Lol I googled the problem and it is mentioned in several docs,

but from what I gather I only have two program statements to work with to figure out how to make the S1 follow the blue tape line.  Do I have to come up with an algorithm on my own?


It is shown in the promo videos but how is it done?  Thanks!

All the blocks needed to implement Line Following can be found under the "Smart" heading in the Scratch environment.

GReat!  But, it's not very straightforward.  This is all the information in the universe (according to google) that exists about this topic:

Note:
The format for line information is as follows:
The first item is a fixed number 10, which represents the points in the line detected by the robot. The second item, Info, is information about the line returned by the robot (in which 0=no line, 1=single line, 2= T-intersection, 3= 4-way intersection). The third item is a group of 4 numbers: X-axis (for points ranging from near to far), Y-axis, θ (actual tangent line) and C (or curvature, in the value range 0-10, with 0 representing a straight line). Altogether there will be 42 values.

So how do I use these values?

Note:

In the Robomaster App, select LAB, select ROAD TO MASTERY then select HUNTER. Its a tutorial that will help you out.

The programming guide actually has a full scratch example for that unter the "set exposure value to (high)" entry in the Smart section.

Here is a video I created of Chip running a slightly modified version of the Scratch Hunter program.
At 1 m/s, the speed of the RMS1 was way too fast for the test track I had created, so I cut the speed in half, to 0,5 m/s.
Note that the program terminates when it reaches a fairly steep curve in the track. My next step will be to see if I can use the curvature parameter in the Line information block to enhance the program.

for some reason am unable to place the identified line info command inside the set LineList to? anyone have this issue? bug maybe?

Thanks for sharing this
