The search for alternatives that facilitate the care and feeding of a pet has created the need to apply current technological development in this type of application, since pet owners have restricted time to stay with them due to their daily duties, studies, work or carelessness. In the region, acquiring an automatic device that dispenses food and water in the same equipment and includes remote monitoring through an app on a smartphone is challenging and can be expensive. Therefore, this work presents the development of an automatic device based on MQTT (Message Queuing Telemetry Transport) to dispense food and water for pets, capable of being monitored and controlled through a mobile device. By integrating multiple technologies and tools such as: programming languages, sensor and actuator management, Raspberry Pi, Arduino, CAD (Computer-Aided Design) design and 3D printing, this IoT (Internet of Things) solution allows to implement an innovative prototype that contributes to improve this social problem not only in our country but throughout the region. The functionality tests validate that the developed device has a short response time and that it allows pet owners greater independence and peace of mind.

The article is devoted to the problems of simulation of the working process of a truck-mounted crane using modern computer-aided design systems and applications for engineering calculations. Currently, analytical methods are mainly used to model the operation of manipulator technology, such as “manual” compilation and solution of Lagrange equations of the second order, or even simpler evaluative calculations based only on basic concepts of theoretical mechanics. However, such objects consist of many parts that are in a complex rotational motion and contact interaction with each other. If such complex systems are modeled by the indicated analytical methods, one has to introduce a number of assumptions that greatly simplify the mathematical model. The level of its adequacy is low. Also recently, numerical methods for modeling mechanisms that are implemented through programming languages by using a detailed description of the process under study are often used abroad. An alternative to these methods is the use of computer-aided design systems in which numerical methods are built-in at the core level of the program and require setting the basic geometric, dynamic and kinematic parameters of the mechanism and the environment, after which they can calculate the functioning parameters of the object under study. The process of creating a simulation model of a truck mounted crane, which is an analogue of an existing laboratory setup, has been considered. To do this, a 3D model of the manipulator in the SolidWorks CAD environment has been developed. The creation technique and the main features of the obtained simulation model have been described

Abstract In the paper we present a general solution for handling the large matrices. This solution is general because of the wide use of the matrix based approach in problems concerning numerical methods, experimental mechanics, computational mechanics, CFD, computer aided design, economical problems, etc. Some of the major advantages of this solution are: 1. lack of requirements regarding the use of some high-performance computers, the constraints being connected to the size of the hard-disk (at present increasing and being cheaper); 2. Windows operating system may be used but it is not absolutely necessary; 3. it represents an interface between the programming languages; 4. it can easily be used for development of multi-language software applications; 5. applicability in all the domains which use, at the logical level, ‘matrices’ (mathematics, engineering, economics); 6. there are no constraints regarding the use of ‘classic’ solutions techniques; 7. it is easy to implement in software applications already written; 8. data type used as interface may easily be modified in order to be adapted in an optimum way to the current application to be developed. By the use of this solution we solved a series of computer problems and ‘dedicated’ applications in some areas like: Mathematics, Experimental Mechanics, Computational Mechanics, Physics, etc.

The acquisition of knowledge in computer programming has been a new skill required by the most diverse academic backgrounds. It is no different for students and professionals using CAD (computer-aided design) software. There are several programming paradigms, and the use of textual programming languages like Python had been the most appropriate and has shown good results. This chapter presents the results of a study intended to understand the difficulties of learning computer programming in Python language, aimed at architects, and how the instructional design 4C/ID model can be used to overcome some of these difficulties; it also analyses the effects of this learning environment on the acquisition and transfer of programming knowledge.

This paper describes the structure and operation of a low-cost computer aided design system for press tool design (CAPTD). The system is a collection of integrated industry standard microcomputer packages and purpose-built programs. The packages include AutoCad 11, for the input of workpiece geometry and the output of the press tool part and assembly drawings, and dBase IV for the decision support, the selection of press tool components and generating output reports. A purpose built ‘C’ program is also developed for the layout and nesting of the workpiece. The system is driven by a set of press tool design rules implemented in both the dBase IV and ‘C’ programming languages. The system is developed to run on 80386SX or higher based IBM-compatible microcomputers.

Abstract The technological development of the last decades have been able to push human to develop their needs, so a way to new demands were opened and this can lead to a complexity problem. Thereby, a good interoperability between the product design activities can lead to the possibility of ensuring a promising satisfaction to all requirements. However, the major problem is the enormous discontinuity between them. Indeed, each one treats the product from its point of view without recourse to the requirements defined by others. This paper is interested in the collaborative work that brings together the system engineer, who deals with the system from a global view, and the designer, who is a specialist in the detailed design, in order to validate requirements. A new methodology has been proposed to define the role of each one in the design process. This methodology focuses on the product development cycle from the analysis of needs to the validation phase. This obviously requires interoperability between the two domains of Model Based System Engineering (MBSE) and Computer Aided Design (CAD). Based on a pedal bicycle case study which is an industrial mechatronic product, the proposed methodology will be illustrated for validation and highlighting its advantages and limitations.

Despite the accelerated development of computer technology, programming languages and methods in recent years, computer-aided design of open-die forging on presses is still not widespread due to weak formalization of the subject area. Therefore, the developers of relevant computer-aided systems have to put “approximate” algorithms and programs into the systems for solving technological problems. As a result, they provide users with the ability to adjust design concepts by a graphic dialogue. The paper describes a mechanism of interactive communication between the user and the computer-aided design system of shaft forging on presses, which was developed at the Institute of Engineering Science of the Russian Academy of Sciences (Ural Branch). This system provides wide opportunities for making necessary adjustments in a forging drawing and a forging process map. This ensures obtaining necessary design and process documentation suitable for using in the production process, even when the algorithms and programs are imperfect. Moreover, it significantly facilitates the implementation of the system at various enterprises.

This article shows the three-dimensional (3D) modelling and virtual reconstruction of the first mechanical calculating machine used for accounting purposes designed by Blaise Pascal in 1642. To obtain the 3D CAD (computer-aided design) model and the geometric documentation of said invention, CATIA V5 R20 software has been used. The starting materials for this research, mainly the plans of this arithmetic machine, are collected in the volumes Oeuvres de Blaise Pascal published in 1779. Sketches of said machine are found therein that lack scale, are not dimensioned and certain details are absent; that is, they were not drawn with precision in terms of their measurements and proportions, but they do provide qualitative information on the shape and mechanism of the machine. Thanks to the three-dimensional modelling carried out; it has been possible to explain in detail both its operation and the final assembly of the invention, made from the assemblies of its different subsets. In this way, the reader of the manuscript is brought closer to the perfect understanding of the workings of a machine that constituted a major milestone in the technological development of the time.
