This thesis describes the design and evaluation of two devices to be included in the next generation of the family of devices called the Boundary Layer Data System (BLDS). The first device, called the Quasi-Static Strain Data Acquisition System, is a continuation of the BLDS-M series of devices to be known as the Flight Test Data System (FTDS) that uses a modular approach to acquire non-flow, quasi-static mechanical strain measurements. Various breakout boards and development boards were used to synthesize the device, which were housed by a custom PCB board. The system is controlled by the SimbleeTM System on a Chip (SOC), and strain measurements are acquired using the HX711 analog-to-digital converter (ADC), and acceleration measurements are acquired with the ADXL345 accelerometer. The Arduino IDE was used to program and troubleshoot the device. The second device, called the Dynamic Strain Data Acquisition System, is a laboratory proof-of-concept device that evaluates various methods of acquiring dynamic strain measurements that may be used in future FTDS designs. A custom PCB board was designed that houses the microcontroller and the various passive components and ICs used to acquire and store strain measurements. The system is controlled by the Atxmega128A4U microcontroller, and measurements are acquired using the AD7708 external ADC and the on-board ADC of the microcontroller. Atmel StudioTM was used to program the microcontroller in C/C++ and to troubleshoot the device. Both devices were tested extensively under room temperature and low temperature conditions to prove the reliability and survivability of each device. The quasi-static data acquisition system was validated to acquire and store measurements to a microSD card at 10 Hz, with a peak operating current under 60 mA. The dynamic data acquisition system was proven to acquire a thousand measurements at 1 kHz and store the data to a microSD card, with a peak operating current under 60 mA.

We use autonomous line-following robots in various industrial environments, surveillance applications, and construction and mining industries for object transportation tasks where rail, conveyer, and gantry solutions are unavailable. They help us reduce the work process and improve efficiency. In this report, we will illustrate how a 2WD robot can move on a predefined path and detect obstacles along the way. In this project, we have used a proximity sensor to detect the obstacle in the path and turn the robot from the obstacle. Also, we used an IR sensor so that robot could follow along the predefined path. The used in the project sensors were connected to Arduino UNO, which was programmed to control the robot's movements and decisions. By employing these two techniques, we can efficiently use such robots in various scenarios. For example, in the current Covid scenario, physical contact has become minimal, so if we use this line-following robot to deliver medicines to the patient, the physical contact between people can be reduced. The obstacle avoidance robot technique can be used in cars to improve safety. If an obstacle is detected in the path of the car and the driver does not apply the brakes, this type of technique can be used to bring the car to a stop by applying breaks. Using the proposed robotic techniques we can save time and work efficiently with minimal physical touch. Overall, the project achieved its primary goal of moving the robot on a predefined path and detecting obstacles on the path

Sjöfartshögskolan i Kalmar har ett långtgående studentprojekt att bygga en modell av skolfartyget M/S Calmare Nyckel som autonomt ska köra runt i en damm på skolan för att visa upp skolans profil. Projektet är tänkt att sammanfoga kunskaper från många olika delar av utbildningen såsom elektronik, programmering, och stabilitet. Detta arbete syftar till att undersöka Ultra Wideband som teknik för positionering av modellen för att i framtiden kunna använda positionen för att navigera i dammen. Specifikt så användes tre chip av typen ESP32 UWB som implementation av Ultra Wideband då det var ett billigt alternativ som verkade lovande. Två av chippen var stillastående på kända positioner och positionen för det tredje chippet räknas ut med hjälp av triangulering. Den uppmätta noggrannheten för systemet anses inte vara tillräckligt bra för att fortsätta med ESP32 UWB i fortsättningen av projektet.En båtmodell av M/S Calmare Nyckel togs fram med hjälp av CAD programmet Autodesk Fusion 360 och tanken är att båtmodellen ska 3D printas på universitetet och sedan byggas ut med RC komponenter så båtmodellen kan göra fart genom vatten. Tanken är även att båtmodellen ska kunna manövrera helt autonomt till en laddstation för att sedan återvända ut på sin planerade rutt. Med hjälp av forum och experter online så har alternativ till vilka typer av komponenter såsom, elmotor, styrservo, propeller och annat som behövs för driften tagits fram. Alternativen är bara förslag på vilka komponenter som rekommenderas och inga exakta modeller. / The Kalmar Maritime Academy have an ongoing student project to build a model of the academy’s training ship M/S Calmare Nyckel. The model is supposed to autonomously sail around a pond located in the academy’s premises to show off the academy’s profile. The project is intended to combine knowledge from many different parts of the program such as electronics, programming, and stability. This project aims to investigate Ultra Wideband as a technology for positioning the model to be able to use the position to navigate the pond. Three ESP32 UWB chips were used as an implementation of Ultra Wideband as it was a cheap alternative that showed promise. Two of the chips were stationary at known positions and the position of the third chip is then calculated using triangulation. The measured accuracy of the system is not considered good enough to continue with the ESP32 UWB in the continuation of the project.A boat model of M/S Calmare Nyckel was produced using the CAD program Autodesk Fusion 360 and the idea is that the boat model can be 3D printed at the university and then expanded with RC components so that the boat model can make speed through water. The idea is also that the boat model should be able to maneuver completely autonomously to a charging station and then return to its planned route. With the help of online forums and experts, alternatives to the types of components such as electric motor, steering servo, propeller, and other things needed for operation have been developed. The options are only suggestions of which components are recommended and not exact models.

