Mobile robot for truck and container unloading
More from Boston DynamicsBoston Dynamics unveiled the current generation as Stretch Gen 2 on 2026-11-03. The maker reports unloading up to 1000 cases per hour, depending on case weight and stacking, with multipick enabling peak rates. It states that the battery lasts two shifts and reaches 90 percent charge in about 75 minutes with a fast charger. The redesign includes automotive-grade connectors, an upgraded gripper with new valves and more precise sensing, continuous-rotation joints beyond 360°, 81 percent less internal cabling, a lower recessed emergency stop, revised exterior panels, onboard diagnostics and redesigned onboard computing with regular software updates. Boston Dynamics says a swerve-drive swap takes about one hour instead of a full day. Onboard lighting and a pre-trained vision system support unloading in dark trailers. The product page lists cases up to 50 pounds. Boston Dynamics says the redesign draws on more than 100,000 operating hours and tens of millions of boxes unloaded by first-generation deployments.
