Underwater Soft Robotics for Coral Reef Rehabilitation and Marine Habitat Engineering

Coral reefs, often referred to as the "rainforests of the sea," play a critical role in maintaining marine biodiversity, coastal protection, and global ecological balance. However, climate change, ocean acidification, and anthropogenic activities have accelerated reef degradation at an alarming rate. Traditional methods of reef restoration, such as manual transplantation and artificial reef deployment, are labor-intensive, expensive, and often limited in scale. Recent advances in soft robotics present a promising solution for underwater ecological engineering. Soft robots, designed with flexible and adaptive materials, can mimic marine organisms, navigate fragile ecosystems with minimal disturbance, and perform precise tasks such as coral transplantation, debris removal, and microalgae seeding. This paper explores the potential of underwater soft robotics in coral reef rehabilitation and marine habitat engineering. It highlights the design principles of soft robotic systems for underwater applications, including bioinspired locomotion, compliant actuation, and material resilience under high-pressure aquatic environments. Furthermore, the study emphasizes the integration of soft robots with environmental sensors and autonomous navigation systems, enabling large-scale and sustainable reef restoration efforts. By bridging the fields of marine biology, material science, and robotics, underwater soft robotics has the potential to revolutionize marine ecosystem conservation and ensure the long-term survival of coral reefs in the face of global challenges
