3D Cube Storage Systems
3D Cube Storage
Attabotics 3D Cube Storage System
1. System classification and architecture
System type: three dimensional cube automated storage and retrieval system (ASRS); goods-to-person order fulfilment.
- Structure: self supporting vertical grid (“cube”) storing bins in a dense three dimensional array.
- Robotics: a fleet of robots (Attabots) traverses the grid in all three axes — across the top, down the sides and through the interior.
- Access model: every robot can reach every bin and every presentation station; each bin is directly accessible with no digging or re slotting.
- Sequencing and sortation: performed within the structure, in the volume beneath the storage array (the “basement”), removing the need for external conveyor systems.
- Presentation: stations are located on the perimeter and integrated into the structure geometry, so any robot can serve any station.
- Redundancy: no single point of failure at robot level — a robot fault does not isolate stored inventory or a zone.
2. Robot (Attabot) specifications
Parameter | Specification |
Travel | All three axes of the grid (horizontal, vertical and across the top) |
Access | Every bin and every presentation station |
Top speed | 8.8 ft/s (approx. 2.68 m/s) |
Maximum payload | 99 lb including bin weight (approx. 45 kg) |
Power source | Long life ultra capacitors |
Charging | Recharged each cycle while climbing (no battery swap or dedicated charging downtime) |
3. Storage structure and density
Parameter | Specification |
Maximum build height | Up to approx. 40 ft (approx. 12.2 m) — see note on height figures |
Footprint reduction | Up to 85% versus a manual pick from shelf layout |
Bin retrieval time | Bin delivered to a presentation station within approx. 90 seconds of request |
Slotting requirement | Performance independent of order structure; no fast-mover zone or Pareto curve required |
Storage density | Class leading; every bin remains directly accessible despite high density |
4. Throughput and presentation stations
Parameter | Specification |
Rate per station (current) | More than 300 bins per hour to the operator |
Rate per station (newer stations) | 400 to 500 bins per hour |
Station placement | Anywhere on the perimeter; integrated into the structure geometry |
Throughput scaling | Increased by adding robots and presentation stations, without expanding the building footprint |
5. Bin specifications
Two bin heights are available; both accept removable dividers for up to 16 compartments per bin.
Parameter | Medium bin | Tall bin |
Outer dimensions (l x w x h) | 24 x 24 x 11 in | 24 x 24 x 17 in |
Interior dimensions (l x w x h) | 22 x 22 x 10 in | 22 x 22 x 16 in |
Empty weight | Approx. 9.7 lb (approx. 4.4 kg) | Approx. 9.7 lb (approx. 4.4 kg) |
Maximum payload | 99 lb incl. bin (approx. 45 kg) | 99 lb incl. bin (approx. 45 kg) |
Material | Polypropylene, UNIPOL 2135 | Polypropylene, UNIPOL 2135 |
Dividers | Up to 16 compartments | Up to 16 compartments |
6. Performance metrics
Metric | Figure |
Space reduction | Up to 85% (versus manual pick from shelf) |
Labour reduction | Up to 75% |
Capital expenditure reduction | Up to 50% |
Bin accessibility | 100% (every robot reaches every bin) |
Robot count vs competing approaches | Approx. 25% fewer robots |
7. Deployment envelope and scalability
- Installed range: from fewer than 5,000 bins to more than 190,000 bins per system.
- Modular scaling: storage capacity and throughput scale independently — add bins to extend storage, add robots and stations to raise throughput.
- Expansion impact: the system can be extended without significant disruption to ongoing operations.
- Deployed sectors: luxury retail, general and B2B retail, ecommerce beauty, automotive, food service and general merchandise (North America).
8. Industries where Automated Storage Systems can be used
- No external conveyor systems required; sequencing and sortation are internal to the structure.
- Automatic sequencing of orders, including small orders requiring a set pack order.
- Retrieval performance is independent of assortment profile, so no slotting optimisation is required to sustain it.
- Ultra capacitor charging on each cycle avoids battery swap stations and associated downtime.
- Robot level redundancy provides fault tolerance without loss of access to stored inventory.
Benefits of Automation
for forward-thinking companies
When robots and automation are implemented in a business effectively, they don’t replace jobs. They augment them to drive greater productivity.
