Abstract:

The purpose of this study was to compare seventh-grade students' motivation and preference toward text-based programming using Visual Basic, and graphics-based programming using Robolab. Motivation was defined by the My Class Activities questionnaire using the dimensions of interest, challenge, choice, and enjoyment. Preference was determined through team and individual student choice. This study was conducted with 122 students from three 6-week technology education classes. This study examined two hypotheses. First, middles school students will be more motivated when using a graphics-based programming language than text-based as measured by the My Class Activities survey. The second hypothesis for this study was that middle school students preferred using graphic-based programming more than using text-based programming in an introductory experience. Student preference was identified individually and within a team environment.

This study aims to investigate the impact of a robotic environment on the strategies and representations used by students in the interpretation of distance-time graphs. It adopted a methodology based on Design Experiments (Kelly and Lesh, 2000), that is a cyclical process of reflections upon learning and teaching. A constructionist conception, following Seymour Papert (1994), informed the design of the research activities, which were intended to involve students in the creation of innovative solution strategies in the face of challenging problems. Difficulties related to the interpretation of graphs as described in the researches of Beichner (1994), Murphy (1999) and Brown and Crowder (2006) were identified, along with conflicts, such as those discussed by Arzarello e Robutti (2004), Parnafes e Disessa (2004) e Simpson, Hoyles e Noss (2006), experienced within computational environments. For the research activities, we used robotic materials of LEGO Education and the software Robolab was used by students to program the LEGO models they constructed. The activities were realized with one class of 8th grade middle-school students and one class of students from the 1st year of high school in a private school in the city of São Bernardo do Campo in the state of São Paulo. Analyses indicated that the difficulties related to the interpretation of graphs raised in other studies also emerge when students interact in a robotic environment. However, the results also suggest that work with robots, the opportunities to make connections between diverse mathematical representations. Especially the activities involving the construction of their own velocity radar contributed to the overcoming of some of these difficulties, particular as far as the students from the 1st year of high school were concerned
Esta pesquisa tem por objetivo investigar o impacto de um ambiente robótico nas estratégias e representações utilizadas por estudantes na interpretação de gráficos apresentando relações entre distância, tempo e velocidade. Como metodologia de pesquisa utilizamos Design Experiments de Kelly e Lesh (2000), isto é, um processo cíclico das reflexões acerca do ensinar e do aprender. Para o desenvolvimento das atividades buscamos referência na concepção construcionista de Seymour Papert (1994), em que o professor estimula os alunos a criarem soluções inovadoras, a partir de suas conjecturas por meio de desafios. Analisamos as dificuldades quanto à interpretação de gráficos apontadas em diversas pesquisas como Beichner (1994), Murphy (1999) e Brown e Crowder (2006) e também as dificuldades encontradas em ambientes computacionais, tendo como referência Arzarello e Robutti (2004), Parnafes e Disessa (2004) e Simpson, Hoyles e Noss (2006). Optamos por utilizar os materiais de robótica da LEGO Education e o software Robolab 2.0 para programar os modelos construídos. As atividades foram aplicadas em uma turma de alunos da 8ª série do Ensino Fundamental e outra do 1º ano do Ensino Médio, de uma escola privada localizada na cidade de São Bernardo do Campo no estado de São Paulo. Segundo nossas análises, as dificuldades envolvidas na interpretação de gráficos apontadas nas pesquisas anteriores também emergem quando os alunos interagem num ambiente robótico, mas nossos resultados indicam que o trabalho com robôs proporciona oportunidades para criar conexões entre diversas representações. Em especial, a atividade envolvendo a construção de um radar para medir a velocidade contribuiu para a superação das dificuldades, particularmente para os alunos do 1º ano do Ensino Médio

Abstract:

The LEGO® MINDSTORMS® toolkit can be used to help students learn basic programming and engineering concepts. Software that is widely used with LEGO MINDSTORMS is ROBOLAB, developed by Professor Chris Rogers from Tufts University, Boston, United States. It has been adopted in about 10,000 schools in the United States and other countries. It is used to program LEGO MINDSTORMS robotics in its icon-based programming environment. However, this software does not provide debug features for LEGO MINDSTORMS programs. Users cannot test the program before downloading it into LEGO robotics hardware. In this project, we develop a simulator for LEGO MINDSTORMS to simulate the motions of LEGO robotics in a virtual 3D environment. We use ODE (Open Dynamic Engine) and OpenGL, combined with ROBOLAB. The simulator allows users to test their ROBOLAB program before downloading it into the LEGO MINDSTORMS hardware. For users who do not have the hardware, they may use the simulator to learn ROBOLAB programming skills which may be tested and debugged using the simulator. The simulator can track and display program execution as the simulation runs. This helps users to learn and understand basic robotics programming concepts. An introduction to the overall structure and architecture of the simulator is given and is followed by a detailed description of each component in the system. This presents the techniques that are used to implement each feature of the simulator. The discussions based on several test results are then given. This leads to the conclusion that the simulator is able to accurately represent the actions of robots under certain assumptions and conditions.

