Global e-commerce return rates average 15–25% of orders. In European fashion markets, that number climbs to 50%. In U.S. apparel, 60%. In the U.S. alone, retailers process hundreds of billions of dollars in returned merchandise each year. Each of those items requires individual handling: physical inspection, condition grading, and a disposition decision made under uncertainty about the item's state, completeness, and resale potential.
Despite this scale, returns handling remains one of the least automated workflows in modern warehousing. Unlike inbound logistics or order fulfillment, where item states are predictable and tasks are well-defined, returns arrive in variable condition, require multi-step inspection sequences, and demand conditional decision-making that changes with every item. These properties have made the workflow resistant to conventional automation approaches, and most facilities continue to rely almost entirely on manual labor.
At high throughput, human graders show significant inter-rater variability in condition assessment: one operator's “resalable” is another's “refurbish,” and consistency degrades further across shifts and sites. But labor inconsistency is a secondary problem. The primary one is structural: there is no scalable, automated solution for a workflow that handles hundreds of millions of different items per year. That gap is what returns automation is built to close.

Returns handling has long been one of retail's most labor-intensive workflows, and one of the least optimized. Each item requires individual handling, physical inspection, condition grading, and a routing decision. At scale, the per-item cost of that process frequently approaches or outright exceeds the item's remaining resale value.
This is why many retailers have historically treated returns as a write-off. Not because they lacked the capability to assess returned goods, but because the economics didn't justify the effort. Discarding items was often cheaper than processing them.
That approach is no longer viable. Return volumes have grown to the point where the inbound flow alone creates significant bottlenecks in warehouse operations. Across Europe and the U.S., logistics providers are now dedicating entire facilities exclusively to returns handling.
What makes returns particularly resistant to automation is the nature of the task itself. Unlike conventional pick-and-place operations, which involve moving a known item from a defined location to another, returns handling is a multi-step decision workflow operating under continuous uncertainty. Every item is different and their conditions vary. Packaging is damaged, missing, or misleading. The correct action at each step depends on what was learned in the steps before it.
No single subtask is the bottleneck. The challenge is managing the full sequence reliably, at speed, across an unpredictable stream of items.
Lower Costs
Per-item handling cost drops, making detailed inspection viable again
Consistency
Same criteria applied to every item, every shift, every site
Safety
Reduces human exposure to sharp objects, contaminated or unknown items
Value Recovery
Items that would be discarded can be assessed for resale or recycling
From the moment a customer ships an item back to the point where it's restocked, refurbished, or discarded, the item passes through a sequence of tightly coupled steps. Each one introduces its own complexity, and each one depends on the decisions made before it.
At every stage, the robot isn't just executing; it's deciding. Reshelve, refurbish, or discard? Is this item actually unused, or just cleverly repackaged? Should it attempt a different viewing angle before committing to a grade?
These are sequential decisions under uncertainty, and getting them right has a direct impact on the bottom line.
Returns handling demands a type of manipulation that single-arm systems simply can't deliver. Opening packages, unfolding garments, and inspecting items all require both arms working in coordination. These tasks can't be broken down into sequential single-arm steps without either adding fixture support or fundamentally redesigning the workflow.
This is what separates returns handling from conventional pick-and-place automation, where a single end-effector operates on predictable, geometrically constrained objects. Returns introduce deformable materials, unknown object states, and contact-rich manipulation sequences that need continuous force distributed across two arms.
Manipulation skills developed in simpler settings carry over as reusable building blocks in more complex bimanual tasks: grasp stability, contact-aware motion planning, dynamic object tracking all transfer. As the complexity of tasks grows, learned capabilities stack rather than requiring the system to start over.
Handovers & Coordination
One arm extracts the item from a bin while the other stabilizes surrounding objects. One arm holds an item in position while the other inspects, scans, or reorients it. Coordinated handovers between grippers enable smooth multi-step sequences.
Reorientation
Returned items rarely arrive in a convenient pose. Dual arms can flip, tilt, and rotate objects to expose hidden labels, inspect undersides, or position items for scanning.
Bag & Deformable Handling
Polybags, tissue paper, flexible packaging. Deformable materials are everywhere in returns. One arm holds the bag taut while the other extracts or inserts the item. Single-arm systems struggle with materials that change shape under contact.
Natural Skill Progression
Knowledge from single-arm pick-and-place transfers directly: grasp planning, object detection, and motion control all carry over. Dual-arm extends these foundations into coordinated manipulation.
The Lens system is our visual intelligence layer, suitable for the inspection and classification demands of returns handling. Where Cortex controls what the robot does, Lens determines what the robot knows about each item: its condition, its category, and what should happen to it next.

Critically, Lens doesn't operate in isolation. It works directly with Cortex's manipulation policies. If a visual inspection is inconclusive because a label is partially occluded or an item is folded in a way that hides a defect, Cortex can actively reposition the item to give Lens a better view. The robot doesn't just look at what's in front of it; it manipulates the scene to gather the information it needs.

This tight coupling between perception and action is what makes the system work. Lens turns what the robot sees into a decision, and Cortex turns that decision into physical execution.
Returns handling is the kind of problem Cortex 2.0 is well-suited for: long-horizon, high-uncertainty, and deeply tied to real-world variation that no controlled environment can fully replicate.
Proactive Planning
Cortex doesn't wait for things to go wrong. Its world model anticipates outcomes by learning that certain grasps on deformed boxes tend to fail, that reorientation before inspection leads to better results. It plans ahead instead of reacting after the fact.
Learns From Production
Every return processed in a live warehouse teaches the system something new. Damaged packaging, unusual items, edge cases that would be nearly impossible to simulate, all arise naturally at scale. Cortex turns that operational data into better policies.
Full-Trajectory Learning
Rather than learning only from success or failure, Cortex extracts signal from every step: partial progress, near misses, unstable states, recoveries. In long-horizon returns tasks, this makes learning dramatically more efficient.

The result is a system that improves with every shift, learning from the full complexity of real-world returns rather than simplified lab setups or hand-crafted rules.
Returns handling represents a class of manipulation where success depends on reasoning across extended sequences. Objects arrive in unpredictable conditions, requiring inspection, physical interaction, and conditional decision-making as execution progresses.
Solving it well establishes a foundation for more complex domains like kitting, assembly, and manufacturing, where environmental diversity and physical constraints intensify but the need for sustained reasoning remains the same.
Returns handling marks a critical transition: from robots that excel at single-step tasks to systems that understand and manage processes. Cortex 2.0 is designed for exactly that shift.

Open-world autonomy
E-commerce return rates average 15–25% across general retail, reaching up to 60% in fashion. The volume of returned goods now exceeds what manual processing can absorb at acceptable unit economics.
Cortex 2.0 addresses this directly. Returns handling is a long-horizon decision workflow where each step depends on the outcome of the last, and item state is unknown until physically examined. Cortex 2.0 reasons trough possible futures, adapting at each step based on what it observes. Condition assessment of items via Lens feeds structured classification signals directly into routing decisions, with active reorientation when views are inconclusive.
Importantly, the system improves with deployment. Every item it processes is a real training signal drawn from actual warehouse returns, not a simulated environment. Performance improves continuously, without anyone needing to update rules or trigger retraining cycles.
