System having robotic workstation
An apparatus is disclosed including a robotic system having a robotic picking workstation, tote storage and retrieval and transit decks. The system has bots that autonomously transport totes from the storage and retrieval system to the robotic picking workstation via the transit decks. The robotic picking workstation may have a picking lane where a robotic handler transports eaches from totes on the bots to order totes in the workstation. The robotic picking workstation further has a queuing buffer where bots are cued for the picking lane.
