Robots are going to do many things for us, including helping solo musicians put on a better show. Take the Cabot for instance: it is a percussion robot that attaches to a cajon and can be activated from a smartphone. It has 3 arms to work the cajon. Its rhythms blend with most musical instruments.
You can use your smartphone to create your own rhythms and sync with your other devices. Like what you see? You can find out more about this project here.
