    摘要: A walking control apparatus of a robot includes joint portions provided in each of a plurality of legs of the robot, a state database to store state data of each of the legs and state data of the joint portions corresponding to the state of each of the legs, when the robot walks, a position instruction unit to store desired positions corresponding to the state data of the joint portions, an inclination sensing unit to sense an inclination of an upper body of the robot, a torque calculator to calculate torques using the inclination of the upper body and the desired positions, and a servo controller to output the torques to the joint portions to control the walking of the robot. Since the robot walks by Finite State Machine (FSM) control and torque servo control, the rotation angles of the joint portions do not need to be accurately controlled. Thus, the robot walks with low servo gain and energy consumption is decreased. Since the robot walks with low servo gain, each of the joints has low rigidity and thus shock generated by collision with surroundings is decreased.

    摘要: Disclosed are a robot, in which a walking pattern of the robot is changed into a new walking pattern by stages when it is necessary to suddenly change the walking pattern to promote stabilization in walking, and a walking control apparatus and method thereof. When the walking pattern is changed, a preview time is decreased by stages and then is restored to its original state and thus it is possible to prevent the robot from losing its balance.

    摘要: Disclosed is a method of defining control angles to use a limit cycle in order to balance a biped walking robot on a three-dimensional space. In order to balance an FSM-based biped walking robot right and left on a three-dimensional space, limit cycle control angles to balance the robot according to states of the FSM-based robot are set on the three-dimensional space, and the limit cycle control angles on the three-dimensional space are controlled using a sinusoidal function to allow relations between the control angles and control angular velocities to form a stable closed loop within a limit cycle.

    摘要: Disclosed herein are an apparatus and method for controlling stable walking of a robot based on torque. In a method of enabling stable walking by controlling torque of a hip joint portion using a Finite State Machine (FSM) without solving a complicated dynamic equation, torque of a stance leg is finally calculated using pose control torque of an upper body, pose control torque of a swing leg, and initial pose control torque of a stance leg supporting the upper body. Accordingly, the robot may stably walk with torque balance. Since gravity compensation torque is applied, a torso of the robot is not inclined and the pose of the robot is stably maintained.
