With this design, I wanted to create a caster drive that wasn’t massive, or enormous, or impossible to manufacture, so that maybe something similar could eventually be used on a competition robot.
I have also wanted to try using Onshape for a while now, so I took the opportunity to kill two birds with one stone. My experience with Onshape was a positive one in general, but it had some blemishes. I might go into more detail in a later post.
Here is a link to the CAD model. Because it’s in Onshape, you should be able to view it without downloading any software.
