> Isn't it true that Aibo can't open it's mouth? So how could it fetch?
Most of the (popular) models of AIBOs have mouths that move (ERS-11x, ERS-210, ERS-7). Some don't (ERS-31x, ERS-220).
The moving mouth is mostly for the personality (having AIBO move mouth when talking)
The only one with intelligent software is the ERS-7. It will fetch/pickup its bone, and even do tricks with it. The bone is specially made and color coded.

Not the level of AIBO (which has a full blown voice recognizer built in software) or i-Cybie (which has a special chip just for voice recognition)
Something very simple could be added, but the CPU in the Pleo's head is underpowered and currently overworked.
(BUT if they open sourced the firmware, I suspect some people would try it)
Maybe something as simple as distinguishing a set of very distinct voice commands (like "GOOOD" and "NO" and "STAY THERE")

IMHO: I'd like to see Pleo do what it was originally promised to do (by UGOBE) before the original launch. Things like a smart personality that learns and explores its environment. This was never completed (search the web, there might be an old copy of their press release out there, circa Xmas 2007).
Features like true voice recognition or face recognition or picking up bones are not possible/practical with the current hardware, but smarter software is very possible, if someone would take the time to write it.
