    Several people during RoboGames 2009 asked me to create a printed version of the RioBotz Tutorial. So I generated a press-quality version of the text (better quality than the one from the downloadable PDF) and uploaded it to http://www.lulu.com, which is a very well-known publishing company/website. I've just bought a few printed copies and the print quality is excellent.

    The tutorial ended up very cheap, because I'm not getting any money out of it, the price only covers the printing costs. It can be safely bought directly from lulu.com, which will print it in 3 to 5 business days and ship to any USA or international address.

    The 374-page black and white version ended up only US$10.23 plus shipping, it can be bought at
    http://www.lulu.com/content/7150541
    It's 8.5 x 11, with perfect binding and publisher's grade paper, and color cover.

    I've also generated a full-color version on very high quality paper, however the printing costs make it US$80.30 plus shipping. The link is:

    It's much more expensive but it is worth it, considering that there are 895 figures in the tutorial, most of them in color.

    I hope you enjoy this humble contribution to this great sport!
