Fredrik Gran is a composer from Sweden who built a two-armed robot that can play bowed instruments such as the cello and the double bass.
Just like a human, one arm of Gran’s robot draws the bow across the instrument and one hand is in charge of the fretting.
The video above shows Gran’s invention in action. Take a look! We think you’ll be impressed!
