Mechanism optimization of biomimitic microrobot by finite element modeling

Abstract

the manuscript favors the internal mechanism of a flying micro-robot in a context linking the mecatronic parameter and aerodynamic constraints. The results are based on the modeling under the COMSOL multiphysics CAD tool and the experimental analysis. The study is carried out on different structures achieving an optimal wing flap. The simulation is made with the characteristics of a commercial micro-motor. We determine the wing beat frequency necessary for flight analytically. The mechanism is made with different 3D printable materials. Different contexts will be examined and compared according to the constraints studied "thermal, physical, structural". In this study, we demonstrate the influence of heat, thickness, and 3D printable material as a function of the modeled structure. We concluded that the structure requires a compromise between flexibility and rigidity. The material chosen is heat resistant. The thickness and the weight influence the stability of the micro-robot.
