Title:
FLOATING BODY STRUCTURE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/112246
Kind Code:
A1
Abstract:
A floating body structure 1 comprises: a floating body 30 that can move by floating on the water surface; and an internal mechanism 10 that can move on the floating body 30. The floating body 30 comprises: a frame 31 on which the internal mechanism 10 moves; and propellers 33 for moving the floating body 30. The internal mechanism 10 comprises: a horizontality-maintaining platform 11; a V mechanism 13 that supports the horizontality-maintaining platform 11 and can be extended and contracted in the vertical direction; an H mechanism 14 for moving the plane inside the frame 31; and a control unit 15 for controlling the V mechanism 13 and the H mechanism 14 in order to keep the inclination and position of the horizontality-maintaining platform 11 in a desired state.
