- ÍtemDiseño y fabricación de ala ZAGI, para la implementación de un sistema de inteligencia artificial para la detección de objetos(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Chacón Medina, Néstor Camilo; Morales Trujillo, Valeria; Aldana Rodríguez, DidierThe work was developed with the objective of designing and developing a flying wing or Zagi, with implementation of artificial intelligence for object detection, capable of stable flight, in addition to satisfying the requirements to compete in the ZAGI AESS RACE 2022 competition. During the development of the applied research, the profiles for the design are selected, as well as its construction material and simulations are performed to build the prototype and finally the final design. This resulted in a stable and controlled flight, occupying the 4th place. Additionally, artificial intelligence was implemented to make the designed aircraft capable of recognizing images, categorizing them especially for object detection, and sending the information recorded live to a ground station through a telemetry system compatible with the configuration of the designed aircraft, using Yolo, Python and Google Colab software and programming language.
- ÍtemEstrategia didáctica fundamentada en simuladores y su impacto en el nivel de competencias específicas relacionadas con circuitos eléctricos(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Duarte Báez, Víctor Julio; Aldana Rodríguez, Didier; Lozano Tafur, CristianJob training institutions are committed to training human talent with the high levels of labor competence demanded by the productive sector; that is why this research project focuses on determining if a didactic strategy based on simulators, significantly impacts the level of specific competence related to electrical circuits. To this end, this research work was approached in four phases, within which the sequence of the quantitative approach and the characteristic steps of the scientific method were sheltered. The research was developed using a quantitative approach, under the methodological principles of the explanatory scope, with a pure experimental design based on the four Solomon groups, with a sample of 124 trainees belonging to technical labor programs of the Triangle Institute in the city of Bogotá, who studied the electrical circuits module in the months of August and September of the year 2022. The survey and the educational evaluation were used as the main techniques, questionnaires and an educational test were used as instruments, all of them validated by expert judgment. The educational test allowed to establish at what level of specific competence in electrical circuits, the trainees were. To measure the relationship between the didactic strategy and the level of specific competence, the analysis of variance (ANOVA) was used, since the variables are quantitative and follow a normal distribution. For the 2X2 ANOVA analysis, the following values for p were obtained: for factor A (p=0.004164), for factor B (p=0.00001), and for the AB interaction (p=0.0003262) in all of them p<(α=0.05), in the same way in the analysis of the posttest by means of a factor ANOVA for the groups with pretest and without pretest, in both cases a value p=0.00001 was obtained which is less than α=0.05, indicating that there are significant differences between the groups that used a didactic strategy based on simulators as a training method and the groups that used the traditional method. This allowed to conclude that the intervention proposal was highly effective and the impact was significant, both in the pilot test and in its definitive implementation, allowing to attribute the causal relationship between the teaching method and the level of specific competence.
- ÍtemImplementación de un sistema de detección y evasión de obstáculos de bajo costo para drones de ala fija(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Aviles Correa, Cindy Lorena; Garzón Bernal, Jeison David; Aldana Rodríguez, DidierThe present work was designed and implemented in a prototype of a detection system of obstacles through different sensors such as: HD camera, LiDAR sensor, and a sensor infrared, installed on a Zagi-type fixed-wing drone manufactured for the project with the purpose to perform tests on the ground. The methodology consisted of merging the different codes of control of the two sensors and the camera to detect obstacles and send control signals to the servomotors that govern the control surfaces (ailerons) and to the brushless motor that gives push the drone and force. Several scenarios were proposed that were implemented through a logic defined in truth tables that through the generated control signal modifies the revolutions of the Brushless motor and the position of the flaps according to the distance at which it is detected an object, to generate an evasive response. The result is a didactic prototype low-cost functional, which allows understanding the operation and logic of information systems. detection and evasion for drones
- ÍtemLa lúdica como herramienta pedagógica en el fortalecimiento de las relaciones espaciales, en escolares de 6 y 7 años(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Mora Correa, Jennifer; Rodríguez Ortiz, Milton Giovanni; Aldana Rodríguez, DidierSpatial relationships are fundamental for the cognitive and operational development of individuals; for this reason, it is of vital importance to generate pedagogical strategies that contribute to their learning, development and strengthening. This research focuses didactic strategy mediated by the playful for the strengthening development of spatial relationships of children 6 and 7 years who are in transition grade and first Moralba Sur Oriental Educational District located in the San Cristóbal neighborhood of the city of Bogotá considering a theoretical foundation focused on constructivism, learning styles and playfulness. The methodology, developed through the combination of qualitative and quantitative approaches, for the collection of information was used to the application of the Boehm Test to inquire about spatial relationships and the Kolb Test to establish the learning styles of a group of 54 students of transition degrees and first of the IED Moralba, the technique of semi-structured interviews was applied to the three teachers who serve this population. The results showed that the greatest difficulties occur in the spatial relationships of laterality and order and that the main learning style of preference of the students is the kinesthetic followed by the visual. Therefore, the pedagogical strategy "My body discovers space" was designed, consisting of a total of eight class sessions in which it is intended to potentiate laterality and relations of order in students of the first years of schooling.
- ÍtemPropuesta de un procedimiento para la certificación de diseño y producción de componentes aeronáuticos clase II o III desarrollados mediante ingeniería inversa(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Lucero Figueroa, Oscar Fernando; Aldana Rodríguez, Didier; Hernández, Carlos ArturoThis research project has resulted in a series of guides to manage, manufacture and certify aeronautical components developed by reverse engineering, from design to production.
