So you are terrible at dancing? Practicing with a professional dance teacher can improve your game over time. In the future, you may be able to use a robot to work on your dancing skills. At Tohoku University, a robot is already being used to teach dance. As you move with it, the robot’s joints exert force to guide you.
Just like a good dance teacher, this robot assesses your level as you move with it. The less experienced you are, the more the robot accommodates you. Advanced users get to lead though. The goal of this project was to allow researchers to learn how to make people more comfortable with robots.
