Raspberry PI and Roboclaw Motor Controllers

Hello all.  I apologize up front if this question is too simple or obvious.  I am new to the forum and robotics.

I am trying to build a tracked rover that I would like to control with a Raspberry PI via Amateur radio (13cm AREDN).  I have purchased two planetary motors (313 rpms) and a Roboclaw 2X15 motor controller.  My plan is to connect the motor controller to thePI's GPIO ports and control the rover via VNC over-the-air.

What I can't find or figure out is how to control the controller via the PI.  I was thinking there would be a simple stock / available Linux program to use the arrow keys to drive the motors.  Unfortunately I have not found anything - perhaps I am look for the wrong thing.

My question to the forum is - Has anyone used a Roboclaw controller with a Raspberry PI or have any idea how I can do this?

Thanks in advance for your assistance.

Hello Hank!

Which router are you planning on using on the tracked vehicle?  One of the Ubiquity "Bullets?"

And why AREDN?  Just to extend the range?  I think I might opt for an Arduino using a nRF24L01P+PA+LNA both for the tracked vehicle and another Arduino nRF24 pair along with a joystick for the controller, but that's just me.  I had thought of using AREDN as well, but power requirements would be much higher have to run a router as well.

I am using a 2g Ubiquiti Bullet.  I am doing this for range and dedicated spectrum.  My place in WV has MESH coverage all over the property.  The PI will also support peripherals, such as camera and external relays for lights and such.

Well if the mesh network already exists then that is probably the best way to go.  How large is the property you need to cover?

Do keep us posted though.
