Servos going to first position in a violent way.
November 12, 2010
This is an open question on the problem of the violent twitch/swing servos have when they are first turned on and when they get their first position command. The obvious answer is to always finish a "session" by centering all your servos and then turning off, but this assumes that nothing is going to get bumped or creep out of "centered" while waiting for the next time it will be turned on. One could also center all the servos by hand (with the servo unpowered) but I have never cared for moving servos by hand if I can avoid it.
So the question is: How can you get your servos from "off" to "first position" without that full-speed, violent swing?
