Boston Dynamics has launched [Stretch Gen 2](https://x.com/BostonDynamics/status/2117663862564573240?ref=tao.media), a redesigned version of its autonomous trailer-unloading robot that reduces internal cabling by 81% and cuts a full swerve drive replacement from a day to about an hour. The changes focus on keeping warehouse robots working longer and making them easier for customers to repair.

The redesign draws on [more than 100,000 operating hours and tens of millions of boxes unloaded](https://bostondynamics.com/news/boston-dynamics-launches-next-generation-stretch-robot/?ref=tao.media) by first-generation Stretch robots. Boston Dynamics used that deployment data to identify recurring sources of unplanned downtime, then revised the electrical systems, joints, gripper, protective panels, and maintenance architecture around those failures.

"Our customers count on Stretch to keep freight moving, and every hour a robot sits idle is an hour of work that piles up on the dock," said Brian Donnelly, vice president and general manager of logistics robotics at Boston Dynamics.

## Rebuilding Around Common Failure Points

Removing cabling is one of the largest structural changes. Boston Dynamics eliminated roughly half a mile of internal wiring, reducing what it identified as the robot's biggest source of intermittent electrical faults and wiring wear. The new design also removes dynamic cables and complex harnesses, simplifying the assemblies technicians need to work with during repairs.

Heavy-duty, automotive-grade connectors address another source of wear: vibration from rapid, high-torque box handling and travel over uneven warehouse floors. These changes target the electrical connections that must remain reliable while the robot repeatedly drives, reaches, lifts, and places freight.

The mechanical redesign includes continuous-rotation joints that can move beyond 360 degrees without hitting the hard stops that previously caused mechanical stress. An upgraded gripper adds new valve systems and more precise sensing to improve grasping and placement during fast picks.

Boston Dynamics also changed how the robot handles incidental contact with falling freight. The emergency-stop control sits lower and is recessed, while exterior panels use new materials. Together, those changes make a falling box less likely to trigger an unintended safety stop or damage a panel.

## Making Repairs Practical on the Dock

The service redesign combines modular, plug-and-play components with standardized high-strength fasteners. That reduces tool changes and hands-on repair work; the one-hour swerve drive swap is one example of the shorter service procedure.

New onboard diagnostics and maintenance tools let customers' own maintenance teams perform more routine service. This shortens repair time for warehouse operators and lets them handle more of the work locally rather than relying on outside support.

## Unloading Performance and Fleet Software

Stretch Gen 2 can unload up to 1,000 cases per hour. Boston Dynamics says that rate depends heavily on case weight and how neatly or irregularly boxes are stacked, with a multipick feature helping the robot reach peak throughput by handling multiple cases in a pick.

The battery supports two shifts of operation, and a fast charger brings it to 90% charge in about 75 minutes. Onboard lighting allows operation inside dark trailers, while a pretrained vision system detects most packages without programming before use.

The broader [Stretch platform](https://bostondynamics.com/products/stretch/?ref=tao.media) works within existing warehouse infrastructure and makes handling decisions in real time. Its unloading behaviors include detecting and retrieving boxes that shift or fall during the process, allowing work to continue without an operator intervening for each displaced package.

Gen 2 also introduces a redesigned onboard computing platform. Regular software releases improve case detection, motion planning, picking strategies, and world modeling, the robot's representation of its surroundings, across a fleet without requiring hardware changes.
