Wheeled robots respond to music to create light ‘paintings’

Monday, February 9, 2026

People can collaborate with groups of wheeled robots to create art using an interactive system developed by researchers at Waterloo Engineering.

The robots trail coloured light as they move in response to a piece of music within a fixed area – which serves as the canvas – while a camera records them to produce a “painting,” or visual representation of its emotion.

“Basically, we programmed a swarm of robots to paint based on musical input,” said Dr. Gennaro Notomista, a professor of electrical and computer engineering. 

“The result is a cohesive system that not only processes musical input, but also co-ordinates multiple painting robots to create adaptive, expressive art that reflects the emotional essence of the music being played.”
