You might remember my earlier posts regarding the reseting of Axon II with 18 servos connected. I have tried connecting up till four 6V batteries in parallel, but didn't work. Yesterday i connected two of the 6V batteries in series (hence 12V) and I am really surprised from the results. Axon does not reset anymore at all. In addition to that, my robot couldn't possibly stand up using the previous configuration but can easily now. I powered it for like 2 minutes or so. I was afraid the servos will fry or something. During the 2 minutes I checked how hot the servos were by touching them, and they appeared to be totally normal.
I am not really sure if this is the best way to do it but it fixed my problem, although i know that the servos operate at 6V or so. Is it okay to continue using it this way as long as the servos are not overheating ?
BTW, for the case where the Axon used to reset, i have measured the voltage using the oscilloscope (different intervals in ms,us,ns) while axon resetting. The voltage is not dropping suddenly and the minimum it goes to is 6.0V (usually around 6.5).
