This is not going to be the easiest place to start hacking Pyro because
you are on two different sides: the pysim is a server, and the robot and
brain are over on the client side.
You would need a way to set a state property in the server. To test this
idea out, you could reach into the simulator from outside, and set a
robot's state property. For example, you could do something like:
robot.simulation[0].eval("self.robots[0].state = 'red'")
To do this in a more proper way, you'd probably want to create a method on
the client, like:
robot.setState('red')
That would take a method of encoding the arguments, and then decoding them
on the server side. This code is a major hack right now, where messages
get turned into a string (like "s_red") and then decoded in pysim.py.
As an aside, "self" in the Pyro Command window is the brain object.
