A robotic system includes a humanoid robot with robotic joints each moveable using an actuator(s), and a distributed controller for controlling the movement of each of the 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 feature data loss of the image under the threshold lighting conditions. A method of identifying and tracking the object includes collecting the image, extracting positional information of the object, and automatically adapting the exposure time to thereby prevent feature data loss of the image.

A robot apparatus which, by exploiting limited resources highly efficiently, is capable of making expressions matched to the motion or to complex variegated feeling or instinct states, representing the crucial information in achieving smooth communication with the human being, is disclosed. A method of expression by the robot apparatus is also disclosed. The robot apparatus expresses plural states, such as emotional states or the processing states of perceptual recognition, by a light radiating device loaded at a location of the head part of the humanoid robot apparatus walking on two legs.

A momentum-based balance controller controls a humanoid robot to maintain balance. The balance controller derives desired rates of change of linear and angular momentum from desired motion of the robot. The balance controller then determines desired center of pressure (CoP) and desired ground reaction force (GRF) to achieve the desired rates of change of linear and angular momentum. The balance controller determines admissible CoP, GRF, and rates of change of linear and angular momentum that are optimally close to the desired value while still allowing the robot to maintain balance. The balance controller controls the robot to maintain balance based on a human motion model such that the robot's motions are human-like. Beneficially, the robot can maintain balance even when subjected to external perturbations, or when it encounters non-level and/or non-stationary ground.

A system and method is disclosed for controlling a robot having at least two legs that is falling down from an upright posture. An allowable stepping zone where the robot is able to step while falling is determined. The allowable stepping zone may be determined based on leg Jacobians of the robot and maximum joint velocities of the robot. A stepping location within the allowable stepping zone for avoiding an object is determined. The determined stepping location maximizes an avoidance angle comprising an angle formed by the object to be avoided, a center of pressure of the robot upon stepping to the stepping location, and a reference point of the robot upon stepping to the stepping location. The reference point, which may be a capture point of the robot, indicates the direction of fall of the robot. The robot is controlled to take a step toward the stepping location.

A control system for a bipedal humanoid robot that utilizes certain fundamental characteristics of bipedal motion to provide a robust and relatively simple balancing and walking mechanism. The system primarily utilizes the concept of “capturability,” which is defined as the ability of the robot to come to a stop without falling by taking N or fewer steps. This ability is considered crucial to legged locomotion and is a useful, yet not overly restrictive criterion for stability. In the preferred embodiment, the bipedal robot is maintained in a 1-step capturable state. This means that future step-locating and driving decisions are made so that the robot may always be brought to a balanced halt with the taking of one step. Other embodiments maintain the bipedal robot in an N-step capturable state, in which the robot may always brought to a balanced halt by taking N or fewer steps.

A robot using less storage and computational resources to embody panoramic attention. The robot includes a panoramic attention module with multiple levels that are hierarchically structured to process different levels of information. The top-level of the panoramic attention module receives information about entities detected from the environment of the robot and maps the entities to a panoramic map maintained by the robot. By mapping and storing high-level entity information instead of low-level sensory information in the panoramic map, the amount of storage and computation resources for panoramic attention can be reduced significantly. Further, the mapping and storing of high-level entity information in the panoramic map also facilitates consistent and logical processing of different conceptual levels of information.

The present invention provides an animation creation program whereby the posture of a structure comprising a plurality of links can be determined by means of a simpler and easer operation. In accordance with the movement of one link in the structure comprising a plurality of links, the animation creation program of the present invention automatically determines the spatial positions of the other links of the structure so that the structure retains a posture that is as natural as possible.

A system, method, and computer program product for generating dynamically feasible whole-body motion of a humanoid robot while realizing specified upper-body task motion are described. A kinematically feasible upper-body motion is generated based on the specified upper-body motion. A series of zero-moment points (ZMP) are computed for the generated motion and used to determine whether such motion is dynamically feasible. If the motion is not dynamically feasible, then the torso acceleration is modified to make the motion dynamically feasible, and otherwise synchronized as needed. A series of modified ZMP is determined based on the modified torso acceleration and used to distribute the resultant net ground reaction force and moment to the two feet.

[Solution] A pneumatic air muscle has a cylinder (112) provided in a flexible member (100) forming a pneumatic artificial muscle. At the center of an upper lid element (109) of the cylinder, a through hole is opened, and an inner wire (103) of a Bowden cable passes through this through hole and is coupled by means of a spring (106) to a bottom portion of the cylinder. When the pneumatic artificial muscle contracts, the inner wire (103) and the pneumatic air muscle move together because of the stopper (105), and the contraction force is transmitted. In contrast, when the pneumatic air muscle extends, the stopper (105) is disengaged, while the tension of inner wire (103) is kept by the spring (106) to prevent slacking.
