Hello Question about model.

Hello every one. I just saw these image in an video of solid works (the video competitive robots number one which shows that image). I don´t know if someone or perhaps the group administrator knows if I can find these tutorial on Solidworks Webpage. Since I am interested in the area and will be very helpfull to look a tutorial with a model like that (or that one).

Thanks in advance perhaps the question it is unusual, but any information will help.
