Hi Guys, First blog post but long time looker on OpenROV, awesome work.
Im lucky / unlucky enough to work with ROV's for a living in the North Sea in the Renewable Energy and now Oil and Gas in the UK, I work with ROV's as small as the Video Ray, to a Seaeye Falcon, to a Sub-Atlantic Mohawk up to a Perry XLS
I'm currently designing and getting the ground work down for a home made ROV to explore some of the shore based wrecks around Orkney and eventually something gutsy enough to explore the wrecks in Scapa Flow.
Currently thinking on making the first vehicle Battery powered (I've seen autonomous vehicles like AUV's and AIV's use LiPo's to great success) and using arduino with a shield for thruster control, that means learning arduino but keeping the camera to a simple mini CCTV at least for the beginning,
The need for micro-controlled thrusters is quite high, variable power thrusters brings an immense degree of control compared to on / off of thrusters so for the initial design that's the main design point. Preferably I would like 4 lateral vectored thrusters all working at the same time with one vertical thruster but I need to do my homework on the limitations on Arduino boards etc, worst comes to worst I'll just go for the 3 thrusters
I'll post on my findings etc and progress but any and all input is extremely welcome :)
