Abstract:
A six-degree-of-freedom travelling system provided with a solid serving as a travelling object having eight connection points; eight lines suspending said solid in connection with said respective eight connection points to be hauled up and veered out: and three fixed points for guiding said eight lines therethrough consisting of a top fixed point disposed above said solid, a right fixed point disposed rightward from said solid, and a left fixed point disposed leftward from said solid, wherein said right and left fixed points are laterally-symmetrically disposed with respect to said solid when said solid is originally positioned, and said eight connection points consisting of:a first connection point and a second connection point disposed forward and backward on the top of said solid, two of said eight lines in connection with said respective first and second connection points being extended through said top fixed point; a forward upper third connection point, a backward upper fourth connection point and a longitudinally-middle lower fifth connection point are disposed at rightward portions of said solid, so that said three rightward connection points are arranged so as to form an isosceles triangle with said fifth connection point as the bottom vertex thereof, three of said eight lines in connection with said respective third, fourth and fifth connection points being extended through said right fixed point; and a forward upper sixth connection point, a backward upper seventh connection point and a longitudinally-middle lower eighth connection point are disposed at leftward portions of said solid, so that said three leftward connection points are arranged so as to form a vertically-flapped isosceles triangle with said eighth connection point as the bottom vertex thereof, which is identical with said triangle shape made by said three rightward connection points, three of said eight lines in connection with said respective sixth, seventh and eighth connection points being extended through said left fixed point, wherein said third and sixth connection points are disposed laterally and symmetrically with respect to said first connection point, and said fourth and seventh connection points are disposed laterally and symmetrically with respect to said second connection point.
