Automatický tester HMI / HMI automatic testerLang, Stanislav January 2011 (has links)
This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications.

Obslužný program pro colony-picking robot / Control Program for Colony-picking RobotMatějka, Lukáš January 2012 (has links)
From an overview of most commonly used kinematic conceptions of robotic manipulators, the conception of Cartesian robot was identified as the most suitable for the given task of colony picking. A control system consisting of two modular parts has been designed for the colony picking robot. ColonyCounter module is a set of image processing libraries for identification of microbial colonies in image data and precise localization of individual colonies. This has been achieved by combination of multiple methods, most importantly connected components labelling and Hough circular transform. The second module – ColonyPicker – utilizes output of ColonyCounter module to plan the picking and placing of colonies. Subsequently it controls the transfer process itself using an innovative task planning and executing system.

[pt] DESENVOLVIMENTO E CONTROLE DE UM ACOPLADOR ELÁSTICO BASEADO EM ELASTÔMEROS PARA SEA / [en] DESIGN AND CONTROL OF AN ELASTOMER-BASED ELASTIC COUPLING FOR SEAFELIPE REBELO LOPES 02 October 2023 (has links)
[pt] Questões de segurança têm sido fatores cruciais para que robôs se tornem
aptos a trabalhar em colaboração com seres humanos. Esse esforço envolve
um controle de força mais refinado e uma certa flexibilidade nas juntas para
que a adaptação dos robôs ao ambiente real e às atividades comuns dos seres
humanos seja efetiva. Uma das tecnologias com esse objetivo é o Atuador
Elástico em Série (SEA - Series Elastic Actuator), que apresenta um bom
desempenho para controle de força, tolerância a impactos causados por agentes
externos, baixa impedância, e a redução de vibrações mecânicas. Em um SEA,
um elemento elástico passivo é adicionado entre o motor e o elo acionado,
a fim de gerar flexibilidade. Este elemento pode ser uma mola, ou outro
elemento deformável com flexibilidade caracterizada por sua geometria e pela
elasticidade do material utilizado. Esta tese propõe um Atuador Elástico em
Série Baseado em Elastômero (eSEA), cuja flexibilidade é obtida a partir de
um elastômero depositado entre dois elementos metálicos: um interno acoplado
ao atuador, e o outro externo acoplado ao elo. O eSEA foi projetado e avaliado
por software de CAD e Elementos Finitos, com o intuito de obter a flexibilidade
desejada para a aplicação. Foram produzidas duas versões do eSEA, com
duas durezas diferentes: 10 e 55 Shore A. Testes estáticos com células de
carga foram executados para caracterizar a rigidez dos eSEA. Os eSEA foram
instalados em manipuladores robóticos especialmente desenvolvidos para essa
tese. Experimentos compararam o desempenho das técnicas de controle com
e sem a influência dos eSEA, mostrando que o uso dos eSEA diminuiu os
erros de posicionamento do manipulador e possibilitou o controle de força sem
a necessidade de sensores específicos. A fim de criar um modelo para que a
estimativa do torque seja mais precisa a partir do eSEA, foram realizadas
técnicas de identificação para estimar uma função de transferência que melhor
representa o alongamento da borracha. E combinados com modelos NARX e
NARMAX do erro de estimativa, gerou-se um modelo híbrido para o elemento
elástico no qual soma-se a função de transferência com o erro modelado. / [en] Safety issues have been crucial factors for robots to become able to work
in collaboration with humans. This effort involves more refined force control
and a certain flexibility at the joints, for the robots to better adapt to real
environments and common human tasks. A technology with this objective is
the Series Elastic Actuator (SEA), which presents good performance for force
control, tolerance to impacts caused by external agents, low impedance, and
dampening of mechanical vibrations. In an SEA, a passive elastic element is
added between the motor and the driven link, in order to generate a desired
flexibility. This element can be a spring, or else another deformable element
with flexibility characterized by its geometry and material elasticity. This thesis
proposes an Elastomer-Based Series Elastic Actuator (eSEA), whose flexibility
is obtained from an elastomer deposited between two metallic elements: an
internal element attached to the actuator, and an external element attached to
the link. The eSEA was designed and evaluated by CAD and Finite Element
software, in order to obtain the desired flexibility for the application. Two
versions of the eSEA were produced, with two different hardnesses: 10 and
55 Shore A. Static tests with load cells were then executed to characterize
the stiffness of the eSEA. The eSEA elements were installed on robotic
manipulators especially developed for this thesis. Experiments compared the
performance of control techniques with and without the influence of eSEA,
showing that the use of the eSEA reduced manipulator positioning errors
and enabled force control without the need for specific sensors. In order to
create a model for more accurate torque estimation from eSEA, identification
techniques were performed to estimate a transfer function that best represents
the rubber elongation. And combined with NARX and NARMAX models of
the estimation error, a hybrid model was generated for the elastic element in
which the transfer function is added together with the modeled error.
