Voodoo Robotics’ Pick-to-Light system can be used one of TWO WAYS.
Single Lighted Picking Scenario
A simple way to use the system is as a destination device so that each time an item is picked from stock, a put light on the cart illuminates to show in which tote that item should be placed.
Double Lighted Picking Scenario
In a double-lighted system, each pick and each put can BOTH be acknowledged by devices. In this scenario, as the picker pushes the picking cart down the aisle, Pick-to-Light devices (usually attached to a rack) associated with a picklist illuminate, then after each pick, a put light on the cart illuminates to show in which tote the inventory should be placed.
Picking carts optimize batch picking by reducing the pickers total travel distance while increasing his/her accuracy and picking rates.
