I'm trying to build a stabilized platform for a camera. No matter how the base is perturbed (linear or angular), I need the camera to remain pointed along the same vector. I'm assuming that the camera is free to rotate inside a gimbal.
I understand that if the camera's CM is located on the gimbal's axes, then small linear disturbances should have little effect, but the camera will rotate due to even the tiniest rotational distrubances.
I also understand that if the camera's CM is suspended beneath the gimbal's axes, then small rotational disturbances should have little effect, but the camera will swing due to even the tiniest linear disturbances.
So my solution is to place a downward facing gyro at the center of the gimbal's axes, with any remaining camera and other mass balanced at the same point. I believe I only need the one gyro because the pan direction does not require stabilization and will not be part of the gimbal.
Does this sound right?
