Ok all I going to share some ideas. ok I think the most important upgrade we can make on the C model it’s to pull up the WiFi link and the application. Ok this is what I propose to Costas and all of us her.
On board(ROV) 1Raspberry Pi 4, the 2 motors drivers, 1 battery , the new camera, the batt balance outside of the sphere to recharge without open the sphere. Between the ROV and the surface the Ethernet cable in a floating house and on the shore this Ethernet cable plug in another raspi and on that raspberry on Xbox joystick and one 10” HD screen in a small suitcase. No WiFI no App the good old cable and Hardware. Ok guy’s let me now if you agree. I hope my english is not to bad and you understand what I looking for.
Nice idea! I'm thinking about an upgrade to just move the battery outside the sphere as I'll be using the ROV from a boat in a salt water environment and nervous about having to open the sphere to swap out the battery to often. Maybe also to increase the battery capacity but appreciate any thoughts about this.
