Boston Dynamics Stretch Timeline

Boston Dynamics launched an upgraded version of Stretch in January 2025. The update improved handling throughput, broadened the range of package types the system could process reliably, and reduced handling errors by approximately 40% compared to prior deployments. Pilot testing across three large US distribution centres showed a 20% increase in daily order processing capacity without additional headcount. The robot was reported to have outperformed human workers in both speed and accuracy in controlled comparisons.

DHL Supply Chain signed a Memorandum of Understanding with Boston Dynamics committing to deploy more than 1,000 Stretch robots across its logistics network by 2030. By this point the robot had already been deployed in DHL facilities in North America, the United Kingdom, and Europe. DHL reported live unloading rates of up to 700 cases per hour in operational conditions — below the peak specification but consistent across extended shifts.

DHL Supply Chain achieved the first commercial deployment of Stretch, becoming the first company to put the robot to work in live logistics operations. The initial application was truck and container unloading — one of the most physically demanding and difficult-to-automate tasks in a warehouse. DHL had announced its partnership and initial $15 million investment in Boston Dynamics in January 2022; the production units reached the facilities approximately 18 months later.

DHL Supply Chain announced a $15 million investment in Boston Dynamics and signed on as the first commercial customer for Stretch. The announcement confirmed the commercial trajectory for a robot that had until that point been demonstrated only in controlled environments. Otto Group separately announced plans to deploy Stretch across more than 20 facilities — adding a second anchor customer to the product's commercial pipeline.

Boston Dynamics unveiled Stretch in March 2021, presenting it as a purpose-built commercial product rather than a research or demonstration platform. The announcement positioned Stretch as the practical, task-focused counterpart to Boston Dynamics' other robots: where Atlas explored the limits of dynamic movement and Spot offered a general-purpose mobile platform, Stretch was designed to do one thing commercially — move boxes.

Boston Dynamics acquired Kinema Systems, a Bay Area startup specialising in vision-based robotic picking for warehouses. Kinema's Pick system — which uses 3D sensors and machine learning to identify, locate, and grasp packages of varying sizes and orientations — became the vision foundation for Stretch. The acquisition gave Boston Dynamics a critical software capability it would need to make Stretch commercially viable without building it from scratch.

Boston Dynamics began developing what would become Stretch in 2018, working in collaboration with DHL Supply Chain to understand the practical requirements of warehouse automation. The partnership gave Boston Dynamics direct access to real logistics environments and the specific constraints — package diversity, trailer geometry, throughput requirements — that any viable warehouse robot would need to handle. DHL's input shaped the product's design priorities from the outset.
