Jessiko robot fish

JESSIKO is an underwater robot which uses fins to move through the water. The project started in 2005, when Christophe Tiraby, an engineer in the industry, confirmed the feasibility of a small robot fish with the ability to swim autonomously for hours. Since then, several versions have been built, currently V5, the first series version manufactured for Yeosu World Expo. JESSIKO is a highly sophisticated innovation with 3 international patents.
