Controlling 2000 Servos !!!

Beau Schwabe

I figured that would get your attention ...

The only reason I am posting this is because I had some involvement many moons ago about designing a Servo Controller beast here in the forums that would handle 96 Servos, and even 144 servos.
For power management and other Sanity reasons (i.e. code timing) 96 Servos seems to be a more reasonable number.

I am not looking to sell these Servo 96 Controllers "YET", but I thought this would be interesting to some of us here in the forum that remember the discussion way back when.

So when a Client approaches you and wants to control and manage power for 2000 Servo's on an Art project he has... You bring him down to Earth (A little) and design a controller that can control 96 Servo's. Each of the Controllers can be daisy chained and programmed with a unique ID, so with 21 Controllers he can achieve a total of 2016 Servo's.

Here is a detail description of the Controller with Video and Example code:

This is how NMC (Network Modular Control) is. Been using it for motion control for many years.

The addressing is limited to 255 but easily expanded. FF is the broadcast address.

I use a 4-wire, multi-drop RS422 arrangement (master always has an open TX)
