Street sweepers have been riding the streets for years, sweeping up everything they encounter. The side sweepers of these street sweepers have shown in practice that they actually do what they are made for. By applying these side sweepers in our concept, we not only ensure that the plastic waste is directed to the center of the robot. These sweepers also ensure that the litter range of the robot is larger as they reach out past the width of the wheelbase. Street sweepers use sweepers with hairs on them. This will not work well on the beach because these hairs will cause the sand to be directed to the center of the robot as well which requires extra power from the motors. As, </ins>in <ins style="font-weight: bold; text-decoration: none;">our concept, we want to sweep up loose pieces of plastics instead of dirt, these hairs have been replaced </ins>by <ins style="font-weight: bold; text-decoration: none;">hooks. By making different prototypes </ins>of the sweepers <ins style="font-weight: bold; text-decoration: none;">(with hooks at angles of 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees and 130 degrees), it has become clear after various tests that hooks in angles of 120 degrees work best. These 120 degrees provide optimal reach and grip strength </ins>on the <ins style="font-weight: bold; text-decoration: none;">plastic waste. By not making these angles too sharp, it is ensured that the plastic waste does not get caught in the hooks. As can be read under the heading "RPCs", there is a requirement that the robot must be able to clean up plastic waste of 50 grams. However, the motors should be able to handle the rotation of the sweepers and should be able to pull plastics out from under the sand. These sweepers are quite large and will be made of a sturdy but light material. When exploring materials that have such features, aluminum was ranked highest. Aluminum is a very compatible material for this as it is very robust </ins>and <ins style="font-weight: bold; text-decoration: none;">lightweight. This is perfect for </ins>this <ins style="font-weight: bold; text-decoration: none;">use as the sweepers should be as light </ins>as <ins style="font-weight: bold; text-decoration: none;">possible but still sturdy. In the final product, these sweepers will also be quite large. Which again means that the DC motors must still be strong. All in all, despite the minor change from hairs to hooks, the concept of using sweepers to direct litter to the middle of the robot still proves to be </ins>effective <ins style="font-weight: bold; text-decoration: none;">and capable of the goal it has within our design both on the the street sweepers and in our prototype</ins>.</div></td></tr>

The conveyor belt was now turned solely by friction of the belt on his axis. In further iterations, this will be replaced by a mechanism that is quite similar to a bike’s. The use of a metal chain between both axis will ensure the belt is being rotated on 2 ponts. The axis will be made out of metal and will be mounted with bearings to the base to minimize friction</ins>.
