Square Structural Joint with Robotic Assembly Tool

NASA Langley Research Center developed a square structural joint design that enables robotic assembly and has been designed for high strength-to-weight, multifunctionality, and reduced manufacturing cost. The joint not only provides increased axial stiffness compared to round tubes of the same width but torsional and bending strength is increased as well. Electrical conductivity and provisions for routing of wiring or tubing through the joints have been incorporated in the design, all enabling greater capability and a stronger structural design.
