- Evaluation, optimization and simulation of the production of a Tesla turbine and Stirling motor in a reconfigurable manufacturing system(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2012-12-01) Rivero Pérez, Luis Fernando; Rivero Pérez, Luis Fernando; 389903; Guedea Elizalde, Federico; Jiménez González, Ricardo; Cortés Ramírez, Jorge Armando; Cárdenas Alemán, Eduardo; Escuela de Ingeniería y Tecnologías de Información Programa de Graduados; Campus MonterreyEmerging economies and new ways of doing business are changing the world in a dramatic manner, these changes suggest that new competitive advantages must be created within companies to be able to develop customized products and cost effective manufacturing systems. Reconfigurability has been an issue in computing and robotics for many years. In general, reconfigurability is the ability to repeatedly change and rearrange the components of a system in a cost-effective way. In this thesis two products are manufactured in a Reconfigurable Manufacturing System (RMS) that has the ability to rearrange the conveyor belts because these were manufactured as modules. This research shows the evaluation and improvement of production process of a Tesla turbine and the creation of the production process of a Stirling motor in a Reconfigurable manufacturing system. Also, the two production processes were simulated in “Plant Simulation”. The methodology used to reach the objectives is based in the development of three main stages. The first stage “Obtaining of operations times” has the purpose of get the times of each operation involved in the production process. The second stage “Definition of the Process Flow” has the purpose of define the number of pallets, their contents and their flows in the manufacturing cell. Finally, the stage “Calculation of production parameters” has the purpose of calculate cycle times, production rates, utilizations can compare the improvement in relation with old production process or if the product has never been manufactured to can obtain good results and compare them in the future with others production process. For the Tesla turbine the reduction of the cycle time in percentage was 13.21%, therefore there was an increase in the production rate in 13.21%. Also, every station increased its utilization with the new production process. The production process of a Stirling motor was created using the same configuration that was used with the Tesla turbine and the cycle time obtained was 37 minutes and 45 seconds approximately.
- Development of a Language for Robot-Based Assembly Domain -Edición Única(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2011-12-01) Villegas Hernández, Yasmín Sarahí; Guedea Elizalde, Federico; Jiménez Pérez, Guillermo; Cabeza Azpiazu, Luis Vicente; Tecnológico de Monterrey, Campus Monterrey; Rodríguez González, Ciro ÁngelThis thesis research presents the implementation of a programming language to describe a Robot-based assembly and welding domain using tools as planners and parser in order to generate plans for robots. This programming language is used to describe an automated robotic-workcell. In this thesis, using this language, a plan can be generated, which is parsed in order to obtain a robot program for the pick-and-place task. The idea is to use the plan written in a high-level-language in order to get a generic-lowlevel-language robot program for pick-and-place task, using a planner and a parser. The generation of robot program works as follows: First, the planner generates a plan using the language developed. Second, the parser changes the high-level-language plan to a generic-low-level-language. Some examples are provided of the tests performed in this thesis. The language developed in this thesis was tested in order to prove their functionality by building some sub-assembly goals. Furthermore, the functionality of the other components of the system were tested separately and in combination with the language developed.
- Stereovision Feedback and Fuzzy Control for Autonomous Robot Navigation-Edición Única(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2010-12-01) Aristeo Hernández Martínez; Guedea Elizalde, Federico; Sedas Gersey, Sergio; Ramírez Cadena, Miguel de Jesús; Tecnologíco de Monterrey, Campus Monterrey; Casañon Ávila, Gerardo AntonioThe main objective of this thesis is the implementation of an autonomous robot that is capable of following a road w i t h the use of a stereocamera. The use of vision i n 3D is a trend i n many vision applications, and we would like to adopt it for autonomous vehicle navigation. Road following requires two crucial steps: the road recognition and the control of the speed and steering of the vehicle. To reach controllability i n these type of robots it is necessary to detect the road and make the image processing to calculate the manipulations needed to keep the robot i n the desired position and path. It can be said that vision systems are a very important factor i n the development of autonomous vehicles because they are the sensors of the robot; therefore, the image processing needs to be done on time i n order to detect the road and let the entire system to be controllable. Through this thesis, various techniques i n different areas such as road detection, image processing and fuzzy control theory will be examined i n order to achieve the objective.
- Remote manufacturing using distributed systems(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2009-12-01) Trasfí Covarrubias, Luis Carlos; Trasfí Covarrubias, Luis Carlos; 257653; Guedea Elizalde, Federico; Rodríguez González, Ciro Ángel; Siller Carrillo, Héctor Rafael; Tecnológico de Monterrey, Campus Monterrey; Rodríguez González, Ciro ÁngelGlobalization is a trend for companies to expand markets and seeks to have a global dimension that surpasses national borders. It is necessary to promote the development of communication and transport which involves the interconnection of decentralized networks computers connected to the manipulation of different machines with a world scope. So that it exists decentralized interconnection of networks of computer for the manipulation of different machines and the realization of modular and reconfigurable of manufacture systems can be worked using open control systems and distributed systems. An Open System has the capacity to program and to work with the software in several different platforms. Distributed systems consist of shared heterogeneous resources that are based on different platforms, architectures of hardware, software and programming languages in different places and belonging to a network that uses a publicly available specification for achieving a specific task. This thesis work consists on a mechanism used by standard middleware software for building object-oriented client–server applications in C++ language, on Windows operating System, on low cost commercial equipment communicating using TCP/IP protocol. This mechanism has two dedicated servers: one for video capturing and the other for the movement, speed and direction of axes. Furthermore each server has different application service that can be communicated independently in order to send specific information that can be added depending on the customer requirements. The results obtained with the set of experiments demonstrate that the low cost commercial equipment with communication to a computer has the advantage to have the vision for the manufacture of a piece by the communication with a computer, besides getting the control of the movement of the different machine axes. This application can be used in heterogeneous environments that access a remote object as accessing an ordinary, local C++ object. The main goal for using a distributed system is to show the transparency, openness, reliability, performance and scalability.
