It's a Sony biped
SONY Corporation announced the development of a prototype small biped entertainment robot "SDR-4X" that can adapt its performance to its environment and situations found in the home to further develop the possibility for a biped-walking robot. Richer communication with persons can be realised by a variety of sensor systems, performance control software based on memory and learning, and a flexible biped walking mechanism.
While improving the
output performance of small actuators that drive each joint, a newly
developed "Real-time Integrated Adaptive Control System"
controls a total of 38 joints in the robot's body in real time, based
on information from various sensors gathered in real time. More
advanced movements are realised by enabling biped walk on irregular
and tiled surface plus posture retention control under external
pressure. In addition, stable and flexible walk can be achieved by the
real time production of walking patterns such as pace and rotation
angle in accordance with various situations.
In addition to image recognition, sound recognition, and sound synthesis technologies, communication and movement control technology based on memory is incorporated in the SDR-4X to further enrich communications with people. The SDR-4X can recognise an individual person by detecting the front facial image captured by a color camera. The robot can also detect the direction of a sound source and recognizes an individual speaking by utilising 7 microphones located inside its head. By using embedded wireless LAN communication functions, the robot can synchronize data processing with an externally connected PC, which enables continuous speech recognition of many vocabularies.
Information on people and the location of an object obtained through image recognition technology is used as short and long term memory information. Based on this information, the SDR-4X can realise more complicated communication and movements. By inputting music and lyric data into the robot, it can produce a singing voice with vibratos and the composition of emotional, dynamic singing through voice synthesis can be realised to improve the robot's entertainment quality.
The SDR-4X will be shown at ROBODEX
2002, an exhibition of "Robots as Partners," from March 28 to
March 31 for 4 days at Pacifico Yokohama in the Yokohama Minatomirai
