CAD lift tutorial

For this year’s game, our team has decided to make a CAD before actually building the robot (we built and then took apart 3 robots in a span of 4 months). Everything seems to look fine, but I’d like to be able to show my team how the arm would work. But every time I try, something either breaks when I move one of the pieces or stops moving all together. Does anybody know of any good tutorials on how to make a fully functioning lift on Autodesk Inventor?
