Hello,
well we were wondering if we need two (2) servos with four (4) sensors to sway back and forth or do we just need one (1) servo with two (2) sensors. we are using the code from the kevin.org site. i think the file names are navigate.zip and tracker.zip
I think ir tracking can be accomplished with 2 sensors and 1 servo, but there are two transmitters so the sensors could both be on atthe same time, but the robot is not aimed at any particular emmitter.
It is possible to use only 1 servo with 2 sensors, but that would limit you greatly. First, you’d have to edit the whole code that comes default for IR sensing and tracking. Second, you wouldn’t be able to perform operations like distant management. You would only have 2 corners in the triangle for trigonometric funtions.
Just to clear things up a bit, the code that comes from FIRST (the files you reference), uses two (2) servos with four (4) sensors. Look at http://kevin.org/frc/tracker/ for some pictures of the setup.
