How do goods-to-person picking systems work to bring inventory directly to a stationary picker?

We ask the same underlying question in different ways.

• How do goods-to-person picking systems work to bring inventory directly to a stationary picker?
• Can you explain the mechanism behind goods-to-person picking and how it delivers items to a fixed station?
• I'm looking to understand how automated workflows function when they bring inventory to a stationary picker for fulfillment. How does that work?
