RackBot

Store more totes within your available footprint and retrieve the right inventory when the operation needs it. Valor integrates Rainbow Dynamics’ RackBot into modular goods-to-person solutions designed around your SKU profile, peak throughput and financial targets.

RackBot makes use of warehouse height instead of relying entirely on long manual picking aisles. Single-deep and double-deep storage configurations offer different balances between density and accessibility. The optimal arrangement is determined by SKU velocity, tote movements, replenishment frequency and retrieval demand — not by density alone.

→ Single-deep storage

One tote is stored at each rack depth position. This provides direct access to the stored tote and can suit operations where frequent access and responsive retrieval are priorities.

→ Double-deep storage

Two-deep positions increase storage density within a given footprint. Valor assesses the effects on access strategy, stock allocation and throughput before recommending a configuration.

Rainbow Dynamics specifies a maximum operating height of up to 8.5 metres, tote fetch times as low as 3 seconds and up to 150 tote movements per RackBot per hour. These are supplier-stated maximum or indicative figures, not a guarantee of site-wide throughput. Achievable performance depends on rack design, travel distances, tote allocation, robot fleet, workstations and system scheduling.

The platform supports tote payloads up to 30 kg and can be engineered around standard shelving configurations, subject to project-specific assessment. System dimensions, operating conditions and performance should be confirmed against the selected robot configuration and final engineering specification.

The robot is only one part of the throughput equation. GroundBot provides horizontal tote transport to the workstation; ergonomic workstations and visual picking guidance support the operator; and conveyor interfaces can route completed totes towards consolidation, packing or dispatch. Valor designs these interactions together to prevent bottlenecks shifting from one process to the next.

→ An engineering partner with wider warehouse expertise

Valor has established its expertise in person-to-goods automation through modular conveyors, sortation, software and controls. The addition of RackBot extends our capabilities into goods-to-person storage while keeping one consistent approach to operational design.

→ Shared focus on functionality and simplicity

We chose Rainbow Dynamics because its modular robotics and straightforward design principles complement our Qliqflow philosophy. The aim is dependable performance and an understandable solution, rather than excessive customisation or unnecessary technical complexity.

→ An investment sized to the requirement

Valor starts with the actual storage and retrieval requirement. We model the number of locations, robots, workstations and associated transport capacity needed now, alongside realistic expansion stages. This approach prioritises a compelling initial business case and a strong, sustainable ROI.

→ Integration from picking to dispatch

Where appropriate, we integrate RackBot and GroundBot with Qliqflow conveyor modules, warehouse controls and upstream or downstream equipment. That allows the entire material flow to be designed and supported as a coordinated system.

RackBot is worth evaluating in tote-based environments with large SKU assortments, costly picker travel, constrained storage space and demanding order profiles. We will also assess whether a different storage or picking approach is more appropriate for heavy, oversized or unusually fast-moving products.
