Line follower robot

Hello, I’ve been using a bit of line tracking/following recently, if you could share some images or additional details,I’d be happy to assist, also is this for a simulator or a physical robot competition?

Depends a lot on the nature of the intersection, and what sensors you have to detect it. It's not hard to have a situation where a 4-way intersection is indistinguishable from a spot where the line simply gets wide.

Hi ,

Actually, this is a closed-loop path. I couldn’t find the exact shape of my specific path, but the stop box is a large black box where the robot needs to stop once it reaches it.

And I am using a straight 5 ir sensors array with 2 N20 600 rpm motors.

Hello,

This is for a kind of line-following robot, I'm not very familiar with it, so I might be wrong in something.

However, my brother already participated in a competition similar to this, but with a different type of robot and, I think, fewer sensors.

The idea I remember he used, and which you could try, is arranging the sensors in an "X" pattern, then, when the three front sensors detect black and the two rear sensors detect white, the robot stops.

Just a warning again, I'm not an expert in this, so I don't know if this will actually work, but it's an idea.

if your robot reacts to DIFFERENCE between two sensors, the intersection will be irrelevant.and so will be short gaps in the line but in your case with five sensors, you would not are about gaps. yol would stop when none of the sensors sees the line.
