Coral reefs are known as the "tropical rainforest" and "submarine garden" in the ocean, and they are an important part of the marine ecosystem. With a non-2‰ coverage area, it provides a home for nearly 30% of the ocean's fish to live against the impact of the waves. In order to reduce the risk of artificial coral planting, a machine was designed to assist underwater operators to plant coral and to plant coral independently. Coral planters greatly improve the efficiency of coral planting and reduce the risk to divers.
