A hundred million tons of microplastics contaminate the ocean. Besides causing environmental pollution, microplastics are also ingested by plankton and fish and transferred up the food chain to humans. Submersible robots can be equipped with tools to capture microplastics as they enter the ocean and assess potential environmental hazards. During long underwater cleanup missions, flow disturbances and energy consumption are inevitable concerns. This work investigates how rotating a top-mounted, two-axis rudder allows an underwater vehicle to adapt to water flows and optimize energy consumption. The proposed robot can increase its travel speed with or against flows by self-adjusting its rudder rotation........

Key Words: Two-axis rudder, incident angle, self-adjustable, flow adaptation, energy optimization.
