World's First Running Humanoid Robot
Tokyo Japan, December 18th, 2003 -
Sony Corporation today announced the development of dramatically
enhanced motion of Sony's humanoid robot, enabling integrated
motion control for walking, jumping and running. By applying
this technology to QRIO, which is one of Sony's technology
platforms, Sony has successfully created the world's first*
running humanoid robot.
(* As of Dec. 18th, 2003, based on Sony's
investigation, as an autonomous robot with internalized
control system and power supply system)
Running humanoid robot experiment
In order to achieve stable motion control for conventional
humanoid robots, either one or both feet needed to be touching
the floor and, from the opposing force produced by the contact
with either of the feet, motion such as walking was controlled.
This is the control theory based on the so called ZMP (Zero
Moment Point) stable range and forms the foundation of robot
The new 'walking, jumping, running movement control' technology
which Sony has developed this time accomplishes motion involving
both feet losing contact with the floor at the same time,
which means it is a motion control technology enabling stable
running and jumping. The seamless addition of motion control
based on this new technology enabling running and jumping,
has lead to the development of a robot having outstanding
Furthermore, together with this new control technology,
in addition to powering-up and enhancing the output torque
of Sony's original and unique robot actuator, ISA (Intelligent
Servo Actuator), a new hardware unit suitable for the running
feature has been developed. By implementing this newly developed
ISA in QRIO and optimizing the new control system, Sony
has successfully created the world's first running feature
for a humanoid robot.
Sony will continue to utilize the QRIO platform for various
technological advances, leading to outstanding entertainment
robots highly suited to the co-existence with humans and
to the development of various technologies which can be
applied to other Sony products. In addition, QRIO is Sony
Group's Corporate Ambassador ;in fulfilling this role, QRIO
will take advantage of various opportunities around the
world to communicate Sony's vision of a world of dreams,
entertainment and curiosity as well as introducing the technology
that makes this vision a reality.
