China’s dancing robots: how worried should we be?

Eye-catching martial arts performance at China gala had viewers and experts wondering what else humanoids can do

Dancing humanoid robots took centre stage on Monday during the annual China Media Group’s Spring Festival Gala, China’s most-watched official television broadcast. They lunged and backflipped (landing on their knees), they spun around and jumped. Not one fell over.

The display was impressive, but prompted some to wonder: if robots can now dance and perform martial arts, what else can they do?

The insect-inspired bionic eye that sees, smells and guides robots

The compound eyes of the humble fruit fly are a marvel of nature. They are wide-angle and can process visual information several times faster than the human eye. Inspired by this biological masterpiece, researchers at the Chinese Academy of Sciences have developed an insect-scale compound eye that can both see and smell, potentially improving how drones and robots navigate complex environments and avoid obstacles.

Robot swarms turn music into moving light paintings

A system developed by researchers at the University of Waterloo lets people collaborate with groups of robots to create works of art inspired by music. The new technology features multiple wheeled robots about the size of soccer balls that trail colored light as they move within a fixed area on the floor in response to key features of music including tempo and chord progression. A camera records the coordinated light trails as they snake within that area, which serves as the canvas for the creation of a “painting,” or visual representation of the emotional content of a particular piece of music.
