I was thinking about buying one of pololu’s continuous rotation servos but was wondering if a continuous rotation servo could hold its position and offer active resistance if you were to try to turn it, when powered. I know regular servos that have position control can do this because they are applying force to hold at a target position, so I assume that continuous rotation servos cannot do this because they only have speed/direction control and not position control, but can someone confirm this?
The reason I ask is because I am trying to use a continuous rotation servo to turn until a certain force is applied, and then hold at that force value which would be easy if I could tell the servo to stop turning so it would hold its position. I guess if this isn’t possible then the servo would have to turn, stop/reverse turn, stop/reverse etc. repeatedly at a really low speed to make sure the force value is as constant as possible.
