1. *Efficient Movement:* Understanding hydrodynamics helps in designing robots that can move efficiently through water, minimizing energy consumption and maximizing speed and maneuverability.

2. *Stability:* Knowledge of hydrodynamics is crucial for ensuring that underwater robots remain stable and can maintain their position or trajectory in water currents or turbulent conditions.

3. *Drag Reduction:* By optimizing the shape and surface characteristics of underwater robots based on hydrodynamic principles, drag can be reduced, leading to increased speed and energy efficiency.

4. *Control Systems:* Hydrodynamics influences the design of control systems for underwater robots, enabling precise navigation and maneuvering in complex underwater environments.

5. *Environment Interaction:* Understanding hydrodynamics helps in designing robots that can interact effectively with the underwater environment, such as sampling water, collecting data, or performing tasks in marine ecosystems.
