LEGO EV3 Tutorial 8 UPDATE: Data and Loop Line Follow Program

This is an update to a previous video I created a few weeks back. I have been pushing out a wide variety of line following programs. The video  I shared previously covered how to use data blocks, data wires, and a loop block to line follow. One of the great questions that came from the video was how to move the robot back to being straight when it kicks out of the loop interrupt. At the end of the run there is a perpendicular black line that kicks the robot out of the line follow program. However, originally the robot would swivel at the end which would not be ideal if you are doing FLL or other programs outside of the line follow program.

This update includes one way to solve this problem. Thanks to those who have left comments. It has been great to share my learning and then learn more from the questions and ideas left behind.

Finally, I have a new line follow program coming out next week that has become my favorite of all the programs so far. Stay tuned!
