I have been upgrading information on my site. I have added in more onformation on a range of topics. There are two sections to the site which I am going to merge eventually

http:// bettscomputers.com/roboticsystems.htm

most of the stuff is here http://bettscomputers.com/moodle/course/vie w.php?id=5&topic=all

Unfortunately the navigation lacks and you really need to examine all the links. Gradually I am fixing it. I would appreciate any feedback you can. Also if anybody wants to write any articles to add in it would be good. I intend to put more links to videos and articles which people have written in Robots.net Anyway feedback would be great. perhaps you feel there is a topic which really needs to be covered. let me know. graham_betts@yahoo.com
