We've seen robot drummers before - and we all know you don't need two arms to be a great percussionist.
But we haven't seen anything quite like this.
New Scientist has a great story about Jason Barnes, a human drummer with a robot arm who will use his unique physicality to make new types of beats onstage.
With the help of engineers at the Georgia Institute of Technology, he's developed a robot arm which can let him play as well - or arguably better - than any other drummer in the world.
Head over to New Scientist for the story, and check Barnes out in action above.
