Academic synergy through integrated mechatronic projects
(IEEE, 2018-01-01) Velasquez-Lopez, Alejandro; Rodriguez-Garcia, Alberto; Velasquez-Lopez, Alejandro; Rodriguez-Garcia, Alberto; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
This Innovative to Practice Work in Progress paper presents an approach to obtain synergy by implementing an integrated mechatronic project within a postgraduate program. Mechatronics has been a reference for synergetic integration of technology. However, synergy is obtained not only from technical issues, but through professional skills. Nevertheless, traditional education and industry standards focus only on the technical side. The study case is performed within the program Integrated Design of Technical Systems by implementing strategies such as integrated scheduling, integrated assessment and project proposal with application fields such as agriculture, robotics, health and mobility. This approach does not require additional credits for a project course, since the project lies underneath the courses. It has led to an increase of enrollment of students, which is significant during times when less engineers opt for further technical education.

Analyzing sliding bifurcations on discontinuity boundary of Filippov systems
(WORLD SCIENTIFIC AND ENGINEERING ACAD AND SOC, 2008-01-01) Arango, Ivan; Taborda, John Alexander; Arango, Ivan; Taborda, John Alexander; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
In this paper, we propose a novel method to analyze sliding bifurcations in discontinuous piecewise smooth autonomous systems (denominated Filippov systems) on the planar neighborhood of the discontinuity boundary (DB). We use a classification recently proposed of points and events on DB to characterize the one-parameter sliding bifurcations. For each parameter value, crossing and sliding segments on DB are determined by means of existence conditions of two crossing points (C), four non-singular sliding points (S) and thirty-five singular sliding points (T, V, Pi, Psi, Q or Phi). Boolean-valued functions are used to formulate these conditions based on geometric criterions. This method was proven with the full catalog of local bifurcations that it was proposed recently. A topological normal form is used as illustrative example of the method.

Characterizing points on discontinuity boundary of Filippov systems
(ACTA Press, 2008-01-01) Arango, I.; Taborda, J.A.; Arango, I.; Taborda, J.A.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
In this paper, we presented a basic methodology to understand the behavior of discontinuous piecewise smooth autonomous systems (denominated Filippov systems) in the planar neighborhood of the discontinuity boundary (DB). This methodology is useful in detection of nonsmooth bifurcations in Filippov systems. We propose a classification of the points and events on DB. This classification is more complete in comparison with the reported papers previously. The lines and the points are characterized with didactic symbols and the exclusive conditions for their existence based in geometric criterions. Boolean-valued functions are used to formulate the conditions. An illustrative example with a friction oscillator is presented.

CORRELATION BETWEEN PROCEDURAL AND CONCEPTUAL TEST IN A STATICS COURSE
(IEEE, 2018-01-01) Restrepo Garcia, Carlos Andres; Barbosa Perez, Jaime Leonardo; Restrepo Ochoa, Jorge Luis; Restrepo Garcia, Carlos Andres; Barbosa Perez, Jaime Leonardo; Restrepo Ochoa, Jorge Luis; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
Due to poor performance in Statics at Eafit University, since 2012 the Mechanical Engineering department implemented a virtual tool for the training and assessment of Statics course. Although the implementation led to better performance in the Statics course, students were still showing lack of comprehension of the basic concepts underlying the subject. The department applied a Concept Inventory test to 195 students from the second semester of 2017 in order to check if there was a correlation between the grades obtained in the class examinations and the performance in a conceptual test of Statics. The Concept Inventory was applied one week before the final examination and it was held inside the University facilities. The students were monitored all the time. For the course examinations were taken only three out of the four partial exams, they were computed and then compared to the results of the concept inventory. The results show that almost all the students with the highest grades in the class performed above the mean in the Concept Inventory. The overall mean for the conceptual test was 9.27 and the standard deviation was 5.28. The course grades were discriminated by career and an Analysis of Variance was conducted to determine if there were significant differences among the groups. A correlation analysis suggests that there is not a strong correlation between the course grades and the concept inventory results. One possible explanation for this can be due to the fact that the regular teaching method for these kind of basic courses in engineering in the University is merely procedural and problem-solving oriented, conceptual approaches are often neglected in both teaching and assessment.

This work-in-progress research paper presents a study on employability skills. Employability or soft skills refer to personality traits, attitudes and behavior that are complementary to professional knowledge. These skills are part of a series of competencies that are intertwined with the engineer's technical work [1]. A high percentage of job success depends on employability skills [2]. A gap exists between the attributes of engineering graduates and company requirements [3]. Experiential learning can develop a myriad of skills required by the workplace. Universidad EAFIT, located in Medellin (Colombia), has developed an experiential learning program called KRATOS. KRATOS was sent an invitation to participate in an international competition that implied designing and building a solar/ electric powered vehicle. Think creatively is a competency that is important for engineering practice across areas, disciplines and countries [1]. Although student competitions that include design activities may enhance a passion for engineering, they can also have negative emotional consequences [4] (i.e. job tension). Using the structural equation modeling technique, the authors of this study analyzed the responses of 334 undergraduate students. The results of the study indicate that job tension significantly decreased over time, whereas no significant change was detected in terms of creativity.

