Looking for some help developing salvage techniques for my survey class ROV. Have an arm and I am hoping to salvage small (less than 100lbs) debris from approximately 100m. I’m looking for a way to take down a small hook or grapple to grab and winch the debris to the surface. Also hoping to not have to resurface with the ROV between debris grabs. Any help or advice on how this might be accomplished would be greatly appreciated.
