A piano is as much a robot as a vacuum cleaner is. It's a tool you can use, nothing more.
A player-piano is indeed a primitive robot. You are right about that. Ever heard of conlon Nancarrow? One of the more interesting American composers who made music for player piano all his life. Here's a link to one of his pieces: http://www.youtube.com/watch?v=UPdX85cv_D8 But one of the disadvantages is that because of the way it's built, a player piano can't do dynamics. You can only play louder if you play more notes at the same time.
Yamaha Disklavier and such CAN be used as robots. They're machines on their own, but if you feed them real time information by using a computer with sensors and a custom made program they can indeed react to their environment. About sounding mechanical, that's an illusion. When making a piano robot, there are only two parameters that count: the the timing and the pressure you use to push down a key. compared to windblowers, this is very simple, because you won't have to modify the sound a string after it has been beaten. If a Disklavier sounds mechanical, it is because of the way the piece of music is programmed, not because of the limitations of the instrument itself. If you want it to play some music you can either program it to play exactly what it says on the score, or build in some errors, like a human player would make. Slight deviations in timing and velocity. The first way would make the music a bit mechanically. The second way can sound perfectly realistic, if you do it right. But then you have to ask yourself what the point of making robots is, if you're asking them to make the same mistakes as humans do.
Now that robot clarinet is an interesting experiment. But not finished at all. It is interesting because it shows that much more research is needed in this area. It is very impressing to do a crude version of 'flight of the bumble bee' but it only shows that the fingering mechanism is working ok. Now that part is quite comparable with a technology used by a disklavier. Not that new at all, you just need smaller electromagnets. The real challenge lies with the mouthpiece, and they're not there yet. For now, the instrument plays everything at the same volume, and I have reason to believe it won't be able to make breaks between two notes. There's certainly no articulation at all, and just that is what makes a clarinet sound real. So it's a good project, but they haven't figured it all out, just as the people who are doing this project have not figured it all out.
The "figuring out" part is a challenge for every instrument you're trying to turn into a robot. And the video you watched is the result of an earlier experiment, where they tried to emulate an electrical guitar. If read a bit further, you'll see that they're working on wind- and string instruments AND on the interaction with human players. That's still a bit more complicated than the examples you gave.
Of course they're not the first trying to make a musical robot. One of them studied in Belgium for a year (also mentioned in the article) at Logos foundation. Here's their website, it has a small introduction video on the right: http://www.logosfoundation.org/mnm/index.html. And here's a recent video of their current robot orchestra improvising with two human performers: http://vimeo.com/11487694
What you will notice is that this orchestra doesn't have a string instrument. Simply because it's very complicated to make one. So what these people are trying to do is quite new indeed.
About the poor pitch and intonation you mentioned: you shouldn't think that western tuning is the only one that's right. It just sounds more right to you because that's what you've listened to your whole life. That's why you think music sounds out of tune when it doesn't follow this tuning system. But it's really dependant on the culture you grew up in. Or perhaps you're convinced a Chinese gamelan orchestra plays 'out of tune' because the players just like to terrorize their own ears?
