Abstract
According to one embodiment of the present invention, a method for adjusting a position of an object to compensate for tilt includes providing a rotatable base supporting an object and directing the object relative to the base such that the position of the object is controlled relative to a first axis. The object is stabilized along a second axis. The object is positioned relative to the base using first and second bearing arms. The first and second bearing arms movably couple the object to the base at a first position relative to a third axis and a fourth axis. The first bearing arm couples to the object at a first pivot point. The second bearing arm coupled to the object at a second pivot point. Each bearing arm includes a first portion and a second portion, which are coincident with the third axis and fourth axis, respectively. The object is adjusted to a second position using the first and second bearing arms to maintain the first axis when a tilt angle of the base is detected.
