In a first, scientists have developed a marimba-playing robot that uses artificial intelligence to create its own music inspired by the works of musicians like Beethoven and Mozart. The robot with four arms and eight sticks writes and plays its own compositions on a marimba, using a database of well-known pop, classical and jazz artists. Researchers at Georgia Institute of Technology in the US fed the robot nearly 5,000 complete songs – from Beethoven to the Beatles to Lady Gaga to Miles Davis. They worked with the robot named'Shimon' for seven years, enabling it to listen to music played by humans and improvise over pre-composed chord progressions. Shimon is now a solo composer generating the melody and harmonic structure on its own, researchers said.

A team of artificial intelligence researchers from Northwestern University have built a robot on CogSketch model that will mimic the understanding level of common human beings. This computational model of analogy is based on the structure mapping theory of Northwestern psychology professor Dedre Gentner and the same artificial intelligence platform was previously developed in Forbus' Laboratory. According to Ken Forbus this model has the ability to understand the world as adult Americans do with an accuracy of 75 percentages. He further added that the things those are difficult for humans to understand are also difficult to recognise by these robots; best proof that it is mimicking human cognition. However; it can solve complex visual problems citing as one of the hallmarks of human intelligence.
