It's a framework. * it's a loosely coupled messaging framework (so you can have 5 daemons that talk to each other to accomplish control at multiple levels) * it's got robotics libraries with difficult robotics algorithms (PID tuning, forward and reverse kinematics, a way to run control loops very fast, ...) * it's got sensor libraries (algorithms) and drivers * it's got a simulator * it's a linux distro specialized for robotics You can keep going for a while with this.
