摘要: Disclosed are a foot of a walking robot, which minimizes tilting of a sole of the foot and reduces a degree of freedom to easily control the walking of the robot, and a walking robot having the same. The foot includes a frame connected to a lower portion of a leg of the walking robot; and a plurality of impact absorbing plates having elasticity respectively connected to two sides of the frame such that the impact absorbing plates are separated from each other. Each of the impact absorbing plates includes a separation part connected to the frame and separated from a ground surface, a front ground part extended forward from the separation part and contacting the ground surface, and a rear ground part extended backward from the separation part and contacting the ground surface.

摘要: A method of controlling walking a biped robot to generate a walking pattern maximally similar to that of a human includes generating a walking pattern, calculating a walking pattern similarity corresponding to the walking pattern, and comparing the walking pattern similarity with a predetermined reference pattern similarity, and changing the walking pattern based on a result of the comparison. When the robot walks, a knee is maximally stretched and a horizontal movement of a waist is minimized such that the walking pattern of the robot is maximally similar to that of a human, thus enhancing an affinity for a human being and increasing energy efficiency.

摘要: Disclosed herein are a walking robot which controls balance using an ankle when the robot walks, and a method of controlling balance thereof. In a method of determining an angle of an ankle joint without solving a complicated dynamic equation such that the robot stays balanced so as not to fall, an angle of the ground is fixed as a reference angle for balance control of the robot such that the robot stably walks while maintaining the same balance control performance even when the ground is inclined. When the robot moves slowly or quickly, the robot may maintain balance. Since the robot stays balanced using the ankle of a stance leg even when the ground is inclined, the method is simple and is applied to a robot having joints with 6 degrees of freedom.

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.
