This work shows a systematic review of literature of machine learning and audio processing for applications in preventive maintenance. It intends to prove how audio signal processing combined with Machine Leanring techniques can produce a powerfool tool to detect anomalies and malfunctions in electromechanical devices. The document describes a review of art state and the algorithms that can be use...Show More
In this work, we proposed to evaluate the use of the Arduino Science Kit Physics Lab as a low-cost tool for conducting self-guided physics laboratory practices using a project-based learning approach for undergraduate students at the Universidad del Cauca. Our main hypothesis is that the guides permit to realize the practices with the kit as an alternative to virtual and remote learning environmen...Show More
This paper presents the results obtained in the design and construction proposal of a 12 DOF bipedal robot, based on the ROS operating system for the balance experiments during the static standing phase and generation off-line gait joint trajectories. This robot was made with electronic and structural features, looking to omnidirectional walk. ROS operating system used, to have a distributed execu...Show More
This paper presents a teaching tool for modeling and control of dynamical systems using a project-based learning approach, which allows engineering and basic science students to develop programming and electronic design skills through the use of fundamental physics. The tool has two main components. The first one is a program that obtains the mathematical model of an electrical circuit from experi...Show More
The aim of this article is to make a comparison between the performance of a dynamic control and two linear controllers: PID Control and a Linear Quadratic Regulator (LQR) Control when they are designed for the balance of a Robotic Bicycle. The research is focused on determining the best controller for the robot using two different performance indexes: (i) the standard deviation of the lean angle,...Show More
This paper presents a simplified second-order dynamic model of the Arduino Engineering Kit robotics bicycle. We design and implement a closed loop control strategy, that minimizes the tracking error and rejects disturbances generated by uncertainties and unmodeled dynamics. The proposed controller allows the steering to rotate to the right or to the left to counteract its inclination similar to an...Show More
Most common methods for proper 3D capture of human movement require a laboratory environment and setting of markers, sensors accessories body segments. However, the high cost of these equipments is a limiting factor in our work environment. Motion capture systems like Microsoft's Kinect TM camera present alternative new approaches to motion capture technology. This paper proposes the design and im...Show More
