Robotic Berimbau Plays Itself


If you have ever seen capoeira, you have undoubtedly heard the music of a berimbau. If you are not familiar, Capoeira is a Brazilian art form that melds martial arts, acrobatics, and music. This graceful fighting form is often accompanied by the sounds of a berimbau, a single-stringed musical instrument comprised of a gourd, a wooden bow, and a steel string.

[Ivan Monsão] and [Paulo Libonati] have constructed what is considered to be the first robotic berimbau in existence, capable of playing music without any human interaction. The robot strikes the berimbau’s metal string, mechanically muting the gourd when appropriate, and even shakes the caxixi (a rattle) in time with the music.

The builder claims that the berimbau learns songs by “listening” and repeating rather than having songs pre-programmed into the system. We can’t see any evidence of that functionality from the video, though we’d love to see the learning process in action.

While we try to find our VHS copy of “Only the Strong”, be sure to take a look at the following video of the berimbau playing itself.

  1. Building one of these has been perpetually 3rd on my list, as I rather like the sound of berimbau and it doesn’t have many degrees of motion.

    The caxixí in the video was a bit overpowering, though.

  2. I am surprised so many people don’t get this. 10 seconds spent on a Google search would show you what a berimbau is supposed to sound like.

    It doesn’t sound like Bach, moron – nor is it meant to sound like any westernized music you are used to. It’s a tribal african/brazilian fusion. Not everything needs to sound like the crap the record labels force down your throats.

    Awesome stuff!
