Abstract—Robots are entering the technological age giving way to endless applications in the automation industry. Robots of different applications need suspensions systems to perform their logistic or agro-industrial activities. The aim is to design a mechanical vibration damping device that uses the principles of electromagnetism in order to control the magnetic viscosity, and thus the way it can absorb vibrations that are undesirable in robotic systems. This research project has a complete theoretical framework and quantitative approach to determining variables and measuring the response at the experimental and mathematical level. The theoretical framework explains the bases for the mathematical model. The method was based on five stages which are design specifications, preparation of schematics, electrical and mechanical tests, mechanical and electrical part coupling and prototype test. As key facts, a physical and mathematical model were designed for a shock absorber device with magnetic principles for robotic systems. The electric current of 1.6 A and a permeability of material 5001 are key variables that result in a damper magnetic viscosity γ = 7.32 T.m. Finally, authors conclude magnetic dampers can be used in unmanned robots allowing them to save energy on flat surfaces.
