Technology in agriculture has in recent years gone from being traditional equipment for agriculture to digital monitoring systems, data collection, and optimization of various processes. The technology within the agriculture domain is called AgTech. Agricam is an AgTech company that have developed a product called Bacticam that combines software, hardware, and veterinary expertise to solve problems in milk production for farmers. Bacticam is a station for bacterial cultivation that is located on the farm and operated by the farmer. Bacticam enables farmers to grow bacteria and analyze milk samples on the farm, with the help of artificial intelligence (AI), to determine the condition of the milk and the overall health conditions of the cow. Bacticam analyses bacterial colonies by taking two photographs of the bacterial growth on the milk samples. These two photographs are taken within certain time intervals with two different light settings to highlight certain parts of the bacterial growth sample images for analysis. The process of photographing the samples is done by using a fixed Android mobile phone. Today, the Bacticam requires the user to switch the light settings manually which poses a risk of contamination to every analyzed sample. A solution to this problem would be to automate the change of light setting during the photography process by connecting custom control electronics, through Bluetooth, to the Android device. The problem explored in this thesis is the lack of designs of systems that control lighting remotely from Android devices and custom control electronics through a Bluetooth interface with a focus on customer experience (CE) and developer experience (DE). The goal is to contribute to new solutions in the AgTech domain with a focus on CE and DE. The result to the stated problem is called the Automatic Bacterial Lighting System (ABLS), which automates the process of changing the light setting during the photography process of bacterial colonies in milk samples for the Bacticam. The ABLS increase the reliability of the Bacticam by reducing the number of interactions the customer has to perform. The ABLS have been developed to establish a stable Bluetooth connection between an Android device and custom control electronics with a focus on both CE and DE. A literature study was conducted prior to the development of the ABLS to explore the domain and gain a better understanding of the issue at hand. / Teknik inom jordbruk har under de senaste åren gått från att enbart bestå av klassisk utrustning för jordbruk till digitala övervakningssystem, datainsamlingar samt IT optimeringar av diverse processer. Dessa moderna tekniklösningar inom jordbruksdomänen kallas för AgTech. Agricam är ett AgTech företag som har utvecklat en produkt som heter Bacticam, som kombinerar mjukvara, hårdvara samt veterinärkompetens för att lösa problem inom mjölkproduktion för mjölkbönder. Bacticam är en station för bakterieodling och sköts och hanteras på gården av mjölkbonden. Bacticam gör det möjligt för mjölkbönder att odla bakterier och analysera mjölkprover på sin gård med hjälp av en AI, för att på så sätt fastställa kvaliteten på mjölken samt kons hälsotillstånd. Bacticam analyserar bakteriekolonier genom att ta två bilder på bakterietillväxten på mjölkproverna. Dessa bilder tas inom vissa tidsintervall med två olika ljussättningar för att skapa en ordentlig profil av bakterieodlingen. Processen med att ta de två fotografierna görs med hjälp av en fastmonterad Androidmobiltelefon. I nuläget kräver Bacticam att användaren byter ljusinställningen manuellt under fotograferingen. Detta innebär en risk för kontaminering vid varje analyserat prov som tas. En lösning på detta problem är att automatisera bytet av ljussättningen under fotograferingsprocessen genom att ansluta styrelektronik till Androidmobiltelefonen via Bluetooth. Problemet som denna avhandling hanterar är bristen på kunskap om utformning av system som fjärrstyr belysning från Androidenheter via ett Bluetoothgränssnitt med hjälp av anpassad styrelektronik med ett fokus på kund- och utvecklarupplevelse. Målet var att bidra till nya lösningar inom AgTech-domänen med fokus på kund- och utvecklarupplevelse. Resultatet till det angivna problemet är döpt till Automatic Bacterial Ligting System (ABLS) och automatiserar ljussättningen under fotograferingsprocessen för att på så vis öka tillförlitligheten på Bacticam genom att minska antalet interaktioner som krävs av användare för att hantera Bacticam. ABLS har utvecklats för att skapa en stabil Bluetoothanslutning mellan en Androidenhet och anpassad styrelektronik med fokus på både kund- och utvecklarupplevelse. En litteraturstudie gjordes inför utvecklandet av ABLS för att bekräfta att avhandlingsproblemet var unikt samt att ABLS därför skulle lösa ett unikt problem. En utvärderingsmodell upprättades för att underlätta analysen samt bekräfta validiteten av ABLS.

