  • Publication number: 20090321150
    Abstract: Disclosed are a walking robot and a method of controlling the same, in which one method is selected from a ZMP control method and a FSM control method. Based on characteristics of a motion to be performed, the current control mode of the walking robot is converted into a different control mode, and the motion is performed based on the converted control mode, to enhance the efficiency and performance of the walking robot. The method includes receiving an instruction to perform a motion; selecting any one mode, which is determined to be more proper to perform the instructed motion, out of a position-based first control mode and a torque-based second control mode; and performing the instructed motion according to the selected control mode.