Full text

Abstract:

Bakgrund De äldre kommer att utgöra en allt större del av befolkningen, vilket kommer att öka behovet av äldreomsorg i samhället. Det kommer dock att bli svårt att rekrytera tillräckligt med personal för att personaltätheten inom äldreomsorgen inte ska minska i framtiden. Moderna arbetssätt och ny teknik kommer att behövas, och ett exempel på ny teknik som börjar komma inom äldreomsorgen är robotar av olika slag. Syfte Syftet var att undersöka kunskapsläget gällande äldre personers inställning till att vårdas av robotar inom äldreomsorgen. Metod En allmän litteraturöversikt har gjorts där 18 artiklar från databaserna Academic Search Elite, PsycInfo och PubMed inkluderades. Dessa har granskats och analyserats med en induktiv ansats för att besvara syftet. Resultat De äldres inställning till robotar skiljde sig åt ganska mycket. Många äldre kunde dock tänka sig att vårdas med robotar, om dessa kan hjälpa till i vardagen, låter den äldre känna sig mera självständig och kan bo kvar i hemmet ytterligare en tid. Många föredrar dock hellre mänsklig kontakt. Ibland kan en robot betraktas som en social varelse, och kan då vara ett sätt att minska den äldres ensamhet. Det är dock viktigt att de äldre är involverade vid införandet av robotar, så att de är införstådda med varför och delaktiga i när och hur införandet sker. Slutsats Både inställning och acceptans av robotar hos de äldre varierar, men många kan tänka sig robotar som en del av sin omsorg utan att det påverkar deras värdighet negativt. Respekt för den äldres val gällande införande av robotar är en del av en värdig omvårdnad. Mer forskning kommer dock att behövas i takt med att robotarna utvecklas och får mer avancerade funktioner. Med dagens teknologi är det tveksamt hur mycket robotar kan bidra till att kompensera för personalbristen. De enda funktioner bland dagens robotar som på allvar kan bidra till detta är kameraövervakning och fjärrkommunikation.

The development of robotics within the elderly care is moving fast forward. There is a wide range of robots for different occasions. By year 2050 it is expected that the worlds older population will be doubled. Robots that can help in the elderly care has thus gotten a political interest hence the demographic development that point to an increase in the proportion of elderly people. This essay will investigate which factors make elderly people accept the usage of robots and how experts in robotics work to develop these robots. The study will be based on data from both elderly people over 65 and experts in robotics and a number of scientific articles have been used for the essay. The results of the study show that factors that are important for older people's acceptance of robots fall under; configuration, knowledge, safety, integrity, perceived ease of use and perceived usefulness. The study shows that experts are currently working well with regard to the elderly.

Abstract:

