Good day all,
I’ve been building the RBX1 for a small work project to test the arm and it’s been working fine to date. I’m looking especially at motors 3, the forearm motor.
First of all, I’ve been using the example/robot.py with the current values
joints.setCurrent(75, 75, 75, 75) # Doesn’t run. Does tick and tries to move, but doesn’t work.
I couldn’t find a reference to the unit of current. mA? A?
I tried to increase the current because I though it would help it with no success.
The default values in the code should be self.setCurrent(70, 90, 100, 100) so I tried this as well.
However, in a clean state python3 shell, doing a getParam(KVAL_HOLD) and other parameters returns 41 at all time. I’m not sure where the 41 comes from.
I guess I’m trying to figure out how should I tune my current and is it normal that my motor is stopping at higher current? The smaller wrist and wrist rotation motors tend to run quite hot as well so I’d like to fix this. I already melted through one of my parts with the geared motor when I increased the current…
