This paper proposes the geometry-based polylinal routing method as a solution for motion planning in object sorting exercises in manufacturing processes. This algorithm is based on geometric properties that arise from the interaction among objects within the configuration space. The method proposed in this paper, during its experimental phase, successfully generated smooth routes with a processing time ranging from 62.5-125 ms on a computer equipped with an AMD Ryzen 7 2700X Eight-Core 3.70 GHz processor and 16 GB of RAM. When compared to the RRT algorithm, it exhibits a higher efficiency of 38% to 48%, resulting in a reduction in iterative processes and a shorter response time. Therefore, the proposed method presents a viable solution for addressing motion planning scenarios in object sorting exercises. [ABSTRACT FROM AUTHOR]

There is an increasing interest and growing practice in Citizen Science (CS) that goes along with the usage of websites for communication as well as for capturing and processing data and materials. From an educational perspective, it is expected that by integrating information about CS in a formal educational setting, it will inspire teachers to create learning activities. This is an interesting case for using bots to automate the process of data extraction from online CS platforms to better understand its use in educational contexts. Although this information is publicly available, it has to follow GDPR rules. This paper aims to explain (1) how CS communicates and is promoted on websites, (2) how web scraping methods and anonymization techniques have been designed, developed and applied to collect information from online sources and (3) how these data could be used for educational purposes. After the analysis of 72 websites, some of the results obtained show that only 24.8% includes detailed information about the CS project and 48.61% includes information about educational purposes or materials.

The increase of mining in certain historical periods can be attributed to the incidence of various factors, such as the price of metals, technological development, and economic and environmental policies. This paper reviews the most important periods of mining development in Mexico, examining in depth the most recent period: the implementation of automation. The majority of social analyses related to mining have focused on the concept of neo-extractivism and have emphasized economic policies and prices. This paper's contribution is a review of the data of the revolution in the mining sector's productive forces. This is an aspect that may be as important as metal prices and the sector's economic policies when seeking to understand the current situation. [ABSTRACT FROM AUTHOR]

This paper analyzes the effects of new technologies oriented to automation in the Chilean labor market. A general equilibrium model is used, in which the investment in robotic capital and the investment in traditional capital are considered separately, allowing the study of the effects of complementarity and substitution that are verified in relation to the labor factor. In particular, the model treats robotic capital as a direct substitute for labor, while incorporating traditional capital as complementary to it. By subjecting the economy to shocks in robotic capital prices, the effects on consumption, employment, wages and GDP can be studied. The results indicate that a fall in the international purchase price of robotic capital has a negative impact on employment as well as on the product. The exercises carried out in this study indicate that a decrease in the international price of robotic capital by 1 %, under conditions of high replacement rates between employment and robots, produces a drop in employment and wages of 0.05% if the change is transitory and of 0.25% if it is permanent due to an increase in imports of robotic capital.

This paper presents the design and implementation of a multivariable system control for a productive process of drying of wet product on a Jet dryer, using PI controllers and simplified decoupling. The main goal of this implementation is to reduce the amount of non-compliant product that is generated at a company in the mining sector, for manual manipulation of input and output variables, by the strong interaction between them and the effect of the disturbances in the process that generated losses both in time and in the product. For the design, an identification of the process was carried out, then the PI controllers were estimated offline and finally the decoupling design was made. The results yielded from the simulation and the implementation in the process demonstrated the effectiveness of the designed control system. [ABSTRACT FROM AUTHOR]

Promises of ‘teacher-light' tuition and of enhanced ‘efficiency' via the automation of teaching have been with us since the early days of digital education, sometimes embraced by academics and institutions, and sometimes resisted as a set of moves which are damaging to teacher professionalism and to the humanistic values of education itself. However, both the embrace and the resistance can be seen to be anchored in a humanistic orientation to the project of education which recent work in the theory of critical posthumanism draws into question. Working within the broad frame of critical posthumanism, this paper will revisit the notion of teacher automation in higher education, exploring how as teachers we might enact new, resistant ways of playing at the boundaries of the human and machine.

In different areas of Mechanical Engineering: agricultural, industrial, automotive, electrical, administrative, mechatronics, mining, hydraulics, health area, etc., most machines have hoses. The industry specialized in its design and construction undergo a great challenge and each day devoted efforts to improve the production process of hoses, made from plastic to manufactured metal or other materials. In order that these materials have greater stiffness and strength (ability to withstand high loads without being deformed or destroyed), the raw material used is composed of the union of two types of materials, which include: polyamide, steel cords, fibers of different materials, rubber, among others. According to its destination, some materials of different types are winded in rolls to let them ready for the manufacturing process. Different problems are presented: 1- At the time of separating the raw material of the coating provided by the supplier, in most cases the machine does not generate the proper torque, which causes to tear the film and this can not be used; 2 - No proper tension on the roll is achieved, causing that the cut is not uniform at all points; 3 -The blades used for cutting do not have enough edge, nor are positioned at the correct angle; is difficult to remove the material from the tube due to the difference of tensions in the branches of the drive pulley. The methodology used to calculate and select the drives and power inverters is established on the principles of engineering. In this paper is proposed the improvements in the design of the machine for winding materials for the manufacture of industrial hoses, the modifying of the machine, and is automated the winding process: one main 5 hp engine and a secondary 0.5 hp, a speed variator, two encoders and one PLC.
