19. Buoyancy Calculations
The surface area of the plates provides the ROV with the need to remove material to satisfy weight standards if needed.
Side slots allow for cross elements to be easily adjusted.

38. Lessons Learned Manage your cost!
Funding and design should be simultaneously managed.
Mitigating high cost.
Switching material sizes.
Teamwork!
- Communicate and divide the project into portions.
- Make sure everyone knows everyone else's job.
Organization
Maintain to do lists between team members.
Meet deadlines placed on each other.