Denna rapport behandlar automationsmöjligheter inom Saab. Arbetet bedrevs på den civila sidan av Saab i Linköping, mer känd som Saab Aerostructures, som ett examensarbete på kandidatnivå. Flygplansindustrin har i dagsläget en relativt låg grad av automatiserad tillverkning. Detta till följd av de många olika komplicerade moment som utförs samt av den relativt låga produktionstakten. Syftet med det här examensarbetet var att undersöka möjligheterna till att utöka graden av automatiserad tillverkning inom Saab Aerostructures produktion. För att undersöka detta spenderades tid i produktionen för att studera hur arbetet utförs. Med hjälp av undersökningen och samtal med personer inom produktionen togs ett antal tillämpningar fram på uppgifter som kan tänkas automatiseras med en robot. Eftersom Saab har begränsad erfarenhet inom det här området är den här rapporten mer av en förstudie för att sätta bollen i rullning och få företaget att börja integrera nya lösningar för att få en mer effektiv och automatiserad tillverkning av flygplansstrukturer. Arbetet resulterade i att två stycken olika förslag på automationslösningar ges. De två förslagen skiljer sig en hel del åt vad gäller både uppgift och lösning. Det ena föreslås använda sig av en robot som går att arbeta med sida vid sida, utan fysiska avgränsningar i form av stängsel. Den andra lösningen använder en traditionell industrirobot i en vanlig miljö med en skyddsbur. Lösningen med den traditionella industriroboten ser mest lovande ut eftersom arbetet som roboten kommer utföra resulterar i att cirka 40 operatörstimmar per vecka frigörs. Payback-tiden för den investeringen är ungefär 4 år, vilket Saab anser vara överkomligt. Denna lösning kombinerar tre uppgifter: fräsning, tätning och målning som alla utförs på en lastdörr.
This report regards automation possibilities within Saab. The work was conducted at the Aerostructures division of Saab in Linköping, as a final thesis on a bachelor level. The aircraft industry today has a relatively low level of automated manufacturing. The reason for that is that it typically consists of several complicated operations and the production rate is relatively low. The purpose of this thesis was to examine the possibilities to increase the level of automated manufacture in production at Saab Aerostructures. To examine this, some time was spent studying how operations were conducted within production. The information collected combined with discussions within production resulted in a number of applications that might be possible to automate with a robot. Since Saab has limited experience in this field, this report should be considered as a pre-study to put the wheels in motion and initiate discussions regarding new solutions to achieve a more efficient and automated manufacturing process. The work resulted in two different suggested automation solutions. The suggestions differ in both scope and result. One of the suggestions uses a robot that an operator can collaborate with, without any safety fence. The other suggestion uses a traditional industrial robot in a more traditional robot cell. The suggestion of implementing a traditional industrial robot seems like the best alternative to proceed with. Its estimated payback time is approximately 4 years and it has the potential to reduce manual work by 40 hours a week. This solution combines three different operations that are conducted on the same cargo door: milling, sealing and painting.

This thesis describes design and implementation of an approach to the mobile robot localization. The proposed method is based purely on images taken by a monocular camera. The described solution handles localization as an association problem and, therefore, falls in the category of topological localization methods. The method is based on a generative probabilistic model of the environment appearance. The proposed solution is capable to eliminate some of the difficulties which are common in traditional localization approaches.

Abstract:

This master's thesis focuses on representation of geometric information about the surrounding environment for robotic systems. Instead of a common point-cloud based representation, an environment model that stores information about objects described by bounding boxes and planes is proposed. These objects can be obtained from trained object detectors, planar surface detectors, etc. processing data from sensors (e.g. RGB-D camera). The information about the objects (position, etc.) stored in the model is constantly changing according to data obtained from detectors. The environment model is implemented as a module for Robot Operating System. To illustrate and visualize features of the model, a demonstration application was also prepared.

Abstract:

L’elaborato verte sulla simulazione della gestione dei materiali dell’azienda Robopac. Il modello esposto è stato creato tramite il software Arena, il quale permette la riproduzione di una struttura aziendale reale ed è, per questo, uno strumento validissimo per esaminare situazioni critiche, nonché per confrontare alternative progettuali e validarle. Nello specifico, in tale tesi ci si propone di verificare, attraverso un’attenta analisi, come l’azienda Robopac gestisca i materiali nel suo percorso di elaborazione e trasformazione. Per gestione dei materiali si intende il coordinamento degli arrivi, il controllo sulle materie, il trasporto di tali materiali nei magazzini appositi e il successivo spostamento in linea. Questa indagine permetterà di valutare l’efficienza e l’utilizzo delle risorse, le tempistiche delle movimentazioni e l’eventuale creazione di code, così da cercare soluzioni che potrebbero migliorare e ottimizzare le operazioni. Il modello creato con Arena considera i sei codici-prodotto più rappresentativi e rende possibile una riproduzione conforme a ciò che è stato osservato. Inoltre sono analizzati i report forniti automaticamente da tale software e valutati l’utilizzo delle risorse e le giacenze a magazzino. Sarebbe interessante ampliare la simulazione esposta, prendendo in considerazione l’intero numero di codici prodotti, così da poter analizzare la totale gestione dei materiali e considerare eventuali differenze o scostamenti rispetto a quanto svolto in questa tesi. Un ulteriore ampliamento altrettanto valido potrebbe essere quello di coniugare la simulazione della gestione dei materiali con il modello della linea produttiva principale già realizzato con Arena. Ciò permetterebbe una più completa visione dell’azienda e l’indagine della realtà imprenditoriale diventerebbe più ampia, approfondita e dettagliata.

