Hi. I am curious if the EZ-Robot hardware and software might be a good solution as a control system for my underwater ROV that I am building.
Although I have tried to create something using arduino myself, the programming is really a steep learning curve for me.
I will be running a wired Ethernet connection from the surface and have a wifi hot spot in the rov to allow connection to the bv4. It must control 9 brushless esc's. 6 for movement (thrusters) and 3 for a robotic arm. Also one servo for moving the camera vertically. The esc's use the same signal as servo's do, so I don't think this will be a problem.
I will also need to control 3 relays.
I have this unit for sensing battery voltage and current draw: https://www.coolcomponents.co.uk/attopilot-voltage-and-current-sense-breakout-180a.html This can be connected to the ADC pins correct? This is made for 3.3volts, but can it still be used maybe?
I have this IMU from OpenROV that I want to use:

I see there already is support for the MPU-9150 chip. But is it possible to also get the depth and temperature rating from the MS5803-14BA chip?
I want all to be controlled with a gamepad/joystick. This means that multiple motors must react differently to stick movements. For instance, if I want the ROV to turn in place. 2 motors must turn clockwise and two counterclockwise.
Would all this be possible to do?

Back when I tried to get this to work I had a hard time figuring out how to do it. I knew it had to be something along the lines of what DJ just posted but I didn't get it working at the time. Because of "real life issues" of buying a new home and moving I put the whole project on hold and during that time I bought a different control solution that is made for ROV use. That system will go in my ROV and my Ez-b is now the heart of my recently built, fully automatic tennisball launcher for my dog. Way overkill to use the ez-b for that. But since I already had it and it so easy to setup I figured why the hell not. Will post pictures and video of that thing later at some point.
Looking forward to seeing the pictures
. Congrats on the new home!
Glad my explanation helped! Simply set any servos for virtual, and you can receive their values in code. Just remember, if you use the same virtual servo in more than one place it will be overwritten.
