Boston Dynamics Rates Stretch Gen 2 at 1,000 Cases an Hour, a Peak With Three Conditions Attached

Boston Dynamics rates the second generation of its Stretch trailer-unloading robot at up to 1,000 cases per hour, according to The Robot Report's account of the launch dated November 6, 2026. The company's own product page for Stretch, which does not yet mention Gen 2, describes the first generation as moving "hundreds of cases an hour".

The 1,000 figure is a ceiling, and the company says so: the actual rate depends on case weight and how neatly boxes are stacked. Automation magazine's write-up of the launch, dated November 5, adds a third condition, carton integrity. All figures here are vendor-supplied; no independent party is named as having measured them.

What changed from Gen 1 in the hardware

Most of the announcement is about maintenance, not speed. Gen 2 took about two and a half years, per The Robot Report, which quotes Brian Donnelly, vice president and general manager of logistics robotics at Boston Dynamics. The changes read like a list of things that broke in the field.

Item	Gen 2 figure (vendor-supplied)	Source
Peak unload rate	1,000 cases per hour	Robot Report, Automation
Battery	Two shifts per pack	Robot Report, Automation
Fast charge	90% in about 75 minutes	Robot Report, Automation
Internal cabling	81% less, about half a mile removed	Robot Report, Automation
Swerve drive swap	About 1 hour, previously a full working day	Robot Report, Automation

Boston Dynamics replaced them with automotive-grade connectors, and Robot Report says Hyundai helped source a cable harness through its automotive supply chain.

A drive module swap that takes about an hour instead of a full working day turns a lost shift into a lost hour, and standardized fasteners plus onboard diagnostics let a customer's own maintenance team do routine service.

The 100,000-hour denominator

Boston Dynamics says Gen 2 draws on more than 100,000 operating hours and tens of millions of boxes handled by first-generation units. That is the only fleet-scale number in the launch, and it invites arithmetic. A hundred thousand hours is 11.4 years of one robot running without a break. Even at the top of "tens of millions", 99 million boxes over 100,000 hours is under 1,000 an hour, so the fleet's average sits below the new peak by a margin the company has not given.

The number that matters here is the gap between peak and average, because a trailer is not a uniform wall of identical cartons. The new multipick feature is the lever. Boston Dynamics' multipick post says Stretch can pick up to four boxes at once, decides in real time how many to grasp from box size and face alignment, and drops to single picks when a large box needs every suction cup.

Robot Report adds one more figure: software ships roughly monthly, and the latest update raised fleet unload rate by 24%.

What the launch leaves out

The product page lists a 50-pound case limit for Stretch; Robot Report gives no payload for Gen 2. No source gives a price, which the product page replaces with a contact-sales link. No source gives a count of robots deployed. Robot Report says Gen 2 is running at multiple customer sites and that installing it at an existing site takes about two weeks, against the product page's "days from delivery" for the older model, and it names none of them.

The product page shows logos for Otto Group, NFI, Gap, Arvato, DHL, Maersk and H&M; nothing links them to Gen 2 units. A buyer comparing Stretch with Dexterity, Pickle Robot or Mujin, the rivals Automation magazine's editors list, has a peak rate and a repair time but no throughput measured on a customer's freight.

Unloading is a cost-per-case argument, as with delivery robots in Serve Robotics' third-quarter numbers and industrial robots in China's block of SoftBank's ABB Robotics purchase: unit count and utilisation decide it.

What would change my read

A named customer reporting cases per hour over a full quarter would settle it. If that average came in near 600, the Gen 2 story is uptime; if it came near 900, the multipick claim is real. Until a customer says which, 1,000 is a specification and not a result.
