    Abstract: Rebar-based support assemblies that can be fabricated without the need for on-site welding. The assemblies include a number of differing sized and shaped crimps used in place of welds to provide rebar assembly-to-rebar assembly connections. Each crimp mechanically couples two or three pieces of rebar together, such as a border bar of one rebar assembly to a border bar of an adjacent rebar assembly. Each crimp includes a body with two or more arcuate recessed surfaces each for receiving a piece of rebar. In a first configuration of the crimp, a pair of spaced-apart arms (or extending members) extend from the body and define an opening through which the rebar is passed and set into the recessed surfaces. A deformation force is applied upon the two arms to deform the body into a second configuration with the arms in abutting contact or nearly so at an outer tip or end.

    Abstract: A method for fabricating an artificial skin system such as skin for use with a robotics assembly. The method includes forming or accessing a digital three dimensional (3D) model of an object. The digital 3D model defines a topography of an exterior surface of the object. The method includes processing the 3D model to generate a 3D model of a core, including defining an exterior surface of the core with a topography that is an inverse copy of the topography of the exterior surface of the object. The method includes fabricating the core based on the core model, whereby the core has an exterior surface corresponding to the exterior surface of the core model. The core is used in dipping processes or injection molding processes to form a skin in which the exterior surface is formed of material that abutted the inverse topography of the exterior surface of the core.
