In the Lego Technic world, universal joints are generally used. They are used in tranmission lines, in all kind of situations where the possibilities of gears stop etc… . But they have a disadvantage. The angle between the horizontal should not be more than 45 degrees. Then you “split” them. The ádvantage of them is that they are not big. I have made u-joints that can stand larger angles. The smaller angle one is for the situation when you don’t have the unique lego u-joints.

A disadvantage of my u-joints is that they are large. But if you have space for them, for example in tractors or in lego factories they are handy.
This photo shows us the large u-joint. It’s large angle you can see in the video
An advantage of this u-joint is that it's angel is big and the motor force, which could be transported, is big.
This is the small u-joint. When you have room, no (more) u-joints and this material, this would be a solution. However, the unique lego u-joint is better.
