In the electronic engineering undergraduate program, Peruvian universities offer different theoretical courses of Automatic control that do not present enough practical approach to the algorithms that are studied during the progress of these courses; however, the approach to implementation is very important to achieve good performance in the industry and researching. In this work is presented XSpace, an innovative and friendly platform which consists of a robust hardware that allows the student to take it home; this way, the student is given the opportunity to implement digital control algorithms learned in the theoretical classes. The effectiveness of this platform is shown using a proposed methodology which evidences greater interest, efficiency and efficacy in students at the Automatic control area. This project was implemented in the “control Systems” course at Pontificia Universidad Catolica del Peru (PUCP) from 2020 to 2022. Results are presented through a student survey and a history of average grades during the academic periods the platform was employed.

Visual odometry (VO) is a method used to estimate the spatial movement of vehicles or camera-equipped systems by analyzing visual data from the environment. It is a cost-effective and accurate alternative to systems like Global Navigation Satellite Systems (GNSS) and Inertial Navigation System (INS), and is particularly favored in autonomous vehicles, unmanned aerial vehicles (UAV s), and augmented reality applications. This study focuses on the performance challenges faced by visual odometry systems in low-light environments, where traditional systems may not be effective and presents a novel approach, Contrast-Adaptive Block Optimization (CABO), to enhance VO in low-light environments. CABO divides images into blocks and selectively applies Contrast Limited Adaptive Histogram Equal-ization (CLAHE) to darker regions, optimizing image quality without compromising natural appearance. By improving feature extraction and matching, CABO enhances VO accuracy and robustness. We utilized the Karlsruhe Institute of Technology and Toyota Technological Institute (KITTI) dataset, we demonstrate the effectiveness of the proposed method in improving position and orientation estimation under challenging lighting conditions.
