Well, it's now coming to the end of 2012, so I thought I'd post some information on the current state of play with my ROV design.
No real physical progress, but lots on the design side of things.
It'll just be a matter of raising the funds to get the designs manufactured in 2013 I suppose, we'll see :)
I've just added RS485 to my thruster PCB as I think that a multidrop network on the ROV, when it eventually comes together, would probably be the way to go.
Here's a screenshot of the design so far, it's pretty tight on there and that's just one side of the PCB!
The large through hole DIP IC is a Microchip microcontroller to control the brushless DC motor in the thruster.
On the mechanical side of things, here's an image of the thruster as it stands currently.
I've created a new design for the Kort nozzle that I'm hoping to get 3D printed, depending on cost, then we'll see how it performs in the tank next year.
I've also been looking at the design of the actual ROV (in its very formative stages (see below)) with six thrusters, four horizontal and two vertical.
Putting six thrusters on the design really shows how complex a vectored open frame design can be, but the benefits I think will outweigh the complexity in the end, increased thrust and maneuverability to name but two. Although there's a slim possibility I may go for a three thrustered configuration initially to cut down on costs, we'll see.
OK that's it for 2012, I hope everybody has a great Christmas and New Year, and hopefully 2013 will see some of my ROV plans getting closer to fruition :>
