  Re: Varying the output voltage?
 
(...) Actually there are four, sort of, as for 0 there are float (contacts separated, infinite resistance) and brake (contacts shorted, zero resistance). The standard firmware switches rapidly between on and float (each cycle takes 8ms), which (...) (21 years ago, 14-Jun-03, to lugnet.robotics.rcx.legos)
 
  Re: Varying the output voltage?
 
This is what I noticed, comparing the two systems with BrickOS One thing that I noticed was at the lower voltages the needle on my multimeter wavered around a little and it tended to steady at the higher power levels All of the readings were taken (...)

  Re: Varying the output voltage?
 
(...) you're right, I forgot float. Thanks for clearing the rest up for me :-) Doesn't the motor itself have a "load" when it works with no actual load? "which reduces power but not speed" Timothy (21 years ago, 15-Jun-03, to lugnet.robotics.rcx.legos)
 
  Re: Varying the output voltage?
 
(...) The power motors that come with the RIS are very efficient, so the load is very light and speed changes very little. Then of course it depend on your robot, if you use caterpillar tracks you will generally have more load than with wheels. An (...) (21 years ago, 15-Jun-03, to lugnet.robotics.rcx.legos)
