I hope someone can help me with this. My Boe-Bot cannot get out of corners. Right now, I have the IR configuration set up. I tried the code that is meant for the whiskers in the manual, but it doesn't work. BTW, I am doing high performance IR navigation.roll.gifyeah.gif

    Can you show us a picture of how your IR is set up?· Make sure that they are pointed out to a 45 degree angle from the chassis.

    My first suggestion is to try and straighten up some of the wiring to make sure that it is not interferring with the IR.· Have you ran the IR test to verify that both IR sets are working properly?·

    yes my IR stuff works fin though but sometimes it goes to a corner and the right ir detects first so it turns slightly left, then it turns slightly right becasuse left IR detects and keeps going. I was trying to do the escaping corners code for whiskers frm the manual but for some reason, it failed.

    I havn't looked at the code you have mentioned. But you could try using a trigger to set off a certain action.

    ·ir_det = ir_det + 1
    · if (ir_det >3) then
    ·· gosub u_turn


    ·· Or something like that.... Just my two cents...... [noparse];)[/noparse]

    hmm..i tried something just like that that was in the manual..but it was for the whiskers instead of IR. I tweaked it a little to go along with my bot but it did not work.

    Save your code as a .bs2 file and attach it to this forum thread so that we can look at it and test it.

    I already did on one of my messages @ top ^^ or do you mean the code for the escaping corners in the manual?

    Try experimenting with the "pulseCount" by increasing the value.· Example:

    Change pulseCount = 0 TO 20 to pulseCount = 0 TO 35.

    There is also another pulseCount in code you change under "Turn_Left"

    After looking at your code more closely I noticed that you mixed a few codes together.· Basically you need to adjust the back up routine of the IR so that it doesn't stay focused on the corner.··Write your code so that when the IR detects the object to back up and turn to a complete·90 degree angle and see if this·solves the problem.· Becareful when you mix different codes together, it usually results in oddd behavior.

    You can also try using a do while loop. Like this..

    ····if·(ir_l = 0)AND (ir_r = 1) THEN
    ····· DO WHILE (ir_l = 0)
    ······· GOSUB left_turn
    ·········· LOOP


    ······· This will keep it moving left as long as,(ir_l = 0).
