1.1. Research Motivation and Purpose
Humans have been imitating nature since time immemorial. Just as people in the primitive age made bows and arrows by looking at the sharp claws of predators, and Velcro was made to imitate a goblin needle, imitation and humans are inextricably linked. In recent years, the imitation of nature has become a field with a wider and deeper academic scope. That's biomimicry. Biomimetic engineering, which explores tools and new technologies necessary for life by imitating basic structures, principles, and mechanisms of animals, insects, and fish, including humans, is also being actively researched amid changes in scientific trends. Biomimetic engineering is a science that imitates nature, so we can expect to see places we have never been on Earth. Among them, the sea accounts for 70% of the earth, but only a few are known due to technological limitations, and recently many new energy resources, such as manganese nodules and gas hydrates, have been discovered in the seabed, helping to improve national competitiveness. Therefore, biomimetic underwater robots are receiving a lot of attention as they can explore the unknown world and the seabed with high potential economic value.
A typical biomimetic underwater robot uses a screw to get power and move. Here, a screw is 'a helical groove cut on the surface of a cylinder. In order to pump water, etc., or to compress air, the engine produces a linear force while rotating in a cylindrical space. However, the screw has a short lifespan as it frequently breaks down due to floating objects such as seaweed or seaweed. So, while our group was exploring, 'Isn't there a way to solve these problems without using a screw?' It was discovered that the direction of movement was controlled by moving the funnel that spouted water, gaining momentum according to Newton's third law (law of action-reaction) while expelling it. We wanted to create an underwater drone that mimics the movement of fins to produce an underwater drone for low-noise and stable filming.
