The project focuses on designing and developing a supercritical foamed 3D-printed biopolymer-based Remotely Operated Vehicle (ROV) intended for diverse applications such as oil spill recovery, drowning emergency rescue, swim assistance, and surveillance. The ROV's biopolymer composition ensures environmental sustaiNobility, while the supercritical foaming technology provides lightweight yet durable construction for efficient operation in challenging underwater conditions. The multipurpose ROV can be deployed in critical situations, offering swift and effective responses for rescue missions and environmental protection. Its versatile design promises advancements in both safety and ecological maNogement.
