Rackbot Systems: Autonomous Solutions for Efficient Picking

Autonomous Mobile Robots (AMRs) in combination with flexible shelving systems

With our RackBot Systems, SSI SCHAEFER makes the first steps towards semi-automated logistics processes easier – not just for small and medium-sized companies. They offer a wide range of use cases – “Plug & Play” makes them simple and inexpensive.

The suitable high-performance solution packages help you to optimize your storage, transport and picking processes in order to achieve long-term success.

The holistic solution package designed by SSI SCHAEFER combines the advantages of SSI SCHAEFER rack systems and RackBots from the SSI Mobile Robots range. The result is picking systems that can be implemented quickly and offer autonomous storage and retrieval of goods in different bins. This means that RackBot Systems can be ideally integrated into existing replenishment and picking processes.

All RackBot Systems have one thing in common: They significantly reduce the time required for picking and order processing. They can also be installed quickly in existing warehouses, are easily scalable at any time and reduce logistics costs in the long term.

RackBot System Elevate: Vertical and horizontal bot roaming in high-density racking systems

RackBot System Elevate expands the existing RackBot portfolio with a new generation of autonomous mobile robots (AMRs): the so-called ClimbBots. Thanks to their innovative mobility concept, these robots can move both horizontally and vertically, climbing up and down shelving units. This creates a freely moving robot swarm in where each vehicle can independently access any storage location and container within the racking system.

As with all RackBot systems, the ClimbBots' control is fully integrated into the warehouse's order management system. This enables intelligent sequencing of all picking processes—reducing the time between order creation and container delivery to under two minutes. Depending on the warehouse structure and item profile, up to 4,000 containers per hour per 1,000 m² of storage space can be transported.

Scalable Warehouse Robotics with High Fault Tolerance

The ClimbBots operate as an intelligent, fully decentralized swarm. If one bot fails, others take over its tasks—without any interruption in operations. This architecture ensures maximum system availability and minimizes risks in critical processes.

Thanks to its modular structure and high scalability, RackBot System Elevate supports a wide range of applications—from compact shelving warehouses with a few thousand containers to large-scale systems with over 300,000 storage locations.

Flexible. Efficient. Future-Proof.

RackBot System Elevate is designed to meet diverse logistical challenges and is suitable both for entry into semi-automated order picking and for expanding existing facilities. Customers benefit from the following features:

• Maximum Storage Density: Up to 12 m rack height, narrow aisles starting at 900 mm, and no need for cross-traffic pathways

• High-Performance Picking: 200 – 800 containers per hour per picking station, tailored to individual needs

• Free Bot Roaming: Every ClimbBot can access every position in the system—no fixed zones required

• Flexible Integration: Supports both B2B and B2C processes, batch and single-item picking, and various order management strategies

• Easy Commissioning: No rack coding needed, immediate operational readiness, intuitive operation, standardized components

• Economically Scalable: Modular system design, ROI often under 12 months, reusable system components

RackBot System Compact: plenty of storage in limited space

RackBot System Compact is a very dense and flexible storage solution that has been specially developed for applications with high throughput and fast order processing. It optimizes the use of space through vertical storage with up to 43 bins per square meter and enables fast access to fast-moving items. With the fast RunBots (AMRs) in combination with RackBots, the Autonomous Mobile Case-Handling Robots (ACRs), the system ensures fast response times and optimized storage processes, ideal for requirements with a consistently high turnover of goods.

RackBot System Compact uses two robot technologies for maximum efficiency and fast picking. The RackBots reach up to 12 meters in height and are responsible for the strategic handling of bins within the warehouse. The RunBots operate in parallel and ensure the rapid provision of priority orders at a speed of up to 4 meters per second. The bins are linked together so that the storage space can be used optimally and fast-moving items are available quickly. Integration into existing warehouse management systems facilitates smooth operation.

Advantages of RackBot System Compact:

• Extremely dense storage: Up to 43 bins per square meter, ideal for maximum use of space.

• Fast access to priority items: RunBots can reach a speed of 4 meters per second.

• Cost reduction: Savings in labor costs through elimination of walking distances.

• Precise picking: Batch picking of up to 9 bins per run with over 99.9% accuracy.

• Triple-deep storage is possible using the linked bins.

• Round-the-clock operation: 24/7 use and simple integration into existing systems for consistently high availability.

RackBot System Eco: The efficient storage of containers and cartons

RackBot System Eco is a versatile and scalable “goods-to-person” solution designed for high efficiency and flexibility in warehouse operations. The automated storage and provision system increases storage density and order throughput while significantly reducing labor costs. Using autonomous ACR technology (Autonomous Case-Handling Mobile Robots), the system guarantees high picking accuracy and integrates seamlessly into existing warehouse management systems.

The modular RackBot System Eco consists of autonomous mobile robots, the RackBots, which navigate through strategic warehouse areas and reach heights of up to 12 meters. The RackBots transport up to 9 bins simultaneously to the picking station, which increases efficiency enormously. In addition to the integration of the mobile robots, the system comprises inbound and outbound work stations, flexible rack options and centralized control. It is suitable for different loading units such as cartons and bins and can handle many different dimensions.

RackBot System Eco is equipped with rack systems from SSI SCHAEFER that are individually tailored to your needs. The quality and robust construction not only allows a long service life, but also easy adaptation to changing conditions.

Advantages of the RackBot System Eco:

• Maximum storage density: Vertical storage up to 12 meters enables optimum use of space.

• Fast order processing: Up to three times the processing speed for efficient handling.

• Cost savings: Lower labor costs thanks to the elimination of travel times and transport of up to 9 bins simultaneously.

• Round-the-clock operation: 24/7 availability and smooth integration into existing systems.

RackBot System Flex: more flexibility through additional pallet storage

RackBot System Flex extends the functions of the RackBot System Eco and also enables the storage and automated picking of bulk goods and mixed items. It is ideal for the efficient handling of mixed picking processes and is suitable for a wide variety of items, including small, medium and large, loose or irregular products. RackBot System Flex considerably increases efficiency in warehouse operations, reduces storage space requirements and retains all the benefits of flexibility and scalability of RackBot Systems.

RackBot System Flex uses two robot technologies to optimize various storage operations: The RackBots (ACRs) move in vertical areas up to 12 meters high and enable precise warehouse management of individual bins. At the same time, the TransferBots (AMRs) handle the picking of bulk goods and palletized goods. This combination enables the efficient handling of different types of stored goods. The system also comprises inbound/outbound work stations, industrial racks, software for centralized control and supports any bin shape or even storage without bins.
