Major technology includes stable dynamic walking and running, full arm movement allowing throwing a ball, voice/face recognition, stereoscopic vision, obstacle avoidance, visual mapping, wireless network. Its "pinch detection" senses if a finger is caught in its joints - a major step to a robot tactile sense.


Dec 2003 - the QURO demonstrates the ability to run (meaning at some points in the walk, both feet are in the air). In other words, a robot that jumps! Note the new arm joints compared to earlier 2002 models. The QURO has some ability to recognize faces and objects in its environment. Here we seen one in a "playroom"

The robot uses the same OPEN-R architecture as Sony's four-legged autonomous Entertainment Robot "AIBO". Two technologies applying the OPEN-R architecture, the "actuator" that moves the joints and "Whole Body Coordinated Dynamic Control" for real-time control of the joints realize the biped walking motion of the SDR-4X.
To realize stable walking movement, the Zero Moment Point (ZMP) where the combined force of both the inertia and body weight meet, must be judged against whether balance is possible on the surface that is being walked upon.The SDR-3X uses two RISC processors for thinking and motion control. Information gathered from a CCD camera, microphone, posture sensors and touch sensors on the bottom of the feet are processed to synchronize movements of the body joints.
