Last year I built a negatively buoyant ROV crawler, with the idea of “crawling” along the lake bottom for exploration, rather than using a 3D submersible. An early design concept was to eliminate the crawler being tethered to the shore, with the inherent issue of entanglement in bankside and bottom …

Hi @model14 , Sounds like an interesting project! :slight_smile: [image] Richard: I set a limit of 60 feet for depth and attached a 70-foot tether from the crawler to a small (8” X 6”) foam float. On the float was an RC receiver and a video transmitter, plus a battery. On shore a video monitor …
