C5.2: How can we use Colored Tape in a Line Maze?
In this tutorial you will learn how to use colored tape in a line that can be used for line-following by a LEGO MindStorms EV3 or NXT robot. The tape used is plastic electrician's tape. The advantages and disadvantages of this type of tape were discussed in Part 1 of this tutorial which you can see here. To demonstrate that this type of line can be followed, the video shows an EV3 robot that follows a line that changes color. A method is shown that allows you to choose which color can be followed by your Robot, and which color can be ignored for line following purposes. This is part 2 of a four-part tutorial about setting up tape line circuits and walled mazes for Robot line following.
