Tyler Whitney has written an article on programming LEGO Mindstorm using the My namespace robots for Coding 4 Fun. What is the My namespace? It is a new feature in Visual Basic 2005 that helps put commonly used functionality at your fingertips. Tyler has provided a very nice, quick overview all about the My namespace in the world of LEGO API.
The project does require you to have a LEGO Mindstorm RCX 2.0 unit.
