My ROV team has run into some trouble. We have just taken eight t200 thrusters with blue esc and stripped and soldered them to cables that will connect onto our ROV. The trouble we are having is that three of our thrusters are not be working any more. Here are some details that might be helpful.
We tested each motor with 16V using and arduino uno with i2c to control them. We soldered each of the thrusters onto cables first and then tested them. They were tested with the example arduino library written for the motors. We did not test the motors before we connected them to cables, but we assumed that each motor would work because we had not taken them out of the boxes before we tested them.
The odd thing is that some of the motors worked for a little bit and then later they suddenly stopped working. Whenever we power up the motors, the leds built into the blue esc still work and remain constantly on even though we cannot control the thrusters. This is leading me to believe that there might be an issue with the i2c lines that is causing the esc to not respond.
That was a mouthful so I will leave it at that for now. If anyone has any advice or sugestions for how I could potentially fix the blue esc’s, I would love to hear them.
