This is a self-directed class.
What you learn in the tutotial is the best help you will get in building, programming and uinderstanding the Lego Mindstorms Robot.
I recommend that you gp through all tutorials before laying hands on the robot.
I have a work along worksheet to go with the tutorial.
Here is the link to the tutorial: http://www.ortop.org/NXT_Tutorial/index.html
Please ask for the worksheet.
