have you used Futaba S3003 and S3102?
« on: September 01, 2008, 12:00:45 PM »
Anyone used the Futaba S3003 and/or S3102 with comments on them? Either break or burn out on you?

Also, does anyone know if the Futaba digital servos hold position when powered (without a signal) like Hitec servos do?

 :) Hello!
I would require more information. When I was in an industrial setting, I had access to information
regarding lots of motors. Do you have a link to the specific motor? Keep me posted.....   ;D

 :) Hello!
 I looked up the motors in question, and they are used in RC boats, planes,
and wheeled vehicles. The reviews on the internet give them a good performance
rating, and they are used quite frequently in robotics projects. I have not located any
reports of burn outs, or, if the motor will hold its position. Will have to look further into it.
Keep me posted......   ;D ;D ;D

 :) Hello!
I have found some information from the book,
programming the propeller with SPIN; a beginners
guide to parallel processing.(page 204)
Futaba servos need to have a pulsed signal sent to them approximately
60 times a second on a regular basis to accurately maintain their commanded
position. If this is not done, the operation of the motors becomes jerky and
irregular. The requirement also means that there can be a minimum worst-case
delay of about 1/60th of a second whenever a command is sent to an R/C servo.
For all practical purposes, a lag this long is not critical in a motor application.
However, you need to have in mind that this delay does exist. It takes
1/60th of a second(worst case) for the motor to start responding to the
last command sent to it.
     The servos have to be reminded of their position about 60 times a second in
order to maintain proper operation, so , we need a way to pulse the servos
on a regular basis 60 times a second.
This programming is assumed to be in every robot that uses these types of servos.
Whew!  ;D ;D ;D
