The robotic mobile system Robotino, developed by FESTO, is a robotic platform oriented towards research and education, which is why it has a reduced amount of actuators of limited real functionality. This article proposes the integration of a Raspberry Pi 4 to a Robotino FESTO with the purpose of expanding the number of digital inputs this robot has, in addition to allow the input of analog signals by serving as a communication interface between devices through an ethernet connection. In this way, the installation of robotic arm Lynxmotion AL5 with 5 degrees of freedom to the Robotino through the Raspberry Pi 4 is proposed so that it performs additional functions and applications without interfering with the digital inputs of the Robotino, that are already used by the sensors and accessories installed by default. By establishing the connection between both devices (Robotino and Lynxmotio...

This paper presents the numerical simulation of a 3D mechanical design of an ankle exoskeleton for elderly users. The ankle is one of the most injury-prone joints due to its irregular - sphere shape and elderly people are more prone to this damage (approximately 80% of patients with a history of ankle sprain undergo surgery for post-traumatic ankle osteoarthritis [1]). This problem generates a decrease in muscular resistance on the legs, loss of motor skills, loss of mobile autonomy, etc. The simulation of this exoskeleton is intended to reduce these problems by means of this low-cost mechanism, since similar options exist, but they are not within the economic reach of all. For this reason, anatomical measurements of an elderly user were taken to obtain an ergonomic and easy-to-use mechanical design. Biomechanical calculations were also performed on the ankle to define its displacement a...

Nowadays, bottling industries perform inefficient maintenance and transportation sub-processes, such as: boxing, unpacking, and selecting. These functions are performed by workers during long hours, which causes delays in the general production process, risks in the safety of personnel and integrity of the bottles, a tendency to a greater number of errors and especially, severe medical problems caused in the long term. In view of the advantages of industrial automation, it is known that it makes use of the union of engineering knowledge to facilitate procedures and guarantee reliability. This is the case of industrial robots that are increasingly required to optimize numerous systematic strategies in many fields; however, it is complex to develop an autonomous artifact that adapts to variable changes in different environments.

The present work proposes an analysis of the internal temperature flow in two types of helical coils, whose number of turns is 6 and 10, for the sugar cane bagasse delignification process, using superheated steam as a heat source. The analysis seeks to find the ideal number of turns for the process, the inlet pressure, and the temperature range in which the coil should operate to provide the working temperature for the reaction. This proposal will be carried out using Ansys fluent version 19.2 educational simulation software, where the coils were designed and the temperature and pressure parameters of the superheated steam flow to travel through the internal part of the helical coil were introduced. As a result, with a number of coils of 10 and an inlet pressure of 0.4 MPa, an efficiency of 96.545% was achieved to maintain the temperature along the coil path. This allows its application ...

The present work proposes the design of a hydrodynamic profile for unmanned submarine devices through numerical simulation, thus facilitating experimental studies and reducing manufacturing costs. Design and manufacturing aspects of different authors were studied to establish a highly maneuverable vehicle, capable of moving in the horizontal and vertical plane. For this reason, the final design proposes hydrodynamic profiles in the bow and stern using the “Myring” equations. It also has cross-shaped hydrodynamic fins located in the bow, which will help reduce the drag coefficient. Therefore, this work aims to study and analyze the hydrodynamic characteristics of the submarine using the ANSYS Fluent software. Likewise, the drag coefficient will be analyzed for different operating speeds, in order to know what is the maximum drag force that should be overcome to move at that speed. Fin...

In this work, a mini wind turbine was developed that takes advantage of the kinetic energy of the winds around a moving car. The blades were designed according to inclination angles in order to capture as much energy as possible without greatly affecting the performance of the vehicle. Various proposals are presented according to the inclination of the angle of the blades with respect to the axis of the turbine. Likewise, the behavior of airflow over the blades will be studied using CFD techniques. In addition, it will be possible to obtain various parameters such as the drag coefficient that will serve for the optimal design of the turbines. Finally, experimentation will be carried out to evaluate the electrical energy that said turbine can produce when coupled to a mini generator. The results show that the most optimal design is proposal 2 because it is the one that produces more volta...

