Detta examensarbete handlar om att ta fram ett koncept på alternativa borstar och en bottenplåt i alternativt material för Weda W50. Anledningen till detta är att dagens borstar kräver ständig och noggrann rengöring för att inte haverera samt att bottenplåten orsakar elektrolytisk korrosion på resterande komponenter. För att kunna uppnå godtagbara resultat har metoder som idégenerering, materialsökning, modellering samt prototypframtagning använts. I genomförandefasen har tester utförts för att få en demonstration på hur de slutgiltiga komponenterna kommer att fungera i praktiken. Efter en avslutad genomförandefas blev resultatet fasta borstar med omdesignade länkarmar samt en bottenplåt i ABS-plast, vilket presenterats med både 3D-modellering och i fysisk komponent. Därmed har målen och syftet med detta examensarbete uppfyllts. / The purpose of this thesis is to examine and generate alternative concepts for the pool brushes and bottom plates used in the W50 underwater cleaning robot. The reason is that the current rotating brushes used on the W50 require thorough and consistent servicing to function as advertised, the other cause is that the bottom plate is produced in stainless steel which causes electrolytic corrosion on the surfaces of other components that are made in aluminum. Brainstorming, material research, 3D-modeling and prototyping were used to achieve tangible results. Several tests were conducted during the execution phase to give a live demonstration of how the final product is meant to perform. The results of the execution phase became fixed brushes for the W50, redesigned control arms and a bottom plate in ABS plastic. The results of this thesis work were demonstrated with the help of both 3D-modeling and physical models. Finally, the goals and purposes of this thesis were achieved.

The outcome of my thesis is airy relief in the form of a spreaded Kyjov´s women's folk costumes. It is made up of embroidery and lace, which gets their original lightness without underlying substance.The white color, I have used, strenghts this feeling. All parts are printed by the ABS plastic. I follow the transformation of hand-made embroidery on the machine-made one with this. 3D printing is another entirely fictitious step for me. Just as the embroidery machine adjusts stitches according to their outline, as well as 3D printer has its own structure of applying material.
