Yes, I think the point isn't whether or not the robot has enough oomph to recognize faces or things like that :D The point is that you can do a *lotta* fun stuff with a camera or mike in a robot, if ONLY you could give the RCX a link to something (...) (23 years ago, 7-Jan-03, to lugnet.robotics)

This is interesting information, thanks TJ. I must say that I got the visual impression that the buggy motors seemed to have more than a mere 2 - 3 times more shaft power output than the gear motors. The little piece of data which would add greatly (...) (23 years ago, 8-Jan-03, to lugnet.technic, lugnet.robotics)

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.
