Music and dancing are activities best
known human entertainment, and are
linked to the ability to socialize. The
sound and movement patterns
characterize the dance.
Robots That Learn to Dance from Observation
This
Recent generations of humanoid robots
increasingly resemble humans
This progress
Has led researchers to design robots that can mimic
dancers complexity and style of dance choreography
human.
It allows
the robot what to do and how to do it from
observation. The model is divided into two legs.
At the end they concatenate the two and dynamic
filters are applied to prevent the robot hit with it.
for this
Researchers at the University of Tokyo have developed
the learning-from-observation (LFO) training method
Generating upper-body motion
use the same task-model strategy as for leg
motions. In this case, each model represents
a key pose of the imitated dance.
Generating whole-body motion
To generate executable motion, we use a dynamic filter and
conduct skill refinement. The dynamic filter compensates the
zero-moment point and the yaw-axis moment
Motion from Sound: Intermodal Neural Network Mapping
Robots that interact with humans must be
able to react to multimodal sensory input.
Intermodality mapping
consists of
two phases. First, in the learning phase, the robot
observes some events together with associated sounds.
The robot memorizes these sounds along with the
motions of the sound source
Keepon
uses signal processing techniques
and accelerometers to detect
movements of the person
Dance Partner
It uses a database of
knowledge and estimates
to predict the movement
Control system architecture
uses
Step transitions that is, when and how the human partner
changes steps in a dance sequence are important for the
robot to generate its own dancing motion
