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 (...) (23 years ago, 8-Jan-03, to lugnet.robotics.spybotics)
