stacking for mixed-size products — no pre-sorting or buffers needed.

  • Sub-second response time with integrated robot motion paths.

  • Easy IPC integration, compatible with all major robot brands, gripper types and hardware setups.

  • Expert integration support for optimal end-customer process integration. We actively help you to improve the end-customer’s businesscase.

  • Better results for your clients: higher throughput on a lower footprint, less manual labor and more stable loads.

Use Cases

Do you need to stack pallets with boxes of a wide range of sizes? Viroteq’s RobotStackr offers a solution for mixed-SKU stacking to optimize the number of boxes on each pallet whilst considering
complex practical constraints, such as the stability of the stack.

Whether it concerns bins, containers, or ULDs, the Viroteq RobotStackr can take into account carrier limits and shapes to perform optimal packaging actions in every situation. This makes it possible for, for example, 3PL distribution and sorting centers to efficiently carry out the stacking and packaging processes with a range of specifications.

We can accommodate a wide range of postal carts of different sizes to meet specific logistics needs, with optimized volume efficiency to maximize your freight capacity. Through stability calculations, we carefully consider the physical constraints of postal carts, ensuring your goods are delivered safely and in pristine condition.

Reliable Performance

The RobotStackr ensures stable and efficient palletizing without the need for time-consuming SKU programming. The user-friendly system is designed for maximum productivity, allowing operators to work effortlessly without complex training. With advanced monitoring and real-time reporting, you maintain full control over your logistics processes, preventing unexpected disruptions.

Smart technology that adapts automatically

The RobotStackr is equipped with AI-driven optimization, enabling the system to learn in real-time and dynamically adjust to your workflow. It continuously analyzes and optimizes to ensure the most efficient and stable stacking solutions.

Full process control

With the Viroteq RobotStackr, you retain complete control over your palletizing process thanks to integrated quality control and data-driven decision-making. Seamless data exchange with your WMS optimizes processes and provides full visibility into the status of your production and logistics operations. This results in fewer errors, higher accuracy, and a more efficient workflow.

For any logistics challenge

The Viroteq RobotStackr can be easily integrated into your existing WMS infrastructure without complex installation procedures. The system determines the optimal stacking pattern on the fly and can minimize pre-sorting steps when needed. Whether your business is expanding or requires flexibility for different product formats, the RobotStackr scales effortlessly to meet changing demands.

Multi-Carrier stacking flexibility

The Viroteq RobotStackr is not limited to pallet stacking—it is designed to handle a variety of carriers, including pallets, roll cages, bins, and more. This flexibility allows businesses to adapt their logistics processes to different transportation and storage needs, ensuring seamless automation across various workflows. Whether stacking for warehouse storage, retail distribution, or specialized transport, the RobotStackr provides efficient and reliable handling for multiple carrier types.

StackrBrain Technology

The Viroteq RobotStackr is our all-in-one solution for automating mixed-SKU stacking processes from start to end. The StackrScan system determines the dimensions of incoming boxes, and using our state-of-the-art AI StackrBrain technology, we find the most optimal stacking position for improved volumetric efficiency. The AI model is trained on millions of stacks, enabling it to outperform human stacking ability. Our solution also considers physical constraints, such as the stability of the stack and the feasibility of the robot for reaching the placement position, making it perfectly suitable for deployment in real-world logistics.
