A topology optimization approach for designing large deformation contact-aided shape morphing compliant mechanisms is presented. Such can be used in varying operating conditions. Design domains are described by regular hexagonal elements. Negative circular masks employed to perform dual task, i.e., decide material states of each element and also, generate rigid contact surfaces. Each mask chara...

We compare in a laboratory experiment two audit-based tax compliance mechanisms that collect fines from those found non-compliant. The differ the way are redistributed to individuals who were either not audited or and be compliant. first, as is case most extant systems, does discriminate between un-audited second targets redistribution favor of find targeting increases when paying taxes generat...

We present a new manufacturing technology to produce multi-scale compliant feet for use with a novel climbing robot. Climbing robots for space exploration missions may allow scientists to explore environments too difficult for traditional wheeled designs. These climbing robot designs should be able to grasp or adhere to a variety of surface types at multiple angles in order to be effective. To ...

Bistable mechanical devices remain stable in two distinct positions without power input. They find application in valves, switches, closures, and clasps. Mechanically bistable behavior results from the storage and release of energy, typically in springs, with stable positions occurring at local minima of stored energy. Compliant mechanisms offer an elegant way to achieve this behavior by incorp...
