    The aim of this work is develop and configure a three-dimensional animation of a robot in virtual reality environment using the Unity software. The movement of the robots uses mechanical principles which considers that the degrees of freedom must be controlled independently through a microcontroller. In addition, the necessary steps are shown to transfer the three-dimensional model of a robot developed in a CAD tool to a virtual simulation environment without losing the physical characteristics of the original design. In the analysis of results, the simulation is shown in a virtual environment, considering real physical parameters together with the movement of a hexapod robot of 18DOF.

    Predictive Maintenance (PM) plays a crucial role in maximizing efficiency and reducing costs associated with equipment and system maintenance in industrial companies. Recent advancements in Machine Learning (ML) have revolutionized PM by offering accurate and efficient fault prediction and maintenance planning capabilities. This research focuses on monitoring a bench grinder and observing sensors for temperature, current, angular velocity, and vibration under normal operating conditions. The objective is to predict failures based on specific variables related to the machine. To develop the system, a prototype bench was designed to subject the machine to several working scenarios, collecting real-time sensor data. Data clusters were generated for each sensor, collecting 3000 samples over 7 consecutive days without faults and another 7 days with modified bench grinder behavior. Sampling was done at a rate of 1 second. The performance of Decision Trees (DT), Support Vector Machines (SVM), Naive Bayes (NB), and K-Means + Neural Network (NN) algorithms was compared using the confusion matrix metrics. Each algorithm's performance was evaluated for RPM, current, temperature, and vibrations measures. The SVM algorithm showed the highest error for RPM with 43.5%. In contrast, all algorithms achieved minimal or zero errors for vibrations, indicating excellent performance. These findings demonstrate the potential of ML algorithms in PM for the bench grinder. The results highlight the importance of selecting appropriate algorithms for specific measurements, with vibrations exhibiting the least error across all algorithms and contributes to optimize maintenance activities in industrial settings.
