An active Camera Gimbal

An active mount allows guiding of the camera in the necessary direction, in spite of the position of the model. Usually such platform is provided with two axles - the panorama and the tilt. The direct drive from the standard servo-mechanisms is used for the light cameras. It is an often case, when the servo-mechanisms with the increased tilt angle are used. Also the active gimbal may be used for stabilization of the camera. The gimbals, provided with three axles, are used for stabilization - the pan. (Z), the roll (Y) and the tilt (X). Pay Your attention to the fact that some gimbals, provided with three rotation axles, secure the possibility of stabilization in certain positions only along two axles. It happens so, if the axles of the gimbal get combined. For example, pay Your attention to the gimbal, where the camera is installed inside the rotating transverse ring. If the camera is turned downwards, the axles of the panorama (Z) and of the roll (Y) will coincide, whereas the lateral swinging of the model will pass to the camera. Presence of the rotating ring around the camera is the most complex and unreliable point of such constructions. The purpose of this ring is to secure that the center of the mass of the platform remains in the same place in the course of rotation along all axles. The ring rotates according to the principle of the large bearing, but it is produced out of the light metal. Deformation of such construction caused gaps and...Continue Reading
