I have a robot that uses 4 mechanical arms. Each mechanical arm have 4 "READYTOSKY 30kg" servo motors on them. There is a moment that I need to use the absolute maximum force of only two mechanical arms (while the other two will stay still). Even though I do not change the coordinates of the other two mechanical arms (which I am not using) they consume voltage and "takes away" the full potential of force from the other two. Is there a way to stop the voltage consumed by the two other arms just for a brief moment using the Arduino code? shortly afterwards they will get back the voltage they need.

    delay(100);
    pwm.setPWM(1, 0, 380);

    pwm.setPWM(0, 0, 170);