Abstract:

BAKGRUND: Robotrådgivning kan något förenklat definieras som en digital plattform som förser kunder med en automatiserad finansiell rådgivning. Många nya aktörer har börjat tillhandahålla robotrådgivningstjänster och robotrådgivning anses ha potential att förbättra marknaden för finansiell rådgivning. Ur ett konsumentperspektiv leder robotrådgivningen till bland annat sänkta direkta kostnader i form av lägre förvaltningsavgifter. Trots sänkta direkta kostnader och övriga konsumentfördelar har kapitalinflödet till robotrådgivningstjänster inte varit omfattande. Enligt ekonomiska teorier om transaktionskostnader, väljer köpare att inte genomföra köpet av en tjänst om uppfattade transaktionskostnader förenade med själva transaktionen upplevs för höga. Därmed är det av intresse att undersöka hur konsumenter uppfattar transaktionskostnader förenade med robotrådgivningen samt hur detta påverkar intention att använda tjänsten. SYFTE: Syftet med studien är att undersöka hur direkta kostnader respektive indirekta transaktionskostnader påverkar konsumenters intention att använda sig av robotrådgivning. Vidare är syftet att undersöka huruvida respondenter med en liknande intention att använda robotrådgivningstjänster delar några gemensamma drag. GENOMFÖRANDE: Data till studien har samlats in med hjälp av enkätundersökning. Enkäten har besvarats av 77 personer. För att analysera statistiska samband mellan de olika oberoende variablerna och den beroende variabeln intention har vi genomfört en multipel regressionsanalys. För att vidare analysera den insamlade datan och få ännu djupare insikter i hur respondenterna ställer sig i förhållande till robotrådgivningen har vi genomfört klusteranalys. SLUTSATS: Enligt vår studie har variablerna förtroende och mänsklig kontakt ett statistiskt signifikant samband med intentionen att använda robotrådgivning. Enligt klusteranalysen kan dessutom två konsumentprofiler urskiljas med utgångspunkt i intention att använda robotrådgivning. Direkta kostnader, vilka har undersökts med hjälp av variabeln kostnad, har inte visats ha något större inverkan på konsumenternas inställning till robotrådgivning, varför hybridlösningar enligt vår mening skulle kunna vara en möjlig lösning för att minska konsumenternas uppfattade transaktionskostnader och på det sättet öka intentionen att använda robotrådgivningstjänster.
BACKGROUND: Robo-advisory can be defined as a platform which provides customers with an automated financial advisory. A large number of new and already existing financial institutions have started providing robo-advisory services and robo-advisors are considered to have the potential to improve the market of financial services. Among other things, robo- advisory leads to decreased direct costs for consumers in terms of lower management fees. Despite the reduced direct costs and other consumer benefits, the capital inflow to robo- adivosory services has not been substantial yet. According to the economic theories in the field of transaction costs, a buyer is not going to conduct a purchase of a service if perceived transaction costs associated with the transaction itself are too high. Thus, it is essential to examine how consumers perceive transaction costs associated with robo-advisory and how that affects consumers intention to use robo-advisory-services. PURPOSE: The purpose of this study is to examine how direct costs and indirect transaction costs affect consumers intention to use robo-advisory. Furthermore, the purpose of this study is to examine whether consumers with a similar intention to use robo-advisory services, share any other characteristics. IMPLEMENTATION: Data for our study has been collected via survey. The survey has been answered by 77 people. To analyze possible statistical relationships between the dependent variables and the independent variable intention, we have conducted a multiple regression analysis. In order to further analyze the collected data and gain even deeper insights into how respondents stand in relation to robo-advisory, cluster analysis has been conducted. CONCLUSION: According to our results, only variables trust and human contact have a significant statistic relationship with the intention to use robo-advisory. Furthermore, by means of cluster analysis we have been able to distinguish two consumer profiles based on the dependent variable intention. Direct costs, in terms of the variable cost, have not been shown to have any substantial impact on consumers attitude towards robo-advisory. Hence, hybrid- solutions could, in our opinion, be a possible solution in order to reduce consumers perceived transaction costs, and further increase the intention to use robo-advisory.

