Watch: Flying robot pop stars to perform US gig
Robotics experts in the US have created a pop group of flying drones.
The drones are pre-programmed to play a variety of different songs and instruments completely on their own.
The band don't have a name yet, but they are due to play in front of a live audience in Washington DC before heading off on a mini tour in America.
Daniel Mellinger, one of the team who made the robotic music stars, explains how the band was formed.
