Also, it's important to thoroughly test the robot's waterproofing in various conditions to ensure it can handle the intended application.

For buoyancy, the robot's design must consider buoyancy compensation systems that can adjust the robot's buoyancy based on its depth.

For corrosion, using corrosion-resistant materials and coatings is essential. Regular maintenance and inspections are also crucial to catch any corrosion issues early on.

How do we address these challenges?

Another challenge is maintaining the robot's buoyancy. As the robot dives deeper, the pressure increases, and the robot's buoyancy changes. This can affect its stability and maneuverability.
