Problem Statement
Client wanted to automate the manual task of an operator collecting the items from a warehouse and separating it for an order as per the desired SKUs. This was being done to reduce any errors that they were seeing in the manual process.
Technical Solution
AxoNet team came up with a solution to digitize the entire process by creating custom controllers that would be placed near each sorting station. The orders will be received by an Embedded Linux controller that will notify each Display Controller about the quantity that is to be filled in at that station. That count will show up on the screen which will be used by the operator to populate the container with that SKU count.
