  IR Tower and USB-Serial adapter
 
Hi, all I have a problem trying to connect a serial IR tower to my notebook. The notebook has no serial port, so I'm using an USB-serial adapter. Although this adapter worked for another device, it seens it is not working properly with the IR tower. (...) (23 years ago, 2-Jul-02, to lugnet.robotics)
 
  RE: Displaying info while debugging
 
(...) Mario, I did some checking and I think the real issue is with the USB driver from LEGO. The serial tower does not exhibit this behaviour. It has its own problems, which include falling asleep after 2 seconds of inactivity. So, as far as I can (...) (23 years ago, 2-Jul-02, to lugnet.robotics.rcx.pbforth)

  RE: optical mouse chips as vision sensors?
 
Since the optical mouse is a miniature camera, the same type of principal could be applied using the Lego Camera, maybe even with a custom template in VC. This would at least be an "all lego" solution (for the purists out there). The focal point (...) (23 years ago, 1-Jul-02, to lugnet.robotics)
 
  Re: optical mouse chips as vision sensors?

  RE: optical mouse chips as vision sensors?
 
One other interesting thing about this idea-- If it works, not only will you get the optical sensor, but you can probably get up to 5 touch sensors and a rotation sensor at the same time. I'm not sure how the signal is sent, but will the RCX be able (...) (23 years ago, 1-Jul-02, to lugnet.robotics)
 
  Re: Navigation using landmarks (Was: Re: lasers and RCX)
 
Just use the bottom half of the mouse, trimmed as much as possible, as a skid plate. It will need to be mounted to allow vertical movement, but it should work alright.

Another idea would be to get a big piece of dry erase (white board). I got a 4x8 ft piece from Home Depot for about $10. Then, your ant could draw all over the 'floor'. You could put a black 'wall' around the edge, to keep your robot inside. This (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

  Re: Navigation using landmarks (Was: Re: lasers and RCX)

  RE: pbForth vs RCX 1.0
