Homebuilt ROVs Forum

Hello from Ohio! We are a high school build team in an Engineering Design and Development class. We are tasked with collecting some data about our newest project: a homebuilt ROV! We're most interested in creating an active buoyancy system, but we need to take some periphery data for our class, so if you could help us out and provide some basic information it would be greatly appreciated!
Here's our 11 question survey: https://docs.google.com/forms/d/e/1FAIp ... Q/viewform Thank you!


PS: brand new to this forum and this world, so my apologies if I'm in the wrong spot. Any feedback is appreciated. Thank you!
