Orange object has 3 degrees of freedom in its planar motion: two linear and one angular displacements.
This mechanism can deal with two linear ones.
For object center A(x,y):
Left motor controls x value via screw-nut drive.
Right motor controls y value via rack-pinion drive.
Angular position of the object is unstable and needs a control device (not shown).
For angular control devices refer to:
