I have a new adder-subtractor chassis. will post the page soon. should be at odin.prohosting.com/...ad-sub.htm but things are not going as well as they should tonight. bearing that in mind, this design is pretty slimlined and all gears are on one (...)

(...) In passive mode using NQC yes. It's RAW format and you have to make the conversion but it works ok. Dean -- Coin-Op's For Sale!: (URL) Lego Workshop: (URL) Lego Club: (URL) (25 years ago, 16-Jan-01, to lugnet.robotics)
 
  Check LEGO set form Mobile Phone

(...) Just the touch and Temp sensor I'm afraid. The light Sensor will work as a passive. (ie no red light). The Rotation sensor won't work at all. Dean -- Coin-Op's For Sale!: (URL) Lego Workshop: (URL) Lego Club: (URL) (25 years ago, 16-Jan-01, to lugnet.robotics)
 
  News sensors and the RDS
 
i am thinking of buying the RDS faitly soon. Do the other sensors lego sells work with the RDS. Thanks Mike out (25 years ago, 16-Jan-01, to lugnet.robotics)
 
  Re: I ordered a 1.5 and was sent a 1.0 Good or Bad?
 
Well, you were lucky. I contacted Lego at the number you gave me and tried to see if they would send me an upgrade as well. They will, but for $25 US ($40 Cdn). Bummer. It's the second time this week. Matthias Jetleb VA3-MWJ (25 years ago, 16-Jan-01, to lugnet.robotics)
 
  Re: Motor mis-match.
 
Why not eliminate the vagueness of RCX's output circuitry altogether by running the motors from a stabilized bench supply set to 9.000 volts. That's is what I did when I characterized all my motors. I measured the rpm and wrote it on the bottom of (...) (25 years ago, 15-Jan-01, to lugnet.robotics)
 
  Re: Motor mis-match.
 
I did it both ways, and got the same results(the order, not in exact speed). I think that the motors are 'tuned' in some way, because random error cannot occur 100% of the time. All motors went slower with the cable turned or the RCX on 'Reverse', (...) (25 years ago, 15-Jan-01, to lugnet.robotics)

  Re: Motor mis-match.
 
(...) Very nice results! Another interesting thing to measure would be differences of the outputs. If you know these, you can put 3 motors each on its output and by changing the sequence measure whether the slowing down in a series is due to some (...)

  Re: Limit Switches without using sensor inputs
 
Very sharp! A very clever and elegant solution to a common problem. (25 years ago, 15-Jan-01, to lugnet.robotics)
 
  Re: Motor mis-match.
 
Thank you! I'm glad to see someone has taken a semi-scientific approach to the whole question. I have one correction/comment to make though: It's doubtful that the Lego motors will heat up significantly enough to affect their operating speed. There (...)

  Motor mis-match.
 
I was having a boring evening - so I decided to test some theories about Lego motors - and at the risk of seeming pedantic - here are my findings: Several times, people on this list have asked why their robots don't drive in a straight line - the (...)
