Well my code does make constant calls to printf() and motor() (although
with the original PWM code). I did notice the jitters more on the low end.
now I've put aside the head rotation and sonar routines and will start
on the encoders. I am interested in using the servo as a head mounted
sensor platform in order to perform tracking. The idea is that by
sweeping the head a sensor map (sonar, pyro, beacon) is created and a
heading is chosen. Does anyone know of a good resource for the types
of algolrythms involved in sensor mapping...
Thanks for the reply,

My HB is totally new, and I also have the "jitters". However, I have never
Zap charged the unit. Although when we observed the jitters we were
excessievly calling printf()... We more promenently noticed the jitters
when
running 2 9V motors (with smooth PWM code). The jitters only occures
in the
range 20 - 30... You can probably best notice this by using the knob to
set
the PWM rate of the motors directly...
