1  Using Arduino / Motors, Mechanics, and Power / Re: How to move 18 Servos siumltaneously on: November 17, 2012, 12:36:09 am
Is there anyway to go about knowing how much current I would actually need for 18 of them?

Besides I'm probably planning on powering it using a wall power socket instead of an independent battery pack as I presume it would draw so much power so much so that depletion of the battery pack would be way too fast

I'm probably using a continuous servo motor of this scale,

there isn't an indication on how much power it is gonna use but I've read through most places and they recommend having 1A per servo to power it up sufficiently.

And considering the amount of power needed, what kind of power adapter would you recommend? I have been googling for suitable power adapter but there doesnt seem one spec at 18A or higher

Yes I have notice there's a price difference between a Arduino mega board and a standalone servo controller. Am I right to say that the Pololu Servo controller do not need to be connected to any other external devices for it to function? Just having a power source of approximately 18A+ would suffice? In addition, is the servo controlled through the arduino software as well? Sorry lots of noob-ish question as I do not deal with servos and servo control all that much...

Am I right to assume that with the use of the Arduino Mega, I will be able to individually control the speed of each of these 18 servo motors? I was under the impression that they can only be done through the use of the PWM PINS. (Arduino Mega has 14 PWM pins)

Hi I am in need of some advice before I do any purchase of the required parts to do construct my device. I need to connect 18 servo motors to my arduino board and I do not have a good idea how I should go about doing it.

Since I'm moving 18 servos at the same time, I assume the power required would be pretty immense.

Wall power Adapter connected to >> Arduino UNO connected to >> Servo controller connecter to 18 x Servo motors

Problems encountered:

1. Is this the right setup I should have?
2. What kind of wall power adapter should I be looking at? (like power and current etc)
3. How do I control individual servos using the Servo controller and how should I connect a servo controller to the Arduino board
4. Would servo controller like this be effective in doing what I need to do? http://www.pololu.com/catalog/product/1356

Thanks for any advice
