Syntactic and subsea buoyancy foam and ballast weights for trimming ROVs and AUVs. Choose foam by the depth grade the manufacturer rates it for, then size it from your vehicle's weight in water.

Most ROVs are trimmed to float very slightly, so a vehicle that loses power comes back up. Work out the net weight in water first, then the foam to offset it.
Foam compresses and loses buoyancy past its rated depth. Choose the grade for your deepest dive; deeper grades are denser and give less lift per litre.
