A couple of very quick photos of the hybrid - bit of wiring work to be done tomorrow to connect the thrusters then water testing to sort out buoyancy and balance.
Basically -
Chassis is longer for better fore/aft balance
Batteries are easier to swap
Uses T100 thrusters now
More robust
Easier to attach payloads etc to
Will make it pretty once we sort out the functionality - amazing what you can do with a few cutting boards and assorted stainless fasteners
I probably should update this thread seeing as how it has been revived. The hybrid ROV handled well - stability was very good, but we found that a three thruster ROV was just too limiting/frustrating, and we had a lot of annoying electronics issues and so purchased a BlueROV2, and then a second oneโฆ - one has had some additional cameras fitted by Etienne at DeltaROV and they are working well too. The support from KevinK and everyone at Blue Robotics has been very appreciated.
