control of 360 degree servos

Former Member over 12 years ago

Hi

i wonder how i would control a 360 degree servos from a python script?

there are lot of guides on 180 degree servos

most of them from adafruit... have nothing against them but i like to not be dependent on external libs

i'm going to use this in a fully automatic tracker.... the tracker will be used to track high altitude baloons (30+ km)

Hi Bo,

A servo capable of 360 degrees would be different from those "modified RC servos" that give continuous rotation. Are you planning on using this for a gymbal type mechanism to track?
If so, perhaps PWM is not the best way to do this, especially if you're going to the mechanical effort at producing a gymbal.
A better choice would be to use geared-down stepper motors for much higher resolution.

nope... it will be a simple up/down with one servo and left/right with another.... one limit will be that it can not go from 360/0 to 1... it will be told to go the other way round to not mess up wires

up/down will be limited to 90 degree up and no down...

and i will better stay on servos... cheaper... just need the big hobby servos... then a few bearings to take load off servos

Have you got a URL/datasheet to a 360 degree servo that you're planning to use? Modifying a 180 degree servo for continuous rotation is not the same thing as a servo capable of a controlled 360 degrees.
