Hi :) I was going to write about the need for the minimum of 3 point for a perfect TRIangulation etc.. but then, it just ocurred to me: One can use this err... "BIangulation" (eheh) technic (in theory... I just thought of this right now)) to direct (...) (25 years ago, 30-Nov-00, to lugnet.robotics)

You need gears or a cam that allows an adjustment in the distance from the centerline of the shaft. A 24 tooth gear and a 40 tooth gear would allow you to accomplish such action. I find the cam is very useful as the driven element. You can always (...) (25 years ago, 30-Nov-00, to lugnet.robotics)

Hi, just passing by coming from sci.geo.satellite-nav it occured to me that even under best circumstances and assuming the robot to be on a plane area two microphones will not provide the position, or better said, it still might be on either one or (...)

Oh. I sort of figured that you took the stuff out of the mouse (i just went back and read all the messages ;), it just that I have an optical mouse and i wouldn't want to take it apart. if the rcx could read the outputs from the mouse directly, then (...)

I just got a usb or ps/2 optical mouse (with a wheel!) for $20 at compusa. I'm not sure who is trying to get an optical mouse to work with the Rcx, but i'd like any information on it that they have. Doing a little research, I found out that, when (...) (25 years ago, 30-Nov-00, to lugnet.robotics)
