    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 method and apparatus for detecting a free fall of an electronic device. The method includes: sensing a falling acceleration of the electronic device using an acceleration sensor; determining whether the sensed falling acceleration is less than a predetermined threshold; when the sensed falling acceleration is less than the predetermined threshold, determining whether the falling acceleration is a statistical constant, which has a statistical significance, and is maintained for a predetermined time; and when the falling acceleration is a statistical constant and maintained for a predetermined time, determining that the electronic device falls freely. Accordingly, it is possible to exactly detect a free fall of an electronic device, irrespective of an error of the acceleration of gravity generated when a falling acceleration of the electronic device is measured, due to ambient conditions, e.g., a temperature change and a rotation acceleration generated when the electronic device rotates.
