Abstract

This paper presents a proposed alternative to simulate non-linear dynamical systems. This has an application in bachelor programs like: Electrical and mechanical engineering, Networks and Telecommunications engineering, Mechanical engineering and more, than they are taught in several public universities in Guerrero state. Commonly, the computer devices used for simulations require of high hardware capacity to support the simulation software. Moreover, the simulation software in the majority of the cases is under license permission. For these reasons, implementing a simulation lab in a public university is very high cost. Thus, we show an alternative by using a commercial development board Raspberry Pi supporting the GNU-Octave software, which is a free software, to simulate non-linear dynamical systems like a 4 grades of freedom SCARA robot and a rotational inverted pendulum. The comparision of the simulated dynamical models in both the specialized software and the proposed free software, exhibit the viability of the proposed alternative.
