New 'Soft' Robot: Shape-Changing and Versatile
Researchers from Stanford and UC Santa Barbara have created a novel robot that blends traditional and soft robotics. This human-scale pneumatic robot can change shape and move independently once inflated, without needing a constant power or air source. Unlike conventional robots with heavy, energy-intensive linear actuators, this design is lightweight, flexible, and durable. Its structure consists of inflatable tubes forming a adaptable truss that can reshape by relocating its joints.
This innovation combines the strengths of soft, collective, and truss-based robots while addressing their individual limitations. The result is a robot that's safe around humans and versatile in various environments. It's particularly suited for space exploration and search-and-rescue missions, as it can compress for transport and expand when deployed. The robot's ability to change shape allows it to navigate difficult terrain effectively.
This development represents a significant step towards more practical and adaptable robots for real-world applications.
