Reticulated Foams Expand The Boundaries Of Cellular Solids

Ideally suited for high-tech applications, reticulated foams of ceramic or metal provide industry as well as the research community with an extraordinarily versatile material form that can be engineered for particular properties and tailored for specific applications. The interconnected lattice of continuous ligaments within the cellular structure provides greater strength than shorter fibers and also ensures uniform material characteristics throughout the structure.

Tension Stiffened and Tendon Actuated Manipulator

This configuration offers mechanical advantage and improved efficiency over existing arms that use weighty gearboxes and motors. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center is developing a robotic arm with lightweight joints that provide a wide range of motion. The envisioned design provides users with a long reach and numerous degrees of freedom. The arm, ideal for use in aquatic environments or for manipulation of light terrestrial loads, consists of articulating booms connected by antagonistic cable tension elements. The arm elements are structurally efficient and lightweight, and support compact packaging. The inherent mechanical advantage provided by the tendon articulation allows the use of small, efficient motor systems. The manipulator can be scaled over a large range from 10 m (load-bearing arm) to over 1000 m (submersible or float-supported arm). Current efforts are focusing on a 15-m prototype and a 300-m subsystem to test the unique robotic architecture. NASA is seeking partners to assist with the development of its concept system for specific applications.
