Calligraphy robot uses a Motion Copy
System to reproduce detailed brushwork
Japanese researchers have found way to preserve the centuries old
tradition of calligraphy. They have created a robot that memorize artist’s
brush strokes and recreates art and calligraphy.
A research group at Keio University, led
by Seiichiro Katsura, has developed the Motion Copy System. This system can
identify and store detailed brush strokes, based on information about movement
in calligraphy. This enables a robot to faithfully reproduce the detailed brush
strokes.
The robot needs to be taught before it can
create something. The artist starts drawing calligraphy while his brush is
attached to the robot’s mechanical hand. It remembers each move the artist
makes, the pressure on the brush and the angles and then just copies them,
Agence France Presse reports.
This system stores calligraphy movements
by using a brush where the handle and tip are separate. The two parts are
connected, with the head as the master system and the tip as the slave system.
Characters can be written by handling the device in the same way as an ordinary
brush.
“The device is endowed with a motor that moves as the person moves the
brush. And then the moves are recorded digitally. Then the robot uses the same
motor to produce the exact same moves,” Associate Professor Seichiro Katsura of
Keio University explains.
The aim of the robot is to preserve the
traditional Japanese calligraphy and can also be used to recreate other pieces
of art.
Unlike conventional motion capture
systems, a feature of this one is, it can record and reproduce the force
applied to the brush as well as the sensation when you touch something. Until
now, passing on traditional skills has depended on intuition and experience.
It’s hoped that this new system will enable skills to be learned more
efficiently.