No. of bitstreams: 1 Alessandro Mancio de Camargo.pdf: 8611897 bytes, checksum: 9929ffa3d48991fd82321127b7944e6b (MD5) Previous issue date: 2018-11-26 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Agricultural activity takes advantage of several new technologies, whose structural and technical advances have been expressed since the last century, for example, through chemical fertilizers, transgenic crops, digital code, multimedia, interactive mobility. This thesis outlines in detail this process through historical records such as those of the great acceleration (STEFFEN et al., 2015), a series of innovations that since 1950 have been driving the growing role of cognitive and technological power in the design of the future and that already leaves an effective geological mark on the planet, identified as Anthropocene. Therefore, this thesis revisits the rural origin of the great acceleration and discusses how it repeatedly presents itself in disruptive technologies in digital agrosystem as described, among others, by Massruhá et al. (2014) and Bernardi et al. (2014) of Embrapa Informática and Embrapa Instrumentação, respectively. This work adopts the technography proposed by Jansen and Vellema (2011), which is a method that balances the technical, biophysical, cultural, economic and cognitive dimensions seen in agriculture, as a methodological strategy to solve the following problem: In what way do several elements and dynamics (climate, soil, machines, farmers, digital code) have their relations and exchanges affected by ubiquitous connectivity? As a conclusion, this thesis shows that the digital agrosystem increasingly encourages and rewards relational logics aimed at the potential of profiting from rural knowledge rather than the ability to produce food. Thus, both abductive-inductive and deductive agrosystems – such as the fuzzy Javanese domestic garden and Gotham Greens technological urban agriculture, for example – must be equitably linked to complete, deep and interactive networks to meet and understand ecosystem needs in order to enhance cooperation between the different modes of relations and cognitive exchanges existing in the field. This requires the universalization of the essential skills that allow integration into digital agrosystem in a reliable and transparent way / A atividade agrícola tira proveito da emergência de diversas novas tecnologias, cujos avanços estruturais e técnicos expressam-se desde o século passado por meio, por exemplo, dos fertilizantes químicos, dos transgênicos, do código digital, da multimídia, da mobilidade interativa. Particularidades desse processo são discutidas neste trabalho por meio de registros históricos como os da grande aceleração (STEFFEN et al., 2015), uma série de inovações que a partir de 1950 orienta o crescente papel do poder cognitivo e tecnológico em conformar o futuro e já deixa uma marca geológica efetiva no planeta, identificada como Antropoceno. Assim, esta tese recupera a origem rural da grande aceleração e discute como ela se multiplica em tecnologias disruptivas no agrossistema digital como descrito, entre outros, por Massruhá et al. (2014) e Bernardi et al. (2014) que atuam na Embrapa Informática e Embrapa Instrumentação, respectivamente. Para tanto, adota-se como estratégia metodológica a postura tecnográfica de Jansen e Vellema (2011), que leva em conta a integração na agricultura das dimensões técnicas, biofísicas, culturais, econômicas, cognitivas para solução do seguinte problema levantado: De que maneira diversos elementos e dinâmicas (clima, solo, máquinas, agricultores, código digital) têm suas relações e trocas afetadas pela conectividade ubíqua? Entre as respostas apresentadas, a conclusão do trabalho indica que o agrossistema digital incentiva e premia lógicas relacionais cada vez mais voltadas ao potencial de explorar o conhecimento rural do que, propriamente, à habilidade de produzir alimentos. Logo, agrossistemas tanto abdutivos-indutivos quanto dedutivos – tais como o intrincado jardim doméstico javanês e a tecnológica agricultura urbana Gotham Greens, por exemplo – devem vincular-se equitativamente a redes plenas, profundas e sinergéticas de entendimento e atendimento do ecossistema, a fim de ampliar a cooperação entre os diversos modos de relações e trocas cognitivas existentes no campo. Isso requer a universalização das habilidades necessárias para integrar-se ao agrossistema digital de modo confiável e transparente
