Why no solutions are provided for the exercises?

I wonder why no solutions are provided for the exercises in this course. It seems that most exercises and examples depend on the solutions of previous exercises. That means, if I get stuck on one exercise, I can no longer proceed.


The reason is that the course is done that why so that you learn the basics first and build on top. It makes no sense to try to use XACROS if you didn’t understand URDF first.

But any way, here are some solutions: Bitbucket, hope they help
