Flexible floating apparatus and manufacturing method thereof

Abstract

A flexible floating apparatus has a flexible bone structure and a floating cover. The flexible bone structure has at least a first joint part and a second joint part. The first joint part and the second joint part are connected with a first resistance force to keep a relative position between the first joint part and the second joint part. A floating cover is made of buoyant material wrapping the flexible bone structure. The shape of the floating cover is changed when the relative position between the first joint part and the second joint part is changed.
