The ancient art of origami can act as a powerful tool towards the development of adaptive structures that has a diverse field of application. This can be enhanced with biomimetics, the study and development of synthetic mechanisms that mimic the structure or functionality of biological organisms. As the name suggests, the origami-enabled pill-bug structure draws inspiration from pill-bugs, a species of woodlice. This paper characterizes the dynamic response and the quasi-static form-finding of origami-enabled pill-bug inspired adaptive tuned-mass damper. The distribution of such independently operating tuned-mass dampers in a spatial grid will be useful to attenuate vibrations to address challenges in variable stiffness and complex seismic responses. When the seismic excitation is low, the pill-bug tuned-mass damper is in an inactive unrolled state. Accelerations above the threshold value activate the tuned-mass dampers and initiate the rolling process in stages. The objective of this study is to simulate and experimentally validate the topology and response of the origami-enabled pill-bug-inspired tuned-mass damper.
