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

You might be interested in the CMUcam. See (URL) CMUcam is a new low-cost, low-power sensor for mobile robots. You can use CMUcam to do many different kinds of on-board, real-time vision processing. Because CMUcam uses a serial port, it can be (...) (23 years ago, 8-Jan-03, to lugnet.robotics)

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)
