Abstract [en]

Although a robot vacuum cleaner is a well-known product, development is still interesting. Better working sensors and more sophisticated algorithms and sensors are used in new cleaners.

The purpose with this thesis was to learn more about different sensors, algorithms, and designs of robot vacuum cleaners, to try ideas and to find improvements to implement on the demonstrator.

The initial work was to make a market investigation to find customer needs and expectations. Also making a rough design and layout for the mechanical and electrical system.

The budget for the demonstrator was 1000 SEK. Using laser cut plastic sheets, 3D printed parts, and receiving motors for free, costs did not exceed budget. Literature and theses in the area of interest were studied to find answers to some of the research questions. The theses studied subjects such as driving pattern and designs to find back to charge station. Some ideas for driving patterns were implemented on a demonstrator. The development method used was iteration of finding useful information, testing components, codes and also the complete demonstrator.

The components used were DC motor, stepper motors, ultrasonic sensors, Arduino mega micro controller, switches and AA batteries. The different components required different voltage and the stepper motors used driver cards.

Abstract [sv]

Även om robot dammsugare är en välkänd produkt är produktutveckling fortfarande intressant. Bättre sensorer och mer sofistikerade algoritmer och sensorer används i dammsugare.

Syftet med denna avhandling var att lära sig mer om olika dammsugare, algoritmer och konstruktioner av robot dammsugare, för att prova idéer och möjliga hitta förbättringar att implementera på demonstranten.

Det första arbetet var att göra en marknadsundersökning för att hitta kundens behov och förväntningar. Även att göra en grov design och layout för det mekaniska och elektriska systemet. Budgeteringen för demonstranten var 1000 kr. Kostnaderna översteg inte budgeten eftersom vi använde oss av laser skurna plastplattor, 3D-printade delar och erhöll motorer utan kostnad.

Sex olika avhandlingar studerades för att hitta svar på några av frågorna. Avhandlingarna studerade ämnen som körmönster och mönster för att hitta tillbaka till laddstationen. Vissa idéer för körmönster implementerades på demonstranten. Den använda utvecklingsmetoden var iteration av att hitta användbar information, testa komponenter, koder och även den fullständiga demonstranten.

De komponenter som användes var likströmsmotor, stegmotorer, ultraljudssensorer, Arduino mega-mikrokontroller, strömbrytare och AA-batterier. De olika komponenterna krävde olika spänningar och stegmotorn använder ett specifikt drivkort.
