There's one problem with this story: the author doesn't give any evidence that this is a real robot. A robot, by definition, can perform tasks autonomously. This machine was probably programmed to go out on stage and start blowing into the trumpet. Likewise, it doesn't "play" the trumpet. It merely pushes air into the trumpet according to what the code tells it to do. The day that Toyota designs a machine that hits a wrong note is the day that it built a real robot.
