After we had finished our final design this week, we bought wheels and motors for our robot. Finally we bought two 50 mm aluminum wheels with a bore of six millimeter. We also bought two 12 V, 380RPM engines which will presumably arrive on the sixth of January 2019.

We paid attention to the size of the 3D Model. The total size of the robot will be 200 x 170x 73 in millimeters. The supporting surface will be created by using a 3D printer.
