Best SpikePrime Line Follower Sensor Strategy

[@Classe1F273]

Hi, could you please help me find the solution? I have 2 color sensors, one is set to reflex for line tracking. If the black line is discontinuous, how do I proceed?

Hi There! I will need more information to be able to help you, can you email a photo of the line you are trying to follow? Also, have I understood correctly that you are using just one light sensor for the line follower? Is it a proportional line follower or fast/slow?

@@why-not-bot it's line proportional whit sensor in B. then senson in A is in color mode and sees green with counting, the second time it commands to go back. so he resumes the line follower until he reaches where everything is white.

My email is [e-mail] Maybe a photo of your line follower coding as well!

Hello, could you please tell me what 2.86 is. If I use medium angular motor this number changes? Thanks

[@why-not-bot]

Hi, the value 2.86 depends on the diameter of the robot wheels and the distance between the two driving wheels. My robot has wheels of 5.6 cm diameter and distance between the wheels of 16 cm. The ratio 16/5.6 is 2.86. To turn the robot through 360 degrees the wheels will have to move by 16π cm. If you turn the motor through 360 degrees the wheels only move by 5.6π cm so you have to multiply by the ratio. I hope this explains it!

I am pleased I could help you!

​@@why-not-bot Excuse me for the second question, Sir. At minute 6:27, we can see how the robot slightly veers to the left when the junction is of that type. How could this be corrected? Perhaps by having it follow the line on the right and then, after completing the turn, making it follow the line on the left? Thank you.

@@davidezeppa384 Hi, thanks for your question. I have looked closely at the video and see what you mean. I should have followed the right side of the line here, you are correct. The kick to the left happens after the move 5.5 cm block, this block is not a line following function, just a basic movement block so I do not see a reason for the kick to the left. I still have the robot so I can look into this although it will be a few days as I am away from home at the moment. It might just be the first part of the spin turn to the left which is the next block executed! Thanks for your feedback
