  • Patent number: 9221507
    Abstract: 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.

  • Patent number: 9054614
    Abstract: An apparatus and method to control a brushless direct current (BLDC) motor, which accurately detect driving current. To this end, the BLDC motor control apparatus includes a BLDC motor, a driver to generate driving current to drive the BLDC motor, a current measurer to measure the driving current, a pulse width modulator to change a driving voltage to drive the BLDC motor; and a controller to control the BLDC motor. The controller detects the amount of the driving current in synchronization with pulse width modulation of the pulse width modulator and determines current with a minimum change due to a variation of counter electromotive force, among currents flowing through a plurality of coils, as the driving current, thereby accurately detecting the driving current.

  • Patent number: 8892257
    Abstract: Disclosed is a method of absorbing an impact generated when a foot of a walking robot lands on the ground to perform the walking of the walking robot. When the foot of the walking robot lands on the ground, an F/T sensor installed on the sole or the ankle of the foot measures external force and the posture of the sole of the foot is adjusted in a direction of complying with the external force, and thus an impact transmitted to the walking robot in landing is absorbed. Further, the posture adjusting speed of the sole of the foot is adjusted according to walking speeds (stopped, walking, running).
