That's good to know.
But, to be clear, ARIA is not a P2OS replacement. Rather (at least as I
understand it), P2OS is being replaced by AROS, which is *not* Open
Source. P2OS and AROS are embedded OSs that run on the robot's
microcontroller and do things like low-level motor control and sonar
ARIA, on the other hand, is more like a Saphira replacement, or at least
alternative. It runs on the host computer (e.g., PC104, laptop) and talks
to the robot's microcontroller over an RS232 line. So Saphira, Ayllu,
Player, and ARIA are mutually exclusive choices that the user has for
writing programs that control ActivMedia robots. Player and ARIA are Open
Source; Saphira and Ayllu are not.
