After presentation of the bi-axial joint (see Biaxial coupling and Active biaxial coupling), here is an original example of a mechanism which use it. You have to remark the perpendicular orientation of active bi-axial joints, and the spacer under the passive bi-axial joint. This arrangement on the base triangular plate keeps the spatial centers of rotation at the same level - here in the corners of an equilateral triangle. The upper joints on the mobile triangular plate have their centers of rotation placed on an identical triangle.

The main effect is that the mobile triangular plate has always a parallel position (here horizontal), no matter what is the angle of the coupling rods.

Using two stepper motors and gears to combine the rotation of the keyed axles you can move a video camera in certain positions on desired path. A third stepper motor can be placed on the upper plate to be used for rotating the camera around the vertical axis. This would be a total control - CNC with 3 axes.
