We are building a robotic arm that requires the use of 6 servos. I'm planning to use one external power source to power all the servos. The problem is that each servo has a different current draw rating. Some servos draw up to 10A when stalled (which should not happen). In the same time, we are using small servos, which draw 2A of current if stalled. However, they all have the same voltage rating (~6V).
So, I was wondering how they can all be powered using only one power source?
Here are more details:
- Total stall current: ~30A
- Total required power: ~170W
