Abstract: Robots can protect healthcare workers from being infected by the COVID-19 and play a role in throat swab sampling operation. A critical requirement in this process is to maintain a constant force on the tissue for ensuring a safe and good sampling. In this study, we present the design of a disposable mechanism with two non-linear springs to achieve a 0.6 N constant force within a 20 mm displacement. The nonlinear spring is designed through optimization based on Finite Element Simulation and Genetic Algorithm. Prototype of the mechanism is made ...
