Microcontroller selection

[DrTunk]

Hi All!

I'm about to take on a project to control several servos. And I am wondering what microcontroller set up I should use.
It'll start as a 3 by 3 array first, but ultimately needs to be a 10 by 10. I've used BASIC Stamp in other projects, but that will clearly not work for such a large array.

Also, I'd like to program in either C or Python preferably, but that's not crucial.

If anybody could point me in any direction I would greatly appreciate it!

Thanks in advance!

What do you mean by 'servo' specifically - describe it.

What do you mean by 3 by 3 array? Is this 9 servos? - ultimately 100?

Sorry for the vague description.

I'm looking to control a total of 100 servos. Anywhere in the range of 64 to 100 is fine. The plan is to start with a 3 by 3 array ( 9 servos total) and work out the kinks of the project. We will then apply it to the full scale of a 10 by 10 array. (100 servos total)

As far as the specific servos, that is still to be finalized. It seems that they will be hobby servos like the Parallax continuous rotation servo (link below), or something comparable.

Oh those servos..

So you'll need a bunch of PWM outs and I suppose a bunch of position inputs for feedback.

Since you seem a novice on this stuff it's hard to be real specific. Have you considered using Parallax's own Propeller processor? Twer me I'd look along that avenue. It can get you going faster because they've addressed running those servos using it. Heck! Look at the bottom of that link. They even list "Propeller Spin Code" for interface to those servos.
