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)

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 motion control.

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 motion capabilities.

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.
