Mobile Warehouse Box-Handling Robot

Stretch

Stretch revolutionizes warehouse and logistics automation by automating the physically demanding and injury-prone task of unloading trucks and containers. Unlike traditional warehouse robots, Stretch is purpose-built for the material handling environment with an omnidirectional mobile base, a long-reach seven-degree-of-freedom arm, and an intelligent adaptive gripper that handles a wide variety of box types and sizes. The robot can unload hundreds of cases per hour from trailers while safely navigating tight warehouse aisles, adapting its grip strength based on real-time sensor feedback, and using advanced vision to identify and place boxes with precision.

Frequently Asked Questions

Stretch automates high-volume, physically demanding truck unloading work that causes repetitive strain injuries and worker fatigue. The robot unloads cases at consistent rates all day long, improving both safety and predictable throughput for logistics operations.

No. Stretch is designed to operate within standard warehouse and trailer geometries. It can work with existing racking, conveyor systems, and workflow layouts, making deployment straightforward and avoiding costly facility modifications.

Stretch uses 3D vision on its independently articulated perception mast to detect box edges, corners, and surfaces in real-time. The adaptive gripper applies force sensing to adjust suction strength dynamically, enabling it to handle plain cardboard, printed boxes, and cases of varying sizes without pre-programming.

Yes. Stretch is designed to work with a broad mix of box types, sizes, and weights. Its vision system and planning algorithms adapt on the fly, so no special setup or configuration is needed when shifting between different product types.

Stretch is designed to operate for approximately two full shifts (≈16 hours) on a single charge, depending on box weights, cycle times, and travel distances. This enables continuous operation across typical warehouse shifts.

Yes. Stretch is mobile and can be moved between truck bays, container docks, and other unloading stations. This flexibility allows warehouses to share one robot across multiple loading points or to concentrate Stretch where unloading demand is highest.
