The most effective 2 sensor Line Following setup

In this video, I test a new color sensor setup where one color sensor is on the front of the robot, while another sensor is on the back. This new setup is aimed at reducing the swaying motion found in many 1x sensor line following programs, which would greatly increase the consistency of the angle the robot is facing while following a line. Although this setup works great, it should only be used if you have a 3rd color sensor, as it simply finetunes the consistency of line following.

I think this is a great idea, but I do have 1 thing to mention. I am not sure in a practical match, that you want to permanently put the back light sensor there. There are 2 reasons. The first one is that you permanently take away 1 extra sensor port, now 3/4 of the ports for just line sensing. The more important reason though, is I think you only get the option to follow the line the way you describe in the video on one side of the line, and only in 1 direction. I think this idea really works well with a third light sensor that is on an attachment, which gives you much more flexibility on where the lightsensor goes, what direction you get to do the linefollowing on, what side of the line you follow, what side of the robot follows that side of the line. I don't think you want to commit that before you build any attachments. How well does this work when the line turns or curves?

@Matt So, I think the sensor attachment is a great idea. This setup doesn’t work too well for lines with sharp turns since the back sensor is solely there to correct the robot if it isn’t directly parallel with the line, but is able to follow lines that curve.

@@brickwise8624 That is very cool! I hope to hear about more ideas like this because I have definitely not seen this done before actually.

Great Video! I just want to know if you would be willing to share what website you use to show us the lego designs.

That's a really innovative idea. Did you use a proportional line-following algorithm to use the colour sensor at the rear? How did you integrate the two line-following programs to control the same set of wheels? Was one given more weight?

Yes, both sensors use a proportional line following program where they compare the sensor reading to a target value. The front sensor contributed 90% to the overall steering value, while the back contributed 10%
