In your case it sounds like you have a chassis subsystem. The old way of handling that was to put all subsystems into the CommandBase class so all commands have easy access to subsystems. That's not a good design.

The 2013 approach is better. Put your subsystems into the Robot class and in your commands refer to Robot::chassis. If you use Robot Builder it follows this convention.

Since you are new to the command-based robot approach, you definitely should experiment with Robot Builder and carefully read the code it generates. It's quite good. Even if you decide not to use Robot Builder, you'll probably adopt a lot of what you learn from reading that code.

I do have a Chassis subsystem; I'll look into the 2013 documentation instead now. Thanks.