Design of a new fully compliant translational joint via straight-line motion mechanism based method
(American Society of Mechanical Engineers (ASME), 2019-01-01) García S.C.; Gallego-Sanchez J.A.; García S.C.; Gallego-Sanchez J.A.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
A Compliant Translational Joint (CTJ) is designed via Straight-Line Motion Mechanism Method. The designed CTJ is based on the Pseudo-Rigid-Body-Model (PRBM) of a modified Scott-Russell Mechanism. The precision of the straight-line motion of the rigid-body mechanism adjusts to a straight-line to a 99.6% while the compliant version adjusts to a 99.9%. The novelty of the design is given by the way the CTJ is designed, the performance of the CTJ is achieved by mirroring the mechanism about an axis tangent to the path of the mechanism and that passes through the initial position of the coupler point at the symmetry axis of the path. The CTJ motion is predicted by the PRBM. The force-displacement relations and the frequency modes of the CTJ are analyzed using finite element analysis (FEA). Copyright © 2019 ASME.

Design of a statically balanced fully compliant grasper
(Elsevier Ltd, 2015-10-01) Lamers, A.J.; Gallego Sánchez, J.A.; Herder, J.L.; Lamers, A.J.; Gallego Sánchez, J.A.; Herder, J.L.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
Monolithic and thus fully compliant surgical graspers are promising when they provide equal or better force feedback than conventional graspers. In this work for the first time a fully compliant grasper is designed to exhibit zero stiffness and zero operation force. The design problem is addressed by taking a building block approach, in which a pre-existing positive stiffness compliant grasper is compensated by a negative stiffness balancer. The design of the balancer is conceived from a 4-bar linkage and explores the rigid-body-replacement method as a design approach towards static balancing. Design variables and sensitivities are determined through the use of a pseudo-rigid-body model. Final dimensions are obtained using rough hand calculations. Justification of the pseudo rigid body model as well as the set of final dimensions is done by non-linear finite element analysis. Experimental validation is done through a titanium prototype of 40 mm size having an unbalanced positive stiffness of 61.2 N/mm showing that a force reduction of 91.75% is achievable over a range of 0.6 mm, with an approximate hysteresis of 1.32%. The behavior can be tuned from monostable to bistable. The rigid-body-replacement method proved successful in the design of a statically balanced fully compliant mechanism, thus, widening the design possibilities for this kind of mechanism.

Design to Achieve Accuracy in Ink-Jet Cylindrical Printing Machines
(MDPI AG, 2019-01-11) Arango, Ivan; Cifuentes, Catherine; Arango, Ivan; Cifuentes, Catherine; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
Machines for direct digital inkjet printing on cylindrical containers are a new technology out on the market. The commercialization in the industrial sector has been affected by their high precision. This led to the use of mechanisms with narrow manufacturing tolerances and to the searches for topologies that have the least accumulated error without affecting quality. Machines with topologies that work on flat substrates have printing and productivity problems working on cylindrical substrates. This research paper presents the qualitative design of direct digital inkjet printers working over cylindrical substrates comparing five mechanical topologies; three topologies with radial distribution and two topologies with parallel distribution. The aim of these topologies is to find the precision, quality and efficiency of the printer taking into account the restrictions present in its construction. Each topology has separate constitutive mechanisms, the tolerance ranges between the movements of the print head and the substrate in order to determine precision are analyzed. Out of the five topologies described and analyzed in the phase diagram in section 3, three of them meet the requirements. One of the three topologies that meet the requirements is not being developed due to current technological limitations.
Detecting Sliding Areas in Three-Dimensional Filippov Systems using an Integration-Free Method
(WORLD SCIENTIFIC AND ENGINEERING ACAD AND SOC, 2008-01-01) Arango, Ivan; Taborda, John Alexander; Arango, Ivan; Taborda, John Alexander; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
In this paper, we detect sliding areas in three-dimensional (3D) Filippov systems using an integration-free method denominated Singular Point Tracking (SPT). Many physical applications in engineering can be modelled as Filippov systems. Sliding dynamics due to nonsmooth phenomena as friction, hysteresis or switching are inherent to Filippov systems. The analysis of sliding dynamics has many mathematical and numerical difficulties. Several well-known numerical problems can be avoid using integration-free methods. In this paper, we extend the SPT method to 3D Filippov systems. In comparison with the 2D case, the evaluation of the vector fields on the discontinuity boundary (DB) should be reformulated and new dynamics on DB should be characterized.
DEVELOPMENT OF AN AUTOMATIC PLOTTER FOR GENERATING EXERCISES FOR STATICS COURSE IN ENGINEERING
(IATED-INT ASSOC TECHNOLOGY EDUCATION A& DEVELOPMENT, 2016-01-01) Restrepo Ochoa, Jorge Luis; Barbosa Perez, Jaime Leonardo; Arenas Berrio, Julian; Restrepo Ochoa, Jorge Luis; Barbosa Perez, Jaime Leonardo; Arenas Berrio, Julian; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecatrónica y Diseño de Máquinas
In the virtual platform for Statics course of Engineering School at EAFIT University it was implemented an automatic plotter for generating exercises to study truss type structures and beams in civil, mechanical and production engineering. Through graphics changes, range of variables and requested questions, the student is provided with different exercises each time that they log in to the platform, achieving the personalization in the learning and evaluation process. The plotters for the structures are developed in JAVA language, and the questions generated are converted into a compatible format with the management learning system MOODLE. Since 2012, the engineering students' population who have enrolled the Statics course is 1909 and all of them have solved exercises generated with automatic plotters. From the design of an automatic generator an unlimited questions bank is obtained to implement in the virtual platform, it allows to get security when applying evaluation tests due to the fact that each person solves a different question. The present study shows the design and programming methodology used to make plotters so it can be extended to others virtual environments in basic sciences. Future works consists in making automatic generators that allow to define difficulty levels to guide the students in a progressive study in the course topics.
