What sorts of results did you get if you tried this project? I come again with my design, it's a scanner, which can display pictures in realtime on the pc screen. Each pixel is written in the rcx, and the pc read this var with spirit.ocx. Each pixel is then displyed in a Timage componnent in Borland Delphi 3. This soft could be easily modified to controll a camera instead of a scanner. However, it takes *huge* time to scan a picture : 10 min! Sequence is : -pc tell the rcx : move + 1 X, store pixel -rcx stores raw sensor data in one var -pc read the var and convert it to 16 levels gray scale (scale adjustable to environment constraints) -pc display the pixel (a 5 pixel square) -do this 50 times, and then move one line (+1 Y) -do this 50 times We get a 50*50 pixels image. see more info's, and source code (nqc on the rcx, borland delphi on the pc): http://users.swing.be/philippe.jadin/ > It seems like a lot of fun! I can't wait to see how the picture turns out. You'll have to wait 10min for each... :-) Phil -- ------------------------------------------------------------------------- Simple yet usefull Robot stuff goto http://users.swing.be/philippe.jadin Votre site internet en un clin d'oeil : http://clairetnet.cjb.net Belgium, Europe -------------------------------------------------------------------------

		Re: Digital Camera with LEGO (and positioning and yadda yadda)
I've been considering something of "the opposite approach" It ought to be possible to use a PC/workstation based digital camera to determine the location and orientation of the mobile, autonomous robot, and then tell the robot its location (and (...) (25 years ago, 2-Feb-00, to lugnet.robotics)

		Digital Camera with LEGO
Of course I've seen the threads going on in here about doing a "Digital Camera" out of LEGO... The idea is solid and seems to make sense. The only problem I've got now is I don't have any way to use the information in the datalog of the RCX. (...) (25 years ago, 31-Jan-00, to lugnet.robotics)
