Modifying Servo Motors

mark0127

I recently bought two Futaba BLS351 digital servo motors.· Is there any way that I can modify them for continuous rotation without removing the potentiometer?

Program your microcontroller to tell the servo to go to center, and move the pot until it no longer moves. After this, remove the part that turns the pot and search for areas on the gears that would stop it from moving past 90 degrees and cut it off. Now your servo is a continuous rotation one. At www.societyofrobots.com there is a tutorial somwhere if you want to look at it.

+1 to Pi. You don't really 'remove' the potentiometer, instead you set it to it's "center" position (so a 1.5 mSec pulse will be a "stop" command) and then disconnect the potentiometer shaft from the gearing. Oh, and shave the gearing so it will rotate continuously, off the shelf the gears have 'stops' that prevent this.
