Has anyone used the Pololu maestro servo controller with their ez board? I have 25 servos and 3 stepper motors sitting on my desk waiting to be used. I was going to power the servos and steppers separately from my ez board when I came across the maestro controller while looking for stepper controllers. I'm new to robots but planed a class research project based on robots to learn about them. I wanted to use the digital I/O (ez board) to control the maestro controller but am unsure as to how I would do this. Or I2C maybe, usb possibly? The maestro can be daisy chained together and I was hoping to then connect to the ez board and then to the computer via its wireless contention.
My overall goal is to create a robot that can complete complex movements, or basically dance. I really hope to use the maestro because space and weight are a factor. Using maestro controllers the ez board can be mounted in the base, instead of on the robot making the programed movements, saving lots of weight and wires running everywhere.
I'm a design student and building it is not a problem and in fact I have most of the parts with the rest ordered. I choose the ez board because of the simplicity in getting started, however, I realized I would not need to add an adruino board if I moved some servos/steppers off of the ez board (no brown outs). At first this was a great idea, then I realized I took the simplicity of the ez board and complicated it some what. Any help would be appreciated.
Upgrade to ARC Pro
Your robot can be more than a simple automated machine with the power of ARC Pro!
The easiest way to get more servo's connected to ARC is to purchase a second EZ-B board. You can connect multiple boards in the software. I believe makershed still has them in stock. If you're willing to wait, you can also purchase the EZ-Mini board. It'll be a lot lighter and smaller than the current EZ-B.
For controlling stepper motors using the EZ-B, this is a good tutorial to look at.
My omnibot is full of 1 to 2 foot extension wires. Have never had any problems with them.
I have read that the ping sensor can be a bit sensitive to what is used to connect it up but even then I have had no problem with mine on a 2 x 12" extensions (one cut and soldered to the sensor).
