# DHL Supply Chain: Boston Dynamics Stretch robotic case unloading

That people must spend entire shifts lifting loose-loaded cases from hot or cold trailers.

Function: Logistics. Patterns: Exception-based operations. Evidence: reported.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 2 primary; publication outcomes are reported.

## Before

1. **Warehouse associate** — Enter the trailer, identify each case, lift it, and place it onto a conveyor. (control: Manual pace and safe-lifting practice)
2. **Warehouse team** — Clear fallen or irregular cases and sustain throughput across the shift. (control: Human coordination)

## After

1. **Stretch robot** — Uses perception and a robotic arm to identify, grasp, and place cases from the trailer onto a conveyor. (control: Robotic operating envelope)
2. **Warehouse associate** — Supervises the cell, clears exceptions, and works in downstream or higher-value tasks. (control: Human safety and exception authority)

## Decision rights

The robot selects routine grasp and placement actions; people control cell safety and exception recovery.

## Exception path

Humans handle fallen boxes, unsupported products, jams, and cases outside the robot's grasp envelope.

## Outcomes

- **Case unloading rate** (reported): Manual unloading rate in tested environments → Up to 700 cases per hour; DHL states tested robot speeds exceeded the manual approach. Operator-reported maximum, not an average; product mix affects speed and employee-satisfaction improvement was not quantified.

## Executive lesson

The case is strongest as an ergonomic workflow redesign; throughput is a maximum, and the undisclosed exception rate determines labor economics.

## Anti-pattern

Using the 700-case maximum as an average or ignoring exception labor.

## Questions for leaders

- What is sustained throughput by product mix?
- How often does a person enter the cell?
