This paper presents the results of a research project for developing Rusty Roads, a videogame that simulates line follower robots in tridimensional, competitive environments. During the software development process, it was necessary to define the key physical factors that could affect the performance of the robot. A real robot was considered to define real parameters for the simulation, and to define discrete equations for simulating the robot in the Unity framework, comparing their accuracy with that of continuous, exact equations specifically developed for this study. This paper presents the process for obtaining and testing those equations, which were the foundations for the successful development of the simulation layer of the videogame and allowed the subsequent creation of its 3D visualization component.

This paper analyzes the vehicular mobility in 3 specific points of the municipalities of Riohacha and Maicao, La Guajira Colombia. Variables of vehicular flow such as queue arrival times, density, permanence, infractions and other implicit ones were used. Observation and description processes are carried out over four continuous months in critical hours; the flow variables that affected the selected points, causes and effects were identified and described, which are represented using influence diagrams. The whole process was simulated, using high performance software such as PTV Vissim 8 and Vensim PLE. It is recognized that the vehicular mobility in the studied points, the congested genres due to the high frequency of vehicles that transit and that the current traffic regulations are something that don't help enough to improve the flow. In addition to infractions, accidents and situations of intolerance, toxicity is generated in the environment by the emission of CO2 by vehicles waiting at each critical point, matters to which authorities still do not pay attention.

This paper presents and analyzes a flipped classroom proposal for teaching production programming technics, with the aim of increasing the interest, collaboration and satisfaction of the students in comparison with traditional teaching. A real size production plant problem is presented to the students in order to make decisions on tactical level and operative level. To make the decisions, the concepts linked to the different tools are supplied to the students, with the support of software applications. These incorporate smart technics applied to each step of the planning process. The effectiveness of the tools in the key indicators of production area are validated calculating indicator values that could be used as student grades criteria. The qualitative evaluation of preliminary tests shows that the use of this kind of educational model improves motivation, professor-student interaction and academic performance.

In this paper the basic structure and design of a torque controller for an electric vehicle driven by induction motor is presented. The basic structure of the electric vehicle in question and its mathematical model is presented first. After that, the operation principle of the conventional direct torque control is analyzed and from this a new controller with fixed constant switching frequency is designed. To generate the switching pulses sine PWM is used instead of the hysteresis comparator and switching table commonly used in direct torque control. Finally, simulation comparison was performed. This shows that better performance was achieved with the proposed controller with lower torque and flux errors, and lower torque and stator current ripple. [ABSTRACT FROM AUTHOR]
