Immersive environment for water pumping station and fire system operation training

This paper aimed to create a 3D virtual reality simulator for automation training, becoming a training solution for monitoring, controlling, and operating a water pumping station and fire system to survey the industrial infrastructure of the virtual environment and design software. The Unity3D graphic engine was used, which develops the virtualization of the elements involved in the process with greater detail and realism. The interface of peripheral devices such as virtual reality glasses allows interaction and immersion between the user and the virtual environment to complement the learning experience. Within the immersive environment, the operator can see the status of the process and the actions generated through the virtual objects and instruments created in the 3D environment.

Virtual Training System for the Teaching-Learning Process in the Area of Industrial Robotics

This paper focuses on the development of a virtual training system by applying simulation techniques such as: Full Simulation and Hardware-in-the-Loop (HIL). This virtual reality system is intended to be a teaching and learning tool focused on the area of industrial robotics. For this purpose, mathematical models (kinematic and dynamic) have been considered. These models determine the characteristics and restrictions of the movements of a Scara SR-800 robot. The robot is then virtualized to simulate position and trajectory tasks within virtual environments. The Unity 3D graphic engine (Unity Software Inc., San Francisco, CA, USA), allows the design and development of the training system which is composed of a laboratory environment and an industrial environment. The same that contribute to the visualization and evaluation of the movements of the robot through the proposed control algorithm using the mathematical software (MatLab, manufactured by MathWorks, USA), through shared memories. This software in turn can be linked to an electronic board (Raspberry Pi) for data acquisition through a wireless connection. Finally, the stability and robustness of the implemented controllers are analyzed, as well as the correct operation of the virtual training system.

PA10 Robot’s Movement Through Natural Interface

<div><p class="4"> This paper introduces a natural interface for the movement of PA10 industrial robot and the implementation of its system. In order to evaluate the availability of these interfaces and the difference between the trajectory input by using its own development method and the trajectory executed by the robot, the mathematical model of PA10 robot is preliminarily established, and its motion is simulated in unity 3D graphics engine. Subsequently, the leap motion capture device is added as the main element of the natural interface, and tracks the movement of the user’s palm during the execution of various trajectories of the simulation software and the actual robot. The results show that the tracking error between the expected trajectory and the actual trajectory of PA10 robot is very small.</p></div>