This article focuses on the development of an autonomous navigation system by generating real-time 3D maps of different urban environments with different properties within simulation software. This system used the Pioneer 3-DX vehicle, a LiDAR sensor, GPS, and a gyroscope. For the elaboration of the trajectory, the mathematical tool of artificial potential fields was used, which will generate an attractive field to a dynamic goal identified by the robot and repulsive to the obstacles present in the environment, recognized with great precision thanks to the use of a neural network. The topology neural network 8–16–32 was developed using forward propagation, reverse propagation, and gradient descent algorithms. By combining the tools of potential fields and neural networks, a path was traced through which the robotic system will be able to move freely under an off-center point kinemati...

Corn production in Perú during the last five years has been reduced for various reasons and the inefficient application of technology, because the progress of technology has been decreasing the intervention of the human hand in the field. For example, the use of automated pivot irrigation systems has had a positive impact on the efficiency of irrigation administered to the plants; however, this system has resulted in the neglect of the plants in the first months, generating a final production lower than that estimated for each harvest season. In view of this, the use of Unmanned Aerial Units (UAV) is proposed in order to collect soil samples around the cultivated field to be delivered to the laboratory for analysis. This mechanism consists of an arm with two degrees of freedom including an extractor that presents an auger with a worm inside, in turn it will have a rotational movement th...

In various industries, the fruit is utilized to produce derivative products such as beverages, vitamin C masks, jam, ice cream, pastries, among others. This highlights an area that has not been thoroughly explored: its use as a raw material, once fermented, to produce a distilled beverage with a strong presence of antioxidant properties. Various mathematical calculations were performed to obtain a column capable of distilling the fermented product at a maximum temperature of 98 ^{\circ}\mathrm{C} without damaging the antioxidant compounds present in blueberries. Therefore, calculations were made for the number of stages required in the distillation column, the column diameter, the distance between stages, and the simulation of the distillation process for the fermented blueberry must. Therefore, a novel mechanical design of the distillation column was carried out using the rigorous Fensk...

At present, imperfections are still observed in the welding of the vehicle chassis, due to the fact that the inspection of the welding seam is still carried out manually. In other words, there are still companies that depend on an operator to verify the welding, which has resulted in less durability of the vehicle chassis, as they do not have adequate reinforcement when entering areas where greater strength and traction is required. For this reason, the use of a gripper is proposed, the purpose of which will be to carry out and inspect the weld seam. This mechanism consists of the use of 3 tools: MIG torch, dremel and camera, each tool will be used in a certain period of time independently in order to guarantee the correct welding seam. For this purpose, the analysis of the behaviour of the robotic arm will be taken into consideration by using the Denavit Hartenberg algorithm, which help...

Precision agriculture brought with it the implementation of new digital technologies, mainly autonomous vehicles, satellite images, IoT and artificial intelligence, to provide economic, productive, and environmental benefits in the agricultural field. However, the main applications are focused on data management and monitoring of crop fields, so agricultural processes such as planting and harvesting are not yet fully automated. A clear example of this occurs in the cultivation of rice, which despite being one of the most important agricultural products in the world, the manual production method continues to predominate in developing countries. This work presents a design of an autonomous terrestrial vehicle capable of carrying out the rice transplantation process, having as its main characteristics its ability to move in the field of cultivation at a speed of 0.75m/s, transport a payload...

3D printing is widely used due to its versatility and low manufacturing cost, but this manufacturing method has limitations such as the use of only 3 degrees of freedom that consists of extrusion by layers contained in the XY plane with displacement high on the Z-axis. On the other hand, there is the printing volume which is reduced, and finally the loss of material that occurs when having supports. Next, a versatile procedure is presented, which is mounted on a KUKA KR60 robotic arm, with which complex surfaces can be printed and of a larger size with the help of the robot arm's work area, parts with concave surfaces, and convex where printing supports are removed. This proposal intended to have a printer mounted on a KUKA KR60 robotic arm with which you can have 6 degrees of freedom, and use approximately the cubic meter of freedom that the arm has. This achieves prints with greater co...
