Upgrading Design: A Mechatronic Investigation into the Architectural Product MarketGaboury, Matthew 13 April 2010 (has links)
It was first stated 200 years ago, and reiterated numerous times since, that "architecture is frozen music". While this romantic analogy sufficiently satisfies many in the realm of architecture, it actually is a sad way of defining an idea so inherently lively. Goethe's quote conjures up the notion of a world that is silent, one in which we can see the notes but never hear the music because we are trapped by stasis in time. Like the note admired on a piece of paper, architecture in this world is static regardless of the changing conditions around it.
What if the "frozen" part could be removed from this concept, and the element of time could play an active role in the built environment? An architecture that can exist in a sense of time is one in which the musical note can be played. Through the ability to change with time and be changed by time architecture can directly respond to its inhabitants, environment, and contextual factors. A rich melody of interaction can then be initiated in which the built world can talk back.
Naturally, the first point of this contact would be the building's facade, and it is here that there is the greatest opportunity to reach the largest audience. The outer "face" of a building has always been a feature of significance for both designer and customer. For centuries the ornamental features of a building were what distinguished its purpose and place in society. From the elaborite pediments of the Greeks to the inticatly carved reliefs of the Itailians, the ornament of a structure told a static story about the creators and inhabitants of the structure. Now, the technology is available to make this aspect of architecture talk to us by becoming a dymanic, interactive, and kinetic component.
In order for this facade system to transcend the boundries of conventional architecture it must utilize precocious architectural means, methods, and materials. These new communication systems include, but are not limited to, touch, light, sound, and electromagnictic fields. As any of these stimuli are precieved by the facade, it can have the ability to react proportional to the input. Esentially, the facade system will be able to customize itself depending on the conditions presented. Similar to a computer operating system, the new facade will provide a generic mass producible platform that can be individualized by it user. The users of this system may be the architect, client, occupant, viewer, environment, regional context, technologic connection, or global community, depending on the specific installation. And most importantly, both the user and the facade have the capacity to be changed or altered at any time, meaning that the fundamental characteristics of the project will never be frozen. In this manner, the new architectural ornament will go beyond the static nature of its predecessors and become one that the viewer can actively communicate with.

Learning Mechatronics : In Collaborative, Experimental and International settingsGrimheden, Martin January 2002 (has links)
The academic subject of mechatronics has been definedpreviously in numerous publications. This study aims atanalyzing mechatronics by using categories developed within theeducational science of Didactics. The result of the analysis,that relies on data from mechatronics education at KTH andother universities, shows that the identity of mechatronics canbe described as thematic, and the legitimacy as functional,which gives implications for the questions of communication andselection: what should be taught, and how. This is combinedwith a study of the evolution of the subject of mechatronics,where it is possible to see the gradually changing identity,from a combination of a number of disciplinary subjects to onethematic subject. The first part of the thesis concludes that mechatronics isautonomous, thematic and functional. Teaching and learningmechatronics according to the identity and legitimacy of thesubject benefits from collaborative, experimental andinternational settings. The functional legitimacy todayrequires the collaborative and the international setting,meaning that the mechatronics employer requires these skillswhen employing a mechatronic engineer. Further, an exemplifyingselection requires the experimental setting, in particular whencomparing a representative selection with the reproduction ofknowledge, and an exemplifying selection with the creation ofknowledge. To conclude, there are a number of important aspects to takeinto account when teaching and learning mechatronics. Three ofthese aspects, collaborative, experimental and internationalare suggested as important, and also a direct consequence ofthe identity of mechatronics. This thesis shows that thesethree aspects are indeed possible to integrate intomechatronics education, which will benefit greatly fromthis. / QC 20100609

VelOn - The detachable bicycle motor / VelOn - Den avtagbara elcykelmotornElander, Filip, Rönnberg, Cecilia January 2019 (has links)
Electric bikes have become a popular means of transportation over the years. This report examined whether or not it is plausible to upgrade old bicycles to electrical bikes, thereby, using the already existing bicycles and avoiding the need of unnecessary manufacturing. A prototype of the mountable motor was designed and manufactured. The device consisted of two units, a mounting unit and a motor unit. A controller was connected to the motor and could be placed on the handlebar. The controller both enabled control and monitoring of the power given to the motor. The prototype’s durability, potential velocity and control system were tested to answer the research questions and give recommendation to further developments of the project. No major malfunctions were found in the construction after testing. For a voltage of 12V and a payload of 22kg, the bicycle obtained a top speed about 3m/s. The control system gave a smooth transition between velocities with hardly any noise to the signals. / Den elektriska cykeln har under åren blivit ett populärt transportmedel. Denna rapport kommer att undersöka huruvida det är rimligt att uppgradera traditionella cyklar till elcyklar. Istället för att nyproducera elcykelramar kan redan befintliga cyklar användas. En prototyp av en monterbar och avtagbar cykelmotor byggdes. Prototypen bestod av två enheter, en infästningsenhet och en motorenhet. Motorenheten var kopplad till ett kontrollsystem som gick att fästa på styret. Via kontrollsystemet kunde man både kontrollera och övervaka effekten från motorn. Prototypens tålighet, potentiella hastighet och kontrollsystem testades för att besvara forskningsfrågorna och lägga en grund för vidareutveckling av konceptet. Det hittades inga allvarliga brister eller skador av konstruktionen efter testerna. Vid en motorspänning på 12V och en last på 22kg så nåddes en maxhastighet på lite över 3m/s. Kontrollsystemet gav en jämn övergång mellan de olika hastigheterna, utan påverkande brus i signalerna.

