Toyota Unveils Violin-Playing Robot

eldavojohn writes "Toyota has unveiled a robot that can play the violin. From the article: 'Toyota said it planned to further advance the robot's dexterity to enable it to use tools and assist with domestic duties and nursing and medical care. The robot has 17 joints in both of its hands and arms now.' It seems there have been small — or maybe even strange, impractical — advances in robotics repeatedly with demonstrations of robots performing a specialized task. Are we merely struggling to hard code each human activity as we strive for an all purpose android? Is there a chance artificial intelligence & robotics will ever become generalized enough to make interaction interesting?"

Obligatory Star Trek reference

Remember when Data played the violin for Spock's father in the episode of The Next Generation when he lost control of his emotions due to aging?

Re:Robot's sense of time..

Considering that I'm just wrapping up a semester of violin methods for a music ed degree, I find this achievement more impressive then building a robot to play any other instrument that I can think of because the violin requires extremely precise movements and pressure. The strings take a fair amount to force to depress, but the instrument itself is rather fragile. Also, to get an even sound out of it, the bow pressure has to constantly and smoothly changed while moving.

Force control?

I don't know anything about this particular robot, but methinx you wouldn't be able to do that with an open-loop sequence of scripted movements. There's definitely some sort of feedback going on. Some sort of force control, perhaps? And I wonder if there's some audio feedback as well to keep it in tune?

Self-awareness is great and all, but I don't think it's going to happen. Whereas there are many interesting challenges in lower-level control, and we do seem to get results there when we work at it.
