Here are 9 tips to help make building the BlueROV2 easier and save you time:
Take an inventory of all the parts and components
Use the list included on the BlueROV2 documentation to ensure you have everything you need before starting.
Measure and label the screw packs
Use a micrometer to measure and label the packs so you won’t waste time finding the right parts.
Label the ESC’s
Labeling the ESC’s will help make sure they’re connected to the correct thruster and position on the Pixhawk.
Label the thrusters
Labeling will help prevent connection errors.
Label the electronics chassis (top/left/right sides)
It’s easy to get confused and sides mixed up. Labels will prevent this.
Assemble and test the housings for leaks before wrapping the wiring
Before you connect the thrusters or finish tying up the wiring, be sure to test the housings for leaks with a hand vacuum pump.
Test your assembled ROV in fresh water first
Test your assembled ROV in a fresh water and under controlled conditions. Issues will be easier to identify and resolve.
Instead of removing 6 loctited screws and disassembling the 14 hole end cap,
Remove the 4 screws and 2 aluminum extension bars that hold the electronics tray in place. By removing the electronics tray you have the access you need to the penetrators while not risking damaging or adding dust to the large o-ring.
If you find you have a leak and need to test your penetrators,
Use rubber stoppers (size #000 should work) to plug the holes. They’re cheap and couldn’t be easier to use.
