I ran an example servo script that comes in Arduino Software to test the wrist servo and it works fine but when I use the NervoBoard to control the Wrist, it seems to not have enough power or maybe the impedance is not tuned correctly. I have the MRL Servo test sweeping from 0 to 180 and the wrist moves but just a tiny bit. Anyone experience this problem?
I figured it out. The MG 996R Servo was placed backwards and got hot and now theres a short across the motor inside the servo. Easy fix is to replace the motor.
How do you power your NervoBoard?
Do you have a voltmeter to check if you have the correct voltage coming to the servo?
I power the NervoBoard with a Power Supply that is at 6V Constant. I’m not sure what was the root cause but I was able to replace it with an HS485B with no problem.
Possibly your extracted potentiometer that is damaged or a bad soldering on the potentiometer wires.