Researchers often work on experimental setups that are highly specialized and usually designed and manufactured for a single or a few test series. The challenges for automation technology and measurement data acquisition in the apparatus are as unique as these experimental setups. In the following, Bochum University of Applied Sciences presents its approach to implementing different measurement and automation tasks in a flexible but also standardized way. Existing microcontrollers such as Raspberry Pi, Arduino or Controllino are used as the basis for the greatest possible flexibility. It is often not necessary to record high-precision measurement data. In this cases inexpensive development boards can be used that already include peripherals for direct connection to Arduinos or Raspberry Pi’s. Such development boards are often offered at very low cost and with short delivery times for many different measurement tasks. In this paper, the implementation of the requirements is discussed using a current project that deals with thermal energy recovery using 'smart materials' (shape memory alloys) as an example.

This thesis contributed to the regional Health School project, specifically informing the community- building efforts of a preschool in Örkelljunga, Sweden as they seek ways to improve communication among immigrant families and teachers. Using a co-design process with stakeholders including a preschool teacher, architects redesigning the school, and a health sciences researcher, this research investigated how a welcoming atmosphere could be created to act as a social intervention in the redesigned school. Interactive ambient light installations are proposed as a way to create this welcoming atmosphere. Installation design was explored through the lenses of multicultural makeup; play behaviour; accessibility and lighting design. Concluding the design research process, which used methods of participatory design, experience prototyping (Buchenau and Fulton Suri, 2000), and live prototyping (Horst and Matthews, 2016), a set of design principles were distilled for stakeholders.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context.I have explored different light sources and compared them to each other and given a shortdescription of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms.I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations. The wall is built using modules to enable it to be scaled up and down to fit different contexts.

Det här examensarbetet bygger vidare på en tidigare konstruerad prototyp, ett interaktivt konstprojekt där två plattor, placerade på en båge, med vattenmunstycken i mitten styrs med en joystick. Plattorna följer joystickens rörelse med hjälp av servomotorer.Målet i detta examensarbete var att koppla åskådarens smarta mobiltelefon till konstprojektet. Åskådaren ska kunna styra konstprojektet genom att vinkla sin mobiltelefon. Även vattenflödet ska kunna kontrolleras och all interaktion ska ske via trådlös kommunikation.Målet har uppnåtts genom att användaren installerar en applikation som skapats för operativsystemet Android. Applikationen skickar information om mobiltelefonens aktuella vinkelposition till en server via ett trådlöst nätverk. Servern skickar i sin tur vidare denna information till en Wifi-modul kopplad på ett arduinokort som ställer in plattornas servomotorer i rätt läge. Rapporten beskriver hur tekniken för att nå målet fungerar och illustrerar även hur prototypens design och funktionalitet har förändrats för att få ett mer effektfullt intryck. / In this thesis we further develop an existing prototype. The prototype is an interactive art project where two plates with water nozzles in the middle are placed at each end of an arc. These two plates can be controlled directly with a joystick. The plates are following the motion of the joystick using servo motors. Our main goal is to allow spectators of the art project to remotely control the plates and the water flow by using their own mobile phone.Our goal has been achieved by creating an Android application that the user can download and install directly on their mobile phone. The application automatically sends information about the angular position of the phone to a server. Then the server forwards this information to a Wifi-module connected to an Arduino board which is moving the servo motors, attached to the plates, in the correct position.This thesis describes the technique used within the project and also illustrates how the design and functionality of the prototype has been changed to make a more striking impression on the audience.
