Abstract
Official abstract text for this publication.
A three dimensional wire flying system includes a plurality of winches collectively hanging an object and a control unit for controlling the plurality of winches and the main safety device. Each of the plurality of winches includes a drum unit, a wire wound on the drum unit, a motor unit which provides power to the drum unit, a brake module which stops rotation of the drum unit, a limit switch which operates upon detecting a hardware limit state, and a servo-system. Each of the plurality of winches operates to move the object in a three dimensional space in three directions, including an up-down direction, a left-right direction and a forward-backward direction, and each winch provides a multi-level safety protection.
First claim
Opening claim text (preview).
What is claimed is: 1. A three dimensional wire flying system comprising: a plurality of winches collectively hanging an object; and a control unit for controlling the plurality of winches and the main safety device, wherein each of the plurality of winches includes: a drum unit, a wire wound on the drum unit, wherein a length of the wire unwound from the drum unit is adjustable by unwinding the wire from the drum unit or winding the wire on the drum unit; a motor unit w…
