In the multiRobot directory use the pleaseRun() and pleaseStop() methods to start and stop the robots. Where in pyro you would type self.whatever in this implementation you have to type watcher.brain.whatever or mover.brain.whatever to access properties of the Brain files.
In the PCA directory, use mode(behavior) to change the behavior of the mover. To run a robot use the run(bot) function and to stop one use stop(bot). To issue commands to both robots use the both(do) where do is stop, run. To access the brains, use wb and mb for the Watcher and Mover, respectively.
For some reason this file is missing from the XandY directory.
