I think getting rosserial working on the ARM side is as simple as running the rosserial_python ROS node. As such, there is no node creation for me to do on the ARM side. That said, I don't have access to a computer with ROS right now, so I can't observe this. It looks like some work will be necessary on the AVR side. rosserial acts as the main program for the AVR, and you create the C++ for the individual ROS nodes as functions in that program.

The only full rosserial micro-controller client is for Arduino, so we will need to port that to our AVR micro-controller. It looks like this is as simple as editing a header file and creating one class for low-level serial communication.

AVR side has been written but not yet tested. ARM side is indeed handled entirely by rosserial, so nothing needs to be done there.

Tested, fixed, seems to work :)
Also, there's now a launch file for ARM side, under scout_avr/launch.
