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. In some examples, a crimp for mechanically joining rebar for use in a support system for a physical structure includes a body with at least two recessed surfaces each configured for receiving a respective first and second piece of rebar; and a pair of spaced-apart arms at least partially enclosing an interior space of the body including the at least two recessed surfaces, a first tip and a second tip of the respective spaced-apart arms each defining a respective first and second opening to the interior space, in a first configuration.

A robot that includes two or more skeletal or rigid links interconnected by a joint. The joint is pneumatically actuated and includes a pneumatic joint actuator that allows the robot's skeletal links to be moved in an expressive manner. The pneumatic actuator includes a pair of opposing air bladders encased within a housing or body of the joint. Each air bladder is positioned on an opposite side of an actuating lever arm, which is rigidly attached to one of the skeletal links and is pivotally mounted on the joint body or housing. Movement of the actuating lever arm causes the attached skeletal link to pivot. To obtain this selective movement, one of the two air bladders is filled with a gas, such as air, while the other is left un-inflated or less inflated, and this forces the lever arm and attached skeletal link to pivot about their mounting point.

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.

A system for performing simulation-based material characterization includes a computing platform having a hardware processor and a system memory storing a software code. The hardware processor executes the software code to obtain a result of a physical test performed on a material, selects a parameterized model of the material based on the obtained result, and performs a simulation of the physical test using the parameterized model to generate a simulated result. The hardware processor further executes the software code to compare the simulated result with the obtained result of the physical test on the material, and adjusts one or more parameter value(s) of the parameterized model, based on the comparison, to improve the simulated result, and predict, after adjusting the parameter value(s), one or more characteristics of the material based on the parameterized model.
