Design And Construction

The use of algorithms is a necessary activity for the design and construction, of any mobile robot. This study proposes an algorithm for future farm applications. Fertilization is an aspect that represents a third of the production costs. Robotics applied to agriculture, although in Mexico it is in the early stages of its development, the productive greenhouses are progressively automatized. Therefore, it is necessary to propose new automation strategies in the sector. As part of a stage of design and modeling of a virtual robot, this project proposes an algorithm of a 3D virtual robot prototype that allows visualizing and positioning in the 2D plane and thus having preliminary simulations for the subsequent construction of the Robot prototype.

Product And Process

Abstract How can the manufacturability of different product design alternatives be evaluated efficiently during the early stages of concept exploration? The benefits of such integrated product and manufacturing process design are widely recognized and include faster time to market, reduced development costs and production costs, and increased product quality. To reap these benefits fully, however, one must examine product/process trade-offs and cost/schedule/performance trade-offs in the early stages of design. Evaluating production cost and lead time requires detailed simulation or other analysis packages which 1) would be computationally expensive to run for every alternative, and 2) require detailed information that may or may not be available in these early design stages. Our approach is to generate response surfaces that serve as approximations to the analyses packages and use these approximations to identify robust regions of the design space for further exploration. In this paper we present a method for robust product and process exploration and illustrate this method using a simplified example of a machining center processing a single component. We close by discussing the implications of this work for manufacturing outsourcing, designing robust supplier chains, and ultimately designing the manufacturing enterprise itself.

Design And Construction

This article presents the design and construction of a mobile robot (E-BOT) both in the hardware and in the software part, which works as a support tool for teaching processes and allows to consolidate learning in related topics. a Programming having as its scope repetitive structures, this through a series of previously constructed learning elements. E-BOT has a series of actuators (Led, oled, servomotor, motors) and sensors (ultrasound and reflective light) which are controlled by means of Arduino that allow an easy interaction of EBOT with the real world. Additionally, the construction of a verification software is carried out that allows us to validate the correct operation of all the modules built.

Garbage is a problem that must be handled properly. Currently, technology and information are also used to assist waste management, namely the Smart Trash Bin. In this research, the design and construction of the Mobile Smart Trash Bin is carried out. The design of this smart trash bin not only has an automatic function to open and close the trash can, but also has a mobile function that allows the trash can to move closer to the person who is going to throw garbage. A smart trash bin mobile robot system is designed using a photodiode sensor as a line reader (track robot) and a servo motor is used to open and close the trash can. In addition, Bluetooth HC05 is used to activate the robot via voice commands from an android smartphone. The mobile robot smart trash bin runs according to the system designed.  Sampah merupakan permasalahan yang harus mendapatkan penangan yang tepat. Saat ini, teknologi dan informasi juga digunakan untuk membantu pengelolaan sampah yaitu dengan adanya tempat sampah pintar (Smart Trash Bin). Pada penelitian ini dilakukan perancangan dan pembuatan Mobile Smart Trash Bin. Rancangan smart trash bin ini tidak hanya memiliki fungsi otomastiasi buka tutup tempat sampah tetapi juga dilengkapi fungsi mobile yng memungkinkan tempat sampah untuk bergerak mendekati orang yang akan membuang sampah. Dirancang suatu sistem mobile robot smart trash bin dengan menggunakan sensor fotodioda sebagai pembaca garis (track robot), motor dc sebagai penggerak mundur maju robot dan motor servo digunakan untuk membuka dan menutup tempat sampah. Selain itu, Bluetooth HC05 digunakan untuk mengaktifkan robot melalui perintah suara dari smartphone android. Mobile robot smart trash bin berjalan sesuai dengan sistem yang dirancang.

Autogyro principles and theory are well known and only the practical aspects of design and construction of the smallest of autogyro aircraft will be considered on this occasion. Also, at this stage, it would be inappropriate to be specific about prices of such aircraft owing to the difficulty of estimating production costs. Tare weights, however, may provide some clues as to costs.In the “thirties” the autogyro had been brought to quite a high standard of performance, mainly through the pioneering and development efforts of one man, Senor Juan de la Cierva.During those years many ideas, which would today be regarded as novel, had been tried. Jump-start, pusher engines and tricycle undercarriages are not new.

В статье приведены результаты статистического анализа средних тунцеловных судов, позволившие определить диапазон изменения их основных элементов, выбрать судно «прототип» и провести ряд вариационных исследований по определению влияния основных элементов тунцеловного судна (изменении расчетной длины и ширины) на его качества. Ошибочно выбранные главные размерения на ранних стадиях проектирования приводят к финансовым и временным затратам в процессе проектирования и постройки судна. В связи с этим, важно на ранних стадиях проектирования для выбора оптимальных размерений, иметь показатели качеств, для каждого из выбранных габаритов судна. Для рассматриваемых вариантов судна построены теоретические чертежи, кривые элементов теоретического чертежа и проведено их цифрование. По результатам исследований мореходных качеств (проверка остойчивостии и оценка буксировочного сопротивления), а также анализа частот собственных колебаний корпуса по первому тону, при изменении расчетных длины и ширины судна, сделаны соответствующие выводы. The article presents the results of a statistical analysis of medium-sized tuna vessels, which made it possible to determine the range of changes in their main elements, choose a prototype vessel and conduct a series of variational studies to determine the influence of the main elements of a tuna vessel (change in the calculated length and width) on its quality. Incorrectly chosen main dimensions in the early stages of design lead to financial and time costs during the design and construction of the vessel. In this regard, it is important at the early stages of design to select the optimal dimensions, to have quality indicators for each of the selected dimensions of the vessel. For the variants of the vessel under consideration, theoretical drawings, curves of the elements of a theoretical drawing were constructed and digitized. Based on the results of studies of seaworthiness (stability check and assessment of towing resistance), as well as analysis of the frequencies of natural vibrations of the hull by the first tone, when changing the calculated length and width of the vessel, the corresponding conclusions were drawn.
