So I have only just started working with analyzing center of gravity (CoG) and there is something I can not figure out.
I opened up Mass Properties - I clicked preview - and the CoG was in between the robot's two back wheels. I added two large blocks of iron to the front of the robot and the CoG did not change.
(Here are some images to help explain my problem.)
The CoG is located between the black wheels in the back.
The CoG is still located between the two black wheels. Even with two 12x12 blocks that are assigned the material FE 20.
I have a feeling this is a beginner's mistake.
