24226Re: [SeattleRobotics] Does anyone know of a Servo Control Authority?
- Jun 1, 2005Almost all of the RC servos on the market today use the signaling
protocol that tbrenke@... described earlier: a 1-2 millisecond
pulse repeated 40-60 times per second; a 1.5 millisecond pulse tells
the servo to move to center. Futaba and JR have different opinions
about whether a longer pulse means clockwise or counter-clockwise
rotation, but other than that they're all compatible.
There are many good web pages out there that explain the details, here's one:
There are a few servos on the market that support much higher
signaling rates - high-end servos intended for use with gyro sensors
for tail rotor pitch control servos for RC helicopters. Most of those
are still backward compatible with the signaling described above - the
Futaba 9251 may not be, but I'm not certain.
