An automatic system for defect detection in plastic crates for glass bottles.
Juarez, Matthews; Cruz, Anderson De La; Vinces, Leonardo; Vargas, Dante
The project describes the design and implementation of an automatic system for detecting defects in plastic crates for glass bottles. In all companies there is damage and defects in their cases, crates, or containers due to constant use, as they are reusable, and therefore this problem causes various economic losses and a decrease in production, especially in beverage companies. This system was designed to solve and prevent the crates from having defects in their base and containing waste inside, to obtain less product losses in the bottle packaging area. In this research, it is proposed to design the automatic system, which consists of training a convolutional neural network with a database of 136 photographs of waste and defects in the boxes that will be taken by the HQ Raspberry Camera; then programmed into the Raspberry the process of activating the engine so that the box is moved to the point where it will be detected by the photoelectric sensor and the inspection is performed; and finally it is classified indicating whether or not it is in optimal conditions. This is developed in Python using different libraries such as OpenCV, TensorFlow, Tkinter among others. Our results show that the classification and object detection accuracy reached 91.84% out of a bank of 264 tests performed.

Optimization of the dimensions of the Tablachaca sand trap dam with the application of HEC-RAS in Peru
Guillen, Carlos Banos; Aguila, Juan Diego Guerra Del; Gutierrez, Ruben Mogrovejo
This article will detail the steps to model a sand trap in the HEC-RAS software and once modeled, which variables can be modified to obtain greater decantation of particles in the sand trap. The sand trap to be modeled is the one found in the Tablachaca dam. In the first place, the process of designing a sand trap and the variables involved will be explained. Then, it will be explained which variables of the sand trap and contour (environment) intervene in the modeling, to develop the numerical modeling in the HEC-RAS software. It has been determined that the sand trap is divided into 4 naves, each approximately 9 meters wide and 120 meters long, and, for modeling, it was decided to model a single nave. Data on the granulometry of the sediments and flows that reach the Tablachaca dam were obtained from previous works. When modeling the sand trap in HEC-RAS, there is a sedimentation layer of approximately 2.54 centimeters on the side closest to the dam (downstream).

Currently, industries need to reduce production times, eliminate the possibility of human errors, and increase company profits. However, this is quite challenging since operators, working long hours each day, are prone to making mistakes due to fatigue or the use of outdated techniques. Taking this into account, this paper proposes the development of a hybrid suction and cutting gripper utilizing a Fletcher cutter attached to a KUKA KR60 robot responsible for cutting and transporting raw glass. The robot's motion is programmed using Kuka Sim Pro, while the design and stress analysis of the hybrid gripper were performed in Inventor. The result was an automated system capable of achieving cuts with a precision of 0.025 mm and a speed ratio of approximately twenty cutting and transportation processes per hour.

A multi-purpose Gripper for KUKA KR-60 welding robot and inspection chamber

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 helps us to establish the reference systems for each link of the robot. Firstly, MIG welding is used. Secondly, we wait for a short period of time to let the weld bead cool down, then we use the dremel tool with a twisted conical brush accessory to perform a little reaming to remove some surface impurities. Finally, after waiting a short period of time for the effect to take effect, a Logitech c922 camera is used to capture an image of the bead and perform image processing to see what type of imperfection the weld has. The design uses duraluminium, MDF, zinc-plated rods and ABS filament for the 3D printer. The expected result is to obtain a correct quality control of the welding to guarantee the durability of the fundamental part of the vehicle.

A training system for taekwondo players with impact and linear displacement data collection

Currently, technology does not accompany Peruvian high performance Taekwondo athletes in an efficient way where there is the ability to read all the physical performance data, obtain a database of it constantly and have a system that allows practicing the slide that is often used as footwork. It should be noted that there is not much prominence of the robotic sector to be applied in sport as well as the lack of data records of specific variables that can quantify the skill of high-level taekwondo players. Therefore, the purpose of this article is to promote technological assistance to increase competitiveness in Peruvian taekwondo players and to improve their physical performance. For this purpose, a training system was implemented, which has 'dommys' (kicking shields) of the official brand 'JCALICU' conditioned with a wooden plate, load cells and piezoelectrics for the reception of kicking data. There is also a paddle that will move radially to receive the axe type kick and, for the linear displacement, a motor with chain transmission will be used. The methodology used is programming, I2C serial communication, numerical simulation and PID control. The result is a training system capable of linear displacement and of displaying the data of force, reaction time and precision of the athletes' kicks in a graphic interface.

A design of a distillation column to produce an alcoholic beverage based on Blueberries
Susuki, Ken; Ipanaque, Andres; Vinces, Leonardo
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 FenskeUnderwood-Gilliland methodology. Additionally, electronic, and electrical equipment were carefully selected to ensure a robust system capable of withstanding unfavourable climates and environments. The designed system was validated through a temperature-induced mechanical stress analysis using ANSYS R2 2022, followed by numerical simulation. With this innovative mechanical design and temperature control system, a production ratio of 1:7 was achieved compared to the initial batch of 50 L of blueberry must for a blueberry-derived alcoholic beverage with a 40% alcohol content and the presence of antioxidants concentration such as resveratrol.
