<P>PROBLEM TO BE SOLVED: To provide a visual perception system and method for a humanoid robot. <P>SOLUTION: A robotic system is equipped with: a humanoid robot; and a distributed controller for controlling the movement of each of robotic joints. The controller includes a visual perception module (VPM) for visually identifying and tracking an object in the field of view of the robot under threshold lighting conditions. The VPM includes: optical devices for collecting an image of the object; a positional extraction device; and a host machine having an algorithm for processing the image and positional information. The algorithm visually identifies and tracks the object, and automatically adapts an exposure time of the optical devices to prevent the feature data loss of the image under the threshold lighting conditions. A method of identifying and tracking the object includes steps of: collecting the image; extracting positional information of the object; and automatically adapting the exposure time to thereby prevent the feature data loss of the image. <P>COPYRIGHT: (C)2011,JPO&INPIT
