TECHNOLOGY TRANSFER OPPORTUNITY: Reversible Androgynous Mechanical Fastener (TOP2-310)

NASA’s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. 

THE TECHNOLOGY:  

Researchers at NASA Ames Research Center have developed an androgynous fastener with high misalignment tolerance characteristics, which is suitable for robotic actuation. This fastener was developed in conjunction with a high-performance building-block structural system that can be robotically assembled by robust collective automated assembly into large, reconfigurable structures ranging from assembly of lunar habitats to terrestrial structures. The fastener mechanisms employ alignment principles similar to the International Berthing and Docking Mechanism (IBDM) in order to relax the positioning requirements of the assembly robots. This novel androgynous fastener provides the desired performance required for robotic assembly of the structural systems and also minimizes or eliminates the problems and disadvantages associated with conventional or traditional fasteners. 

The androgynous fastener is lightweight and facilitates assembly through simple actuation with large driver-positioning tolerance requirements. This fastener provides a high-strength, reversible mechanical connection and may be used in high strength-to-weight ratio structural systems, such as lattice structure systems. It is beneficial in any application where robotic end effectors are used to join structural components (or other parts) together. It may be particularly desirable for applications requiring frequent movement of hardware to an assembly site to replace joint connections.
