Identification of a dynamical model and its parameters is one of the fundamental problems in the field of robotics and system dynamics modelling. For the general situation of an object motion with six degrees of freedom (6-DOF). such as in the case of the Unmanned Aerial Vehicle (UAV). the key physical parameters are vehicle mass and moment of inertia. https://allfixelectricales.shop/product-category/fridge-hinge-end/
