A Dancing Robot... Teaches Dancing.

Waltzing robot teaches beginners how to dance like a pro. An Daily news article, 24 May 2017, by Edd Gent.

The 1.8-metre-tall robot has wheels, but its upper body moves like that of a human dancer. A force sensor and two laser rangefinders track its student’s movements, which are compared against motion-capture data recorded from professional dancers to judge their performance.

As they progress, the robot gradually reduces the force used to lead them so they become less reliant on its guidance. Its face displays real-time feedback to help pinpoint mistakes, as well as showing them their overall progress to provide encouragement.