Motorized tensioner systemfor prosthetic handsHardell, Felix, Tjomsland, Jonas January 2018 (has links)
Modern research in prosthetic devices and other assistivetechnologies are constantly pushing boundaries. Whilethe technology is impressive, it is still inaccessible for thegreater part of the people in need of it. Advanced devicesare often extremely expensive and require regularly maintenancefrom professionals. Enabling the Future is a globalnetwork of volunteers and was founded to face these problems.They design and 3D-print mechanical prosthetics forpeople in need all over the world.Most of the designs used by Enabling the Future are purelymechanical and do not implement motors. The purposeof this thesis was to take a new approach to the designand construction of low-cost motorized prosthetic hands.By distancing all the electronic components from the hand,including the motor, the project aimed to create a devicecompatible with all current designs of the Enabling the Futurecommunity.To conceptualize this approach a demonstrator was constructedand tested. It utilized a muscle sensor which allowedusers to control the hand by tightening their muscles.The distance between the electronic components andthe prosthetic hand measured approximately one and a halfmeters and still transfered enough force, from the motor tothe hand, to deliver an adequate grip strength. / Modern forskning inom protestillverkning och andrahandikapphjälpmedel gör kontinuerligt stora framsteg. Trotsatt tekniken är imponerade är den fortfarande otillgängligför den största del människor som behöver den. Avanceradehjälpmedel är ofta extremt dyra och kräver kontinuerligtunderhåll från yrkesverksamma. Enabling the Future,ett globalt nätverk av volontärer, grundades för att utmanadessa problem. De konstruerar och tillverkar 3D-skrivnamekaniska proteser för människor med behov över hela världen.De flesta konstruktioner som används av Enabling the Futureär helt mekaniska och använder inga motorer. Syftetmed detta kandidatexamensarbete var att med nya tillvägagångssättkonstruera en billig motoriserad handprotes.Genom att placera all elektronik på en distans från handen,inklusive motorn själv, var tanken att skapa ett systemsom är kompatibelt med de konstruktioner som Enablingthe Future använder.För att förverkliga detta konstruerades en prototyp somtestats. Prototypen använde sig av en muskelsensor somlät användaren kontrollera proteshanden genom att spännasin arm. Distansen mellan de elektriska komponenternaoch protesen var ungefär en och en halv meter, samtidigtsom tillräckligt stor kraft kunde transporteras för att stängahanden med ett tillräckligt grepp.

Wireless Control of a Robotic Arm / Trådlös styrning av en robotarmIssa, Alan, Andreanidis, Christos January 2021 (has links)
This paper looks at all aspects of developing a robotic arm and hand that consists of five fingers which is able to imitate human movements. The imitation ability, accuracy and factors affecting both points are studied. A project like this requires the interplay of various electrical components to achieve the desired results.The prototype constructed measured the controller’s movements of the fingers with the help of flex sensors. The movements in the elbow and wrist however were measured with the help of potentiometers. The flex sensors and potentiometers were connected to an Arduino Mega which then sent the values with the help of a transmitter. The robotic arm consists of an Arduino Uno, seven servomotors and a receiver that reads the messages sent from the transmitter. All values were converted into degrees that rotated the motor axles accordingly. The prototype produced positive results, showing that it was able to copy all movements done by the controller. Tests were conducted to study the accuracy and imitationability. The conclusion was that the factors affecting imitation and accuracy were mostly connected to the weight of the robot and the design of the hand. / Denna uppsats behandlar olika aspekter i utvecklingen av en robotarm vars gripdon är en hand med fem fingrar, med syfte att kunna imitera mänskliga rörelser. Imitationsförmågan, noggrannheten samt vilka faktorer som påverkar dessa studeras. För att uppnå ett önskvärt resultat har det krävts styrning och samverkan mellan olika elektroniska komponenter. I prototypen som presenteras mättes fingrarnas rörelsemed hjälp av flexsensorer samt rörelsen i armbåge och handleden med hjälp av vridpotentiometrar. Flexsensorerna och potentiometrarna var anslutna till en Arduino Mega vars värden skickades med hjälp av en sändare. Elektronikkomponenterna som användes i robotarmen var en ArduinoUno, sju servomotorer och en mottagare, vars funktion var att läsa av meddelanden som skickades från sändaren. Alla värden omvandlades till grader och motoraxlarna roterade i enlighet med dessa. Prototypen uppnådde ett önskvärt betteende då roboten hade förmågan att imitera alla rörelser som utfördes av styrenheten. Noggrannheten och imitationsförmågan undersöktes med olika tester. De mest betydelsefulla faktorer som påverkade imitationen och noggrannheten av prototypen var kopplade till vikten av roboten och designen av handen, enligt slutsatserna som har dragits.

