Line Tracking VI. drives in half a circle...?

[Ethan Spitz]

Hmmm. Try writing code to see if you man say make a wheel speed up when you cover the sensor or it sees the line etc.

Also the sensor should change from green to and orange red light when its on the line. Does yours do that?

il try the make a motor spin if reflected.

and yes it does change colors and it does show up in the drivers station under gpio state..

Ok, let me know what happens there. IF it doesn't work, I would recheck the wiring. And calibration cause that would rule out the programming problem.

it works; whats the problem with the default code?

[Ethan Spitz]

Thats a good question . We just erased it and wrote our own code from scratch. I would suggest that since the default code isn't working.

Ethan

are you willing to help us develop?

[Ethan Spitz]

Sure. Basically you want to create nested case statements for each combination you can get with the light sensors.

How many sensors are you using? I suggest programming 2 and then adding in a 3rd after you finish that.

I would be more than happy to help you if you would like. I could give you a basic example of what the nested case structure could look like. Shoot me a PM and ill get right on it.

Thanks For The Help Everybody... when i get this code semi perfected il post it for the teams that needed help just like us... we got it to track the straight line good enough

The default code wants you yo use the black wire, not the white. You can just invert the signal in the tele op code and I bet it works.

Could you please provide a screen shot of your code as to how you would recommend programming the wheels to turn?

[Ethan Spitz]

It has case statements heavily nested in it so it won't be to much help. Basically we said if both sensors are off the line go straight, if left sensor is on the line make the right wheel spin a little faster till its off. If right is on the line, make the left wheel spin a little faster.

The middle sensor stays on at all times and if all of them end off the line, it knows which sensor saw the line last and turns that way.
