(...) The RCX doesn't support radar, but the Handy Board with Expansion Board supports the Polaroid Sonar unit... here is a thread on a recent discussion here on it... (URL) Handy Board is essentially the RCX+++, but it does not come in a Lego (...) (25 years ago, 16-Nov-00, to lugnet.robotics)

  Re: The Giant Wheelbot
 
This reminds me of something I was considering building about a year ago, though not out of Lego. (I consider building a lot of things, but nothing ever gets built) I had the idea to build a remote controlled robot completely contained in a sphere. (...)

  Re: any idea if radar can be used with the rcx?
 
(...) Not "radar," but you can couple lights to the drive motors, aim them out front, and use the light-sensor. It will see the reflected light near an object, and react accordingly. On a scout, I make it "avoid light." The thing will get ~ 4 inches (...) (25 years ago, 16-Nov-00, to lugnet.robotics)
 
  Clarification of access control

  any idea if radar can be used with the rcx?
 
hi all Any one has used radar with the rcx to sense objects in front ?? does any one have an idea where i can get small radar sensing devices? in the Mercedees benz S class it uses radar to sense an car or ostacle in front , Dr Patel (25 years ago, 17-Nov-00, to lugnet.robotics)
 
  Another DIY sensor
 
My continuing journey into the world of DIY RCX sensors has lead me to a home made rotation sensor which may be of interest. Since the RCX light sensor reports values in the range 0 - 100 and my compass sensors are thus constrained to report 0 - 360 (...) (25 years ago, 16-Nov-00, to lugnet.robotics)
 
  Re: Turning a robot 90 degrees
 
Hi all, we build a synchrodrive (without turntables) that has a freedom of about 100 degree. We used it in an orthogonal labyrint and it worked well.

  Re: Any one has 2 rcx's?? can a irda prot in a window based machine help in corol of the RCX?
 
(...) No, IRDA is incompatible with the RCX. As another possibility for communication you might want to look at the LNP protocol of Legos. Jürgen (25 years ago, 16-Nov-00, to lugnet.robotics)

  Re: Turning a robot 90 degrees
 
You could let your robot drop a block of white bricks (like 8x8x8 studs bug) and then let it turn until the light sensor on the other side picks it up. you could use a wire attached to the block to retrieve it into the original position. (25 years ago, 16-Nov-00, to lugnet.robotics)
