Frequently Asked Questions Grid


What does SDG and DDG mean?

This refers to the rail tracks for the Robot wheels found along the top of the Grid.

SDG stands for Single/Double Grid. This design provides a single rail track along one axis and a double rail track along the other axis. Utilizing a single rail in one direction requires the Robots to have a cell between them when passing.

DDG stands for Double/Double Grid. This design provides a double rail track in all directions allowing Robots to pass each other in all directions.

What is the center-to-center distance (length-width) between the Bins?

Single/Double Grid: 705mm (27.8 inches) in wide Grid direction and 480mm (18.9 inches) in narrow Grid direction.

Double/Double Grid: 705mm (27.8 inches) in wide grid direction and 505mm (19.9 inches) in narrow Grid direction.

Are there any limits to the size of the Grid?

Max height is 16 of the 330 mm Bins or 24 of the 220 mm Bins resulting in 5.4 m (17.75 feet). With Robots and recommended service space, the height is 7.52 m (24.67 feet) in total.

The max height for the 425 mm Bins is 14 high of the 425 mm resulting in 6 m (19.6 feet). With Robots and recommended service space, the height is 8.18 m (26.84 feet) in total.

What is the minimum height required for the Grid?

This depends on the design. At the very least, the minimum height must be as the following plus the Grid track above it:

  • 220 mm Bin: 6 Bins
  • 330 mm Bin: 4 Bins
  • 425 mm Bin: 3 Bins

This Bin depth provides the needed height for a Port.

Less space is needed if the track is used "only" as a road for transporting Bins between different Grids. In this case, the design can either be a track with no Bins or a track with at least one Bin plus the track above.

How much space do we need between the roof and the top of the Grid?

For Robot trafficking we need 600 mm (2 feet) for R5 and 860 mm (2.8 feet) for B1.

It needs to be possible for service and support staff to operate and use the AutoStore service vehicle on the grid. The recommendation from AutoStore is at least 2 m (6.5 feet) of open space above the Grid. In special cases a lower height could be accepted by the local authorities, but this needs to be clarified and approved by the local authorities and the local AutoStore distributor.

What is the total clearance between the Bin length and width dimension versus the opening created by the Grid (length and width)?

3 mm (0.1 inch) on all sides (Bin tolerance +/-2 mm)

Will SDG still be available?

Yes, although DDG will be the new standard going forward.‍

Is it possible to have AutoStore Grids installed on different floor levels in the building?

Yes. Bin Lift Grid-to-Grid (G2G) configuration allows Bins to flow between Grids on different floor levels.

Bin Lift is currently only available in the EU, United States, Canada, Japan, Korea, China, Israel, Panama, Serbia, and Uruguay.

We are working on adding more countries with the applicable product approvals. Note that it may take longer in some countries to get approval.

Can I install a self-supporting AutoStore Grid?

Yes, it is possible to install a self-supporting AutoStore Grid using Grid Bracers. The Grid Bracer provides operational support to the AutoStore system and eliminates the need for additional structural construction around the pillars or walls, allowing you to utilize your available storage space to its full potential. In addition, the use of a Grid Bracer can significantly shorten the installation lead time and lower the cost of the AutoStore system.

Note that the Grid Bracer is only compatible with the Double/Double Grid.

Can an AutoStore Grid be installed in an environment with temperature variations?

In environments with temperature variations, it is vital to consider temperature effects on the Grid aluminum tracks, especially for large Grids. AutoStore Grid component, Flexible Grid Cell, gives large Grids high resilience and holds the tracks together while safely absorbing thermal expansion. This maintains the Grid evenness and ensures optimal working conditions for the Robots – a key parameter for system stability and uptime.
