JHU's Bionic Arm

Quote from previous post:
"Next thing we know, the robot can play fantasie impromptu."

I've totally forgotten about an article(PopSci) on a bionic arm that I came across a couple weeks ago. Really cool, the thing has 25 joints, (FTA) nimble enough to play the piano. A normal arm has 30 joint motions, this is only short of 5 more, double yay! Proto 2, as it is called, was developed by Johns Hopkins University Applied Physics Lab. It uses myoelectric sensors to move the arm. From what I gather, myoelectric signals are are electrical signals that allow us humans to control our muscles. (n00b here, correct me if I'm wrong.)

Getting this 25 joints onto a robot and controlling them probably wouldn't be much of a big problem, afterall the robot doesn't need to worry whether the arm will be able to synchronize with its muscles, since it has none to begin with. Now that there's the mechanics available, it's only a matter of time before somebody writes the software needed for a robot equipped with this arms mechanics to pay fantasie impromptu. Ouch! I think I'll go and practise my piano when I'm done with this post.

My heart skips a beat everytime I read/hear about advances in bionics and robotics. I don't know, these things totally captivate me.

These are the other websites I read from:

Toyota's Violin Robot

Toyota researchers just unveiled their violin robot to the press. Very, very impressive. No, let me rephrase that. It's DAMN COOL!!! Here: http://www.reuters.com/news/video?videoId=72177

FTA, the robot has 17 joints in both of its hands and arms. Very dexterious bunch of fingers that thing has. I can't think of any specific everyday-task that will put that skill to use for now, folding paper cranes, perhaps? The people from the medicine field might want it for operations, which requires precision and steady hands. What I can think of, is that the mechanics used here would be another step closer to Ghost In The Shell-like prosthetics.

I'm feeling pretty noobish now. I've spent 4 years learning the violin, and I don't think my playing sounds as accurate as the robot... The things even does vibrato, which I'm still struggling to master. I didn't see the robo's wrist move, but there was vibrato anyway.

Next thing we know, the robot can play fantasie impromptu. You know, all those passages with running notes. Aww man, I've spent like, the last couple years trying to play the first section, and it's still no good.

I think the robots will surpass me at playing violin/piano soon. *sigh*

First Post

Ahahhaha, first post.

Just moved from Friendster, since their blog is friggin' slow. Lot's of free time to ramble now, since SPM just ended yesterday. ICT subject was on the very last day of the exam season. Wonderful.

After teh paper, went to Metro Prima to watch Enchanted. Walk, walk, walk. Next day (Friday), went to PC fair. Walk, walk, walk.
