Re: Mechanism behind trumpet playing robot?

Anyone know if it's an electronic oscillator with no air being passed

The University of Edinburgh made a set of artificial lips for experimenting with trombone design. It was two lengths of rubber tube with pressurised water in them. Increasing or decreasing the pressure changed the note. Air was blown through these lips to make the buzz

Someone got a PHd out of the project:

And here is her entire doctoral thesis:

You can see the apparatus in various pictures within it.

I wonder how big Mikey's doctoral thesis is? Can we read it online?

I have played trumpet once upon a time, but my ears did not get blue. I did almost pass out once however, as it took all oxygen from my head....

I waited until the end of the movie to see if it would take the trumpet down, so I could see the 'lips'. Unfortunately not. For the rest it is pretty good:-) And it likely does not spit so much as we do :-) Could add that as a feature though!

The apparatus shown in Fig. 6.9 (p 118) should have to be fitted into the robot head. The complexity of the artificial lips ("artifical mouth") with its mechanical constraints seem to indicate that the mouthpiece would have to be attached to it rather than to the trumpet body. I noticed only a small orifice in the robot's face where the mouth should be. Thus, the rumpet body should be only one side of a compressed air "Quick-Disconnect".

It downloaded readily for me in its entirety (except for the accompanying CD).
