Hi @bennyboi42
Welcome to the forums! That sounds like a fun project, and a pretty minimal amount of thrusters! Are you configuring their layout something like the “simple-rov” below?
When you mention “flight controller” I assume you mean the Navigator? If you’re using a supported autopilot alternative, that’s ok, but you will still need a Raspberry Pi 4.
You’ll want to flash your Pi’s SD card with BlueOS, and follow our BlueROV2 software setup guide from there!
You’ll basically be connecting your computer to the Raspberry Pi via tether, but for testing can just use an ethernet cable. Your Xbox controller can be used via QGround Control, but Cockpit is an alternative solution for a more configurable software interface.
You shouldn’t need to develop any custom code to get your ROV off and running! Unless maybe you thruster layout doesn’t match any of the available options…
