Making a line-follower test track
Since you will be making your robot follow a line, we need to start with a section of line to follow. The track will be used at the beginning to test our line detection algorithm and can then be extended to more exciting tracks when we turn on the motors and start driving along the line. What I will show you in this section is easy to make and extendable. It allows you to experiment with different line shapes and curves and see how the robot responds.
You can even experiment with different color and contrast options.
Getting the test track materials in place
The following photo shows the main materials required:

The photo in Figure 14.2 shows a roll of black electrical tape on a large sheet of white paper. For this section, you'll need the following:
- Some A2 plain white paper or board.
- Some black electrical insulation tape or painter&apos...
