Take a look at this website- wonder how to . com
http://www.wonderhowto.com/search/nxt-lego-line-follow/
It has a bunch of Lego NXT programs and does good job of explaining them. Not
sure it's exactly what you're looking for, but might lead to it :)

Subject: RE: [VADCFLL-L] measured turns
Thanx Brandy. The timing of this could not have been better. My team is still
continuing to meet on the incomplete missions and also come up with a better
robot design and also do missions with a better programming style. Some of this
is also based on Lessons learned.
Yesterday during our class, some of them were having difficulties writing a line
follow program.
So if any of you can share with us the links on either basic programming or a
better programming style or a good robot design etc., that will really help.
I don't want the kids to copy or download programs from net only to have their
missions work.
Thanks for all the help.

I made this sheet today because I work with kids from varying degrees of
mathematical backgrounds. They were not getting the lesson plan devised by
either the Educate NXT curriculum or the C.M. robotics engineering vol 1. So I
created a sheet that I hope plainly list the step involved in figuring out how
to make calculated, measured turns.
It does not include a lesson plan for the worksheet, but that is pretty easy-
Get your kids to create an attachment for the edu-bot that will hold a marker
in place over the middle of a wheel.
Get them to create a program that will allow the robot to spin/pivot in a full
circle. (Marker is over the outside wheel spinning. Only one motor should be
running so the robot circles around it's one inside wheel.)
Once you do that, you will have all the parts you need to run a course and make
measured turns using the worksheet I created.
A version of this lesson is in the Educate NXT, but in the author's obvious
superior math skills, he failed to include the equation on HOW to find the
distance traveled by the wheel, which you need to know in order to convert into
rotations. The Carnegie Mellon included it, and did a good job of stopping the
videos so I could talk about what was happening, but many kids didn't understand
WHY it was happening. The worksheet they created didn't have steps, which my
student forgot instantaneous to shutting off the video that explained it, so I
spent this morning trying to make one up myself. Hope it helps someone else as
well!
If the attachment doens't come through, please email me and I will send it to
you.
Regards,
Brandy