Design and Stability of a Quadruped Robot / Design av en balanserande fyrbent robotLindestam, Algot, Lorang, David January 2021 (has links)
We are currently in a revolution in robotics where more tasks are being handled by machines than ever before. For this reason, the goal of this project was to build a four-legged robot with an implementation of dynamic stability. The developed robot is a dog style robot with reversed knee joints. The robot is controlled by an Arduino UNO microcontroller, that processes information from a gyroscope to drive it’s servo motors. It is capable of maintaining it’s balance while standing on a varying incline. The motion is based upon an inverse kinematic model of the leg geometry and assumes a planar ground surface. / I dagsläget ser vi en snabb expansion i användningen av robotar för att utföra alltmer avancerade uppgifter. På grund av detta var målet med detta projekt att utveckla en fyrbent robot med en enkel implementation av självbalansering. Den framtagna prototypen är en robot av hundstil med bakåtgående knän. Styrenheten är en Arduino UNO mikrokontroller. Med information från ett gyroskop styr denna roboten med hjälp av dess servomorer. Prototypen är kapabel att hålla balansen då den står på lutande underlag. Rörelsen är baserad på en kinematisk modell av bengeometrin och förutsätter en plan markyta.

Brailled : A Braille translation aid / PunktskriftsöversättareDandanell, Josefin, Henriksson, Agnes January 2021 (has links)
The purpose of the project was to develop a product that would serve as a support for the learning of Braille. Learning Braille is a time consuming process. People who have recently suffered a visual impairment have a lower sensitivity to touch than those who have been visually impaired for a longer period. According to a study [1], the learning process can lead to depression. At the same time, the technology for support systems for the visually impaired is underdeveloped. The questions examined in the project were partly about the environment’s influence on the accuracy of the instrument’s translation of Braille. Partly, if it was possible to create an instrument that can translate Braille in standard format and at the same time be a suitable aid for a user with a visual impairment. The instrument consisted of four main parts; reading surface, reading head, audio output and keyboard. The purpose of the reading surface was to place the Braille to be translated under the reading head using a stepper motor. The reading head would then interpret the letter, which would then be called out as an audio file using the audio output. All operations of the instrument would be controlled by a keyboard with three push buttons. The resulting product was promising. The analysis showed that it was fully possible to create a functioning Braille translator. However the product requires some further development in order to be used as an effective aid / Syftet med projektet var att ta fram en produkt som skulle fungera som ett stöd för inlärning av punktskrift. Personer som nyligen drabbats av en synskada har sämre känslighet för beröring än de som varit synskadade under en längre period. Enligt en studie [1] kan tidskrävande inlärningsprocessen leda till depression, samtidigt som tekniken för stödsystem åt synskadade är underutvecklad. De frågeställningar som undersöktes i projektet handlade dels om omgivningens påverkan av exaktheten av instrumentets översättning. Dels om det var möjligt att skapa ett instrument som kan översätta punktskrift i standardformat och samtidigt vara ett passande hjälpmedel för en användare med en synskada. Instrumentet bestod av fyra huvudsakliga delar; avläsningsyta, avläsningshuvud, ljudutgång samt tangentbord. Avläsningsytans syfte var att placera punktskriften som skulle översättas under anläsningshuvudet med hjälp av en stegmotor. Avläsningshuvudet skulle därefter tolka bokstaven som sedan skulle utropas som en ljudfil med hjälp av ljudutgången. Instrumentets samtliga operationer skulle styras av ett tangentbord med tre tryckknappar. Resultatet av den framtagna produkten var lovande. Undersökningarna påvisade att det var fullt möjligt att skapa en fungerande översättare. Dock krävs det en vidareutveckling för att produkten skall kunna användas som etteffektivt hjälpmedel.

Modelling of electromechanical motors for turret and barrel control in main battle tanks / Modellering av elektriska motorer för drift av torn- och eldrörstyrning i stridsvagnarCarlstedt, Arvid January 2021 (has links)
In this master thesis the dynamics of a modern main battle tank's turret traverse and gun elevation have been modelled. The models of dynamic motion have been coupled to two different types of electric motors, namely a direct-current motor and an induction motor. These have been modelled in MATLAB and SIMULINK together with the mechanical systems in the turret traverse and gun elevation. The goal of this project was to develop non-ideal models of the combined mechanical and electrical systems, but the main focus has been the dynamics of the electric motors. / I denna examensavhandling har modeller av elektriska motorer som driver tornet samt elevation av eldröret på en stridsvagn tagits fram. De två motorer som undersökts är en likströmsmotor och en induktionsmotor. Dessa har kopplats till mekaniska system som representerar rotation av stridsvagnens torn och elevation av eldröret. Modelleringen har gjorts i MATLAB och SIMULINK. Målet med denna studie var att ta fram icke-ideala modeller av både de elektriska motorerna och de mekaniska systemen för torn- och eldrörsdrift.
