Abstract

The recent aquarium arts simultaneously provide visitors with interest in science technology and fish ecosystems. In particular, some studies on soft robotics develops some fish robots with a feeling similar to reality. These robots have the potential to be a new life that can coexist with human and actual fish. This study aims to develop a soft fish robot that allows people to directly contact and control swimming easily. We introduce 3D printed mold, magnetic soft fish mixed with silicone rubberizing reagent and sand iron. The concept of real fish swarm using magnetic field is proposed on this paper. In this paper, we show a basic follow-up of fish robot and verify soft fish swarm by moving magnetic field. The results reveal that the fish robot follows the magnet due to the magnetic change of the sand iron inside the silicon. Refer to the principle of boids, the fish swarm shows that the dynamic mutual interference between fishes by magnetic sand iron can be described as a cohesion of magnetic force, separation of collision and alignment by a water flow.
