Technical description
The DELIE automatic picking system uses 4-way tote-shuttle robots to bring containers to the workstations in a goods-to-person scheme. The operator does not move: the system delivers the correct tote at the exact moment. This eliminates picking travel (which accounts for 60% to 70% of the time in manual operations) and allows reaching 800 to 1,200 lines/hour per station, with error rates below 0.1%. Ideal for e-commerce operations with high volumes of few-unit orders.
How it works
High-density grid storage
Totes are stored in a high-density three-dimensional grid. Shuttle robots operate on a grid of horizontal rails at the top of the system, going down to fetch totes with a vertical lifting mechanism integrated into the robot itself.
Goods-to-person delivery
When the WMS generates an order, the WCS calculates the optimal route for each needed tote. The robot retrieves the tote and delivers it to the operator's workstation. Multiple robots operate simultaneously, ensuring a continuous flow of totes with no waiting time.
Order consolidation
The operator at the station receives the tote, extracts the units indicated by the pick-to-light system or screen, and confirms the operation. The order is consolidated at the station and goes to packing. The system optimizes the tote delivery order to minimize time between confirmations.

DELIE technology in Argentina
DELIE — official STOKA representation
The DELIE picking system requires no floor QR codes or vision cameras for navigation: it uses a rail grid that guarantees precise positioning with no periodic calibration. This reduces maintenance costs and downtime vs. vision-based AMR systems.
DELIE has more than 1,000 active installations in over 30 countries. STOKA is the exclusive representative in Argentina: engineering, installation and local technical support without depending on overseas factory lead times. World-class technology at a price for the LATAM market. More about DELIE in Argentina →
Frequently asked questions
Frequently asked questions
How many orders per hour can a DELIE picking system dispatch?
A 4-picking-station system with a 100-robot fleet can dispatch between 3,000 and 5,000 orders/hour of 1 to 3 units each. For larger orders (5–10 units), throughput is 1,200 to 2,000 orders/hour. STOKA simulates the exact throughput for your warehouse's order profile before the proposal.
What happens if a robot fails during operation?
The WCS redistributes the failed robot's load among the available fleet without interrupting the operation. The defective robot is removed manually (it weighs less than 25 kg) and replaced without tools. The fleet can operate with up to 20% of robots out of service without critical throughput degradation.
How many SKUs can the picking system manage?
The limit is the physical space of the grid. With 10,000 tote positions and 2 SKUs per tote on average, the system manages 20,000 active SKUs. The software allows storing multiple totes of the same SKU in different positions to balance the robots' load.
Can automatic picking be combined with manual picking for low-rotation SKUs?
Yes. The usual architecture in e-commerce warehouses is: automatic picking (goods-to-person) for 80% of the volume (zone A), manual picking on conventional racking for the remaining 20% (zones B and C). The WMS consolidates both flows at the packing station.
