One of my servos seems to move in jerks. Even when calibrating, unlike the other servos, which move with each single digit change, one of them will only move if I give it wide ranges.
For instance if I set it to -8 and then to 8, it will move to the apparent correct position, but any lower number won't move it at all.
In push-up mode, since it is installed in the front right shoulder, the right side jerks up and down as the servo jerks between extreme positions, while the other side moves smoothly through the motion.
It cannot really walk, because the one leg jerks about too much, rather than moving smoothly.
Is this just a bad servo, or is there something else I should check?
Hi, please send a video showing the abnormal behavior to support@petoi.com or post it here. We will use it as a proof to request a replacement from the manufacturer.
We already included one spare unit in the package right for this kind of situation. You can swap it on to see if it solves the problem.
