Dancing Humanoids
Dance motion analysis and dancing humanoids for preservation of
Japanese traditional dances
Human & Robotics Motion Group
There are a lot of traditional dances in Japan. Some of them are being disappeared for lack of dancers. We are trying to preserve these dances and represent them with a humanoid robot. To achieve useful preservation, we analyzed raw motion data acquired from the motion capturing system, then the ‘Motion Primitives’ that are basis of whole dance motion sequences are detected.
We also aim to realize a dancing humanoid robot for representation. The first problem is the balance control. If we use the data just acquired from human motions, the robot must fall down because the size, weight or other property of the body portions are completely different. At first, we modify human motions to fit the robot’s mass composition, joint structure and dynamic capacities. However, the resulting shapes of the dance motion are still different. To resolve this problem, we are trying to make robot’s motions to resemble the human’s ones under the restriction of the robot’s characteristics and availability.
