In this thesis, we aim to combine interactive manipulation technology with digital fabrication for
un-derwater expression.
To achieve this, we introduce a new method to add the controllability to underwater objects applied
by a structure of a Cartesian Diver. The Cartesian Diver is a well-known demonstration of Pascal's
law and Archimedes' principle. The diver is able to be manipulated to achieve up and down motion
by a single external force to the primary container based on water pressure changes the overall
vol-ume of the diver or the volvol-ume of air in the cavity within the diver.
For this thesis, we develop a system setup to manipulate the divers; the length of the tank is 400mm
and its diameter is 150mm and water pressure can applied it up to 200k Pa. We successfully
de-signed and manipulate the object by our method.
We discussed the principles and methods to create a digitally designed and fabricated the diver and
to stabilize it in the middle of water, then developed several applications: various shaped object,
floating screen and the object has function of messaging.
Our work combines digital fabrication technologies with non-contact manipulation that uses the
space transmission power of the object around it. We believe this combination extends the
possibili-ties of new underwater expressions at many places such as theme park, public areas and our daily
life.
