    摘要: A method of controlling a biped walking robot to balance the robot based on a sensed ground reaction force. In the method, X and Y coordinates are assigned to positions of sensors attached to a sole of a leg of the robot and a corresponding Z coordinate is assigned for at least three of the sensors based on the sensed ground reaction force sensed by at the sensors, respectively. A ground reaction force plane is specified based on the sensed ground reaction force and a normal vector perpendicular to the ground reaction force plane is calculated. A roll angle about an X-axis and a pitch angle about a Y-axis are calculated and an actuator is driven in correspondence to the roll angle and the pitch angle to move a part of the robot to align the normal vector with a reference vector of the gravity direction.

    摘要: There are provided an autonomous vehicle, and an apparatus and method for estimating the motion of the autonomous vehicle and detecting three-dimensional (3D) information of an object appearing in front of the moving autonomous vehicle. The autonomous vehicle measures its orientation using an acceleration sensor and a magnetic flux sensor, and extracts epipolar geometry information using the measured orientation information. Since the corresponding points between images required for extracting the epipolar geometry information can be reduced to two, it is possible to more easily and correctly obtain motion information of the autonomous vehicle and 3D information of an object in front of the autonomous vehicle.

    摘要: A landmark used to effectively determine the location of an autonomous vehicle, and a self-localization apparatus and method using the landmark are provided. In the self-localization method, first, first and second outer line information and shape information are extracted from a landmark image received from a camera. Next, a projective invariant is calculated from the shape information and stored in a hash table. Thereafter, the calculated projective invariant is compared with reference projective invariants for a plurality of landmarks stored in a predetermined data storage area in the form of a hash table, thereby determining which landmark corresponds to the landmark image. Then, information on the distance and orientation of the determined landmark with respect to the autonomous vehicle is analyzed in response to the first and second outer line information.

    摘要: Provided is a foot structure for a humanoid robot capable of effectively keeping its balance in a pause state or action. The foot structure includes a support; a plurality of lower structures having an upper member connected to a bottom of the support; a plurality of lower members having a plurality of independent portions each movably connected to the upper member; and a revolute joint for coupling the upper member and the lower member. Since a contact between the foot structure and the floor is smoothly made, a shock is prevented from being transferred to a body of the humanoid robot. Also, a vibration generated when the humanoid robot steps on the floor is eliminated, so that the humanoid robot can pose a stable and smooth gate.
