I am pretty sure it won't since (i think) servos have to run through a stepper motor, correct? What I am trying to do is make a prop where her head will spin 180 degrees and then stop. I do not want to run this off of the computer though. I want to make this a stand alone prop. This is my idea. I am going to make a "wheeping widdow" and have her crying as people walk up (her back to the people) . Then she will stop crying, head spin 180 to face the people, then use maybe either a sciccor type mechanism or just one that makes her jump at them. When she comes back to the start position, her head will turn back around. Any ideas?
