Stretch, the latest innovation from Boston Dynamics, represents a significant evolution in robotic technology, specifically designed for warehouse operations. Unlike its predecessors, Stretch is purpose-built for efficiently moving cases in a warehouse environment. Its unique morphology includes a mobile base with a versatile drive system, a turntable housing the robot’s arm, perception mast, and vacuum system. Notably, Stretch stands out for its ability to understand the environment and autonomously make decisions, adapting to real-world challenges dynamically.
What sets Stretch apart is its focus on closed-loop control, constantly learning from its surroundings and reacting in real-time. Unlike pre-planned trajectories, Stretch’s awareness of its state and the surrounding world allows it to navigate and perform tasks efficiently, making it well-suited for the dynamic nature of warehouse operations. The development of Stretch was a response to market demand, initially inspired by the application of Atlas in warehouses. However, realizing the need for a more purpose-built and streamlined solution, Boston Dynamics shifted its focus to create Stretch, combining the best of wheels and legs for optimum maneuverability in warehouse spaces.
The evolution from earlier prototypes like Handle to the refined design of Stretch involved a deep understanding of warehouse requirements. Stretch incorporates a 7-degree of freedom arm, a perception mast with individually actuated sensors, and a mobile base for versatile movement. Continuous learning and improvement through data analysis, machine learning, and deep learning contribute to Stretch’s adaptability and efficiency in various warehouse scenarios. The product version of Stretch includes enhancements such as a quieter vacuum pump, a dedicated safety system, and a smart gripper for handling damaged boxes. As Stretch continues to operate in real-world environments, it exemplifies Boston Dynamics’ commitment to creating robots that address practical challenges and contribute to increased productivity in industries like warehousing.
