I'll jump in here. The two canted receptors at the front do indeed give
a basic direction and range finding ability. The IR signal strength follows
an inverse-square law. Double the distance from source to sensor and
the signal is reduced by a factor of four.
As the source is moved to the left or right of the sensor, you will also
get a reduced signal.
By setting up the receivers at an angle, you can take the difference between
the signals form each sensor and determine which side of the Spybot the
source is.

| Yes, your new page is good and what we need. But I immediately have a question: It seems there are two pairs of canted receptors, two at front, and two at about mid-board. This implies there is some inherent directional sensing? I assume at least (...) (21 years ago, 8-Jan-03, to lugnet.robotics.spybotics)
