One build team finished their ROV. The ROV works for 5-8 minutes and then cuts out completely. The power indicator light on the controller has a faint glow...which is not anywhere near the glow it starts with initially. The topside ethernet indicates it has lost contact with the ROV.
We found one very small nick in a wire by the motor. This nick was epoxied. Unfortunately, the ROV still cuts out. We have checked the wires for signs of wear, none were found. We have done a continuity test for the wires that connect to the control board. We did not find any bad connection. We are not seeing water leakage in the battery compartments or electronics compartment.
Do you have any other ideas to check? None of our build team have much experience with electronics. We have learned much through this project though, and are anxious to get the ROV fully functional.
