Stacker-Bot Autonomous Mobile Robot and Automated Storage and Retrieval System (ASRS)


The Stacker‐Bot can store and retrieve on a single trip up to five cases or totes. The AMR automatically picks a case or tote, scans the barcode and stores it in the Stacker‐Bot on any one of the five onboard shelves. It then uses its RCS (Robot Control System) and communicates to the WMS/WCS host software system.

Once the inventory has been retrieved, the Stacker‐Bot is directed via the WMS/WES software host to place the inventory in exact locations. The rack, shelf level and shelf location for each of the five SKUs is communicated to the Stacker‐Bot. The robot always travels via the shortest path to its location.

AMR Applications:

Inventory transportation to and from:

  • Flow Rack 
  • Rack 
  • Workstations
  • Automated Equipment
  • Conveyor

After the AMR has picked up its product to be replenished, the Stacker‐Bot uses its two dimensional camera technology to find its first location. It verifies its position by scanning the bar code on the rack and shelf level. Then, it automatically places the tote or case in the proper SKU location. This operation is done transparently from the picking operator located at the front of the flow rack.

The Stacker‐Bot travels to its next location and repeats this process until its load is depleted. It then goes back to the re‐loading station to pick up more SKUs and repeats the process.

The number of Stacker‐Bots required for a system is based on the throughput, capacity and floor space requirements.
