  This code looks suspiciously like the FastIRRoaming code.· You should expect a little jerkiness from this code but more speed in the adjustments.· Plus it should only be jerky when it detects something.· So it's possible you have the sensors aiming downward too much if it's doing this when there's nothing there.

  yeah, it is pretty much the fastIR code. I thought that I might have done something wrong because of the jerkyness....
  
  I was looking at this for quite awhile and wanted someone else to look at it, in case there was something that I was missing.
  
  Thanks,

  You can completely eliminate the jerkiness by incorporating ramping into your Boe-Bot's maneuvers.· Here is a link to an example program with a ramping subroutine: EepromNavigationWithRamping2.bs2.· For more information about how this program works, see the·Ramping in Navigation section·in·Boe-Bot® Robot Navigation with Accelerometer Incline Sensing.· You can find this and other articles·on the Stamps in Class "Mini Projects"·page.

  ...and yes, those connectors are there to hook up more servos...but get a handle on your current problem, first...

  I figured out what was wrong! I had the bot moving towards its obstruction instead of away and as far as the jerkyness goes it is almost eliminated
  
  
  
  thanks for all of your help

  Can anyone elaborate on this? I'm having a similar problem. When the Boe-Bot gets into a corner, it just starts twitching left and right like it can't decide where to turn.

  Hmm.· I had the same problem too.· They were talking about that on another poll.· They said to add a counter of some kind.· I couldn't understand what they ment, so I just changed the part were it would back up to a subroutine that made it turn around.· It worked better/great and come on now, I didn't see the need to back up when the sensers·detected somthing, that almost causes it to get stuck.·

  Can't you have as many servo's as there are I/O's?

  Jake -
  
  Yes you can, but keeping them all refreshed with current positioning information on a regular basis (which is required) is another matter entirely, if you wish to do other things as well. Thus, the evolution of servo conrollers, to take that burden off the microcontroller.
