Embodiments of the invention move objects throughout two-dimensional and
three-dimensional space by using a movement line that is coupled with a
plurality of opposing sides of the platform. The movement line is used to
control the horizontal axis motion and Z-axis motion of the platform and
is designated the horizontal movement line. Displacing a portion of the
horizontal movement line allows vertical displacement of the platform to
be traversed. There is no need for a complex computer control system
since the Z-axis displacement is substantially independent of horizontal
movement over a coverage area serviced by the platform. Nested
embodiments utilizing one or more rope allow for three-dimensional
movement of an object or angular displacement of an object with respect
to the vertical axis. A mounting beam for positioning and supporting the
Z-axis and horizontal axis motors and visual display element(s) and other
optional multimedia devices may also be positioned independently of the
platform. In addition, since the line may be commanded from one point,
distantly located motors and electrical cables are not required. Many
types of useful devices may then be attached to the platform including
devices that require external power or devices that possess their own
power and are operated via wireless signals.
