After abandoning my last ROV design I plan on using a slightly modified "New Design" ROV.I am going to add a ballast system for quick depth changing. I also plan to design a fully compatible manipulator that can be installed easily if anyone else builds the "New Design" ROV. I plan on starting this project in July. I might get the hardware parts this weekend as well.
But...a few questions before I get started building.
1. What motors should I use for propulsion? I would use bilge pumps, but they seem lacking, and since I'm sealing off the motors with a magnetic coupler, they aren't necessary. Brushless motors have weird wiring that I don't exactly understand and controllers for them are expensive and take up a lot of room. Has anyone actually tested and used with success some good brushed motors?
2. From previous built ROVs, anyone have any good tips and suggestions so I don't screw anything up? I have built 1 ROV before, a Seafox, which is not any where close to the complexity of this ROV.
