 | | DC motors vs. servo motors
|
|
The nature of the PWM (pulse width modulation) is entirely different for servo's vs. plain DC motors. For a DC motor, it has a two wire connection. All drive power is supplied over these two wires -- think of a light bulb. When you turn on a DC (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

For servo, there is a certain threshold duty cycle (say 50%) of the PWM signal, where anything above this threshold will make it to run forward, and less will make it to run backward. So, you still need to apply the PWM even if the servo is not (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

Hello, Does anyone know if the Rug Warior Pcode run without the LCD? (Pcoderwl.S19) If not : 1 is there another RW pcode that will run without the LCD? I using the RW pcode on my Fingerboard II with out the LCD and I think this may be an issue. (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

That did answer my question. I am not familiar with servo motors, I have only used plain DC motors. I am also familiar with PWM. I was just unable to determine if the same PWM signal that drives plain DC motors could also drive servo motors. From (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

it's easy: just use the replacement pcode_hb.s19 file provided by Kent Farnsworth: (URL) your message you said: (...) and still have the HB work.

(...) As I've said, I think the new Lego Technic gear motors are a great deal. They're inexpensive (about $18 each), they seem to be quite efficient, and they run well directly from the HB power supply. If you're building your robot out of Legos (...)

I was just wondering if there's any way to disable and remove the LCD screen and still have the HB work. My design does not require the LCD, so if i could remove it my robot would then be a little more balanced. Every time I remove the LCD my (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

(...) What you have is most likely a 9V DC motor, not a servo. As far as I know, there is no such thing as a Lego servo motor. The four-contact plug is a Lego standard that allows changing the polarity simply by rotating the plug 90 degrees. There (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)
