Stopping Glyph Damage

Task: Stop Destroying Glyphs

Since damaging field elements is a huge no-no, we needed to fix this, we decided to create a 3-D part to protect the glyphs from our wheels

Model:

During the first attempt, I had just self taught Creo hours prior to construction. As a result, I was not very precise nor efficient in my design. Nevertheless, we recognized that there were some basic shapes we could use for construction such as a semicircle for the bottom half and two rectangles on the top part. We decided to use measurements that were estimated from a singular mechanum wheel. This culminated in the design below.

Result:

The part itself is made out of nylon as usual. Our main issue was measuring the wheel accurately to create a functional part. The two parts hampering the design was that the U-shape must be off the ground slightly, and that the shape's semi-circle would not have the full radius of the wheel. So, we iterated through various designs of the U-shape, changing the height off the ground by ~1mm each time. We also varied the radius, until we realized that we could measure the width of where the semi-circle segued into the rectangle and get the estimated diameter of the semi-circle.
