  • Patent number: 8369991
    Abstract: A system and method is disclosed for controlling a robot having at least two legs, the robot falling down from an upright posture and the robot located near a plurality of surrounding objects. A plurality of predicted fall directions of the robot are determined, where each predicted fall direction is associated with a foot placement strategy, such as taking a step, for avoiding the surrounding objects. The degree to which each predicted fall direction avoids the surrounding objects is determined. A best strategy is selected from the various foot placement strategies based on the degree to which the associated fall direction avoids the surrounding objects. The robot is controlled to implement this best strategy.

  • Patent number: 8352077
    Abstract: A system and method is disclosed for controlling a robot that is falling down from an upright posture. Inertia shaping is performed on the robot to avoid an object during the fall. A desired overall toppling angular velocity of the robot is determined. The direction of this velocity is based on the direction from the center of pressure of the robot to the object. A desired composite rigid body inertia of the robot is determined based on the desired overall toppling angular velocity. A desired joint velocity of the robot is determined based on the desired composite rigid body inertia. The desired joint velocity is also determined based on a composite rigid body inertia Jacobian of the robot. An actuator at a joint of the robot is then controlled to implement the desired joint velocity.

  • Patent number: 8332068
    Abstract: 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.

  • Patent number: 7756322
    Abstract: A mobile robot that is fitted with a camera and can be controlled from a remote terminal such as a mobile phone moves about in an event site to detect and track a moving object such as a visitor and entertainer. Because the camera along with the robot itself can change its position freely autonomously and/or according to a command from the mobile terminal, a desired frame layout can be accomplished by moving the position of the robot. Therefore, the operator is not required to execute a complex image trimming process or other adjustment of the obtained picture image so that a desired picture can be obtained quickly and without any difficulty. If the user is allowed access the managing server, the user can download the desired picture images and have them printed out at will. Also, because the selected picture images can be transmitted to the managing server, the robot is prevented from running out of memory for storing the picture images.
