I have been thinking about building my own ROV for a long time now. I have been working offshore with ROVs for many many years but it is the first one i am building by myself. Atleast an eyeball ROV I got an old TMS(tether management system) control bottle that was scrapped in my company and i have been thinking about converting this one into an ROV body containing all the electronics from the blueROV 2 and to have external cameras. The bottle is anodized aluminium and weighs around 40 kilos on land but is more or less neutral in water. Do you guys think it is too heavy to be operated with 8 thrusters( 4 horizontal, 4 vertical) from blue robotics? anyone have experience with heavier ROVs and the blue robotics thrusters here?