This thesis presents possibilities of 3D point cloud and true colored digital video fusion that can be used in the process of robot teleoperation. Advantages of a 3D environment visualization combining more than one sensor data, tools to facilitate such data fusion, as well as two alternative practical implementations of combined data visualization are discussed. First proposed alternative estimates view frustum of the robot's camera and maps real colored video to a semi-transparent polygon placed in the view frustum. The second option is a direct coloring of the point cloud data creating a colored point cloud representing color as well as depth information about an environment.

Abstract:

Denna uppsats handlar om medelålders personers inställningar till robotar i vården. Utmaningen är att fylla gapet som skapas mellan ökandet av äldre och minskandet av vårdgivare. Robotar i hemmet ska fungera som ett hjälpmedel för äldre personer där de ska kunna bo själva längre och även känna självständighet. Uppsatsen undersöker hur personer mellan 40 och 60 år ser på robotar i hemmet och om de hade kunnat tänka sig ha en sådan hemma när de blir äldre. En jämförelse görs mellan 20-40 åringar från en tidigare studie som genomfördes för ca 15 år sedan och dagens 40-60 åringar för att ge svar på frågan: Har synen på robotar och inställningen till dessa förändrats över tid sedan den sista undersökningen år 1998? Vilka mönster finns det – likheter och skillnader?

Abstract:

This thesis is a part of a larger project included in the European project, AFFIX. The reason for the project is to try to develop a new method to assemble an aircraft engine part so that the weight and manufacturing costs are reduced. The proposal is to weld sheet metal parts instead of using cast parts. A machine vision system is suggested to be used in order to detect the joints for the weld assembly operation of the sheet metal. The final system aims to locate a hidden curve on an object. The coordinates for the curve are calculated by the machine vision system and sent to a robot. The robot should create and follow a path by using the coordinates. The accuracy for locating the curve to perform an approved weld joint must be within +/- 0.5 mm. This report investigates the accuracy of the camera calibration and the positioning of the robot. It also brushes the importance of good lightning when obtaining images for a vision system and the development for a robot program that receives these coordinates and transform them into robot movements are included. The camera calibration is done in a toolbox for MatLab and it extracts the intrinsic camera parameters such as the distance between the centre of the lens and the optical detector in the camera: f, lens distortion parameters and principle point. It also returns the location of the camera and orientation at each obtained image during the calibration, the extrinsic parameters. The intrinsic parameters are used when translating between image coordinates and camera coordinates and the extrinsic parameters are used when translating between camera coordinates and world coordinates. The results of this project are a transformation matrix that translates the robots position into the cameras position. It also contains a robot program that can receive a large number of coordinates, store them and create a path to move along for the weld application.

The development of autonomous robots has made a significant progress and first personal robots for common use start to appear. To use this robots, we need to develop applications and user interfaces to interact with them. The goal of this project is to make a universal interface for robot remote control. This work focuses on robots based on the ROS platform. This gives the final application a potential of use on other robotic projetcs running on ROS. The designed remote interface accomplishes two main purposes. The first is to show important data in a context of a 3D scene to help user understand the state of the controlled robot. And the second goal is to allow the user execute some basic manipulation with the robot. The final application was successfully adapted and tested on experimental robots Care-O-Bot and Turtlebot.

Abstract:

This work's aim is movement detection in the environment of a robot, that may move itself. A 2D occupancy grid representation is used, containing only the currently visible environment, without filtering in time. Motion detection is based on a grid-based particle filter introduced by Tanzmeister et al. in Grid-based Mapping and Tracking in Dynamic Environments using a Uniform Evidential Environment Representation. The system was implemented in the Robot Operating System, which allows for re-use of modules which the solution is composed of. The KITTI Visual Odometry dataset was chosen as a source~of LiDAR data for experiments, along with ground-truth pose information. Ground segmentation based on Loopy Belief Propagation was used to filter the point clouds. The implemeted motion detector is able to distiguish between static and dynamic vehicles in this dataset. Further tests in a simulated environment have shown some shortcomings in the detection of large continuous moving objects.

The presented diploma thesis deals with the design and construction of a simple humanoid robot with two arms attached to a torso. The work was solved as a team project of two authors. Therefore, only the construction of the arm, which is inspired by the kinematics of the human arm is described in more detail. Its construction was the task of the author. An important part of the work is the selection of drives and sensors for the operation of the mechanism. Furthermore, the work presents the procedure of creating a kinematic model of the arms to solve the forward and inverse kinematics problem. For the possibility of motion control, the control of the control unit in Simulink was designed and the drive control was created.
