Best way to Power an 8 servo - Quadbot
September 30, 2011
Hi. I want to power a Dagu Qadbot without sources, only batteries, but don't know the best way to Do it. It uses 8 micro servo - 8g, 4~6V, and draw a current that I don't know the specific value as I didn't find a Datasheet.
So, as I'm almost sure that only Arduino will not be able to power the 8 servos, I'm thinking about 2 solutions:
1st - Use 4AA Battery to power - the Arduino i parallel with the servos. This way I'd power the servos directly and just connect the digital pin to the arduino.
Problems: Reading some posts, I've seen people reporting that arduino resets. A possible solution would be the one described on this topic, which I didn't understand fully : http://letsmakerobots.com/node/7722
2nd - Use a 9V battery to power arduino, and 4AA battery to power the servos. This way I think I'd have no problems, but this solution is more expensive and heavier.
Please give your opinions,
