Re: Experimental ROV Design using Blue Robotics Components

Hi All,
After having second thoughts about powering the Power Control Board wit a live LiPo battery, I remembered that I have an AC powered 12 amp peak 13.8 vdc battery eliminator, complete with overcurrent and short circuit protection, that I can use to check out the integrity of the Thruster Power cable penetrator cable connections to the Power Junction Board. If all goes well, then I can switch over to the LiPo battery to simulate actual ROV operation.
Good news, there was no smoke and fire when I powered up the 6 Thrusters with the DC battery eliminator power supply which means the bullet connector connections between the Power Junction Board and the Thruster power cables have no shorts or opens.
I then hooked up my trusty servo tester to each Thruster PWM control input and tested each Thruster briefly as to CW and CCW operation and all of the Thrusters were found to be functional.
Now I can setup the Navigation controller and see if I can use the Gamepad along with QGC to command the BBBMINI to drive the Thrusters.
More to come.
