A method of controlling the gait of a wearable robot using foot sensors of the robot. Whether or not the robot is walking is determined. When the robot is walking, whether the robot is supported on both feet or one foot using the foot sensors is determined. When the robot is walking and is supported on both feet, posture-maintaining control is carried out. When the robot is walking and is supported on one foot, support control is carried out over a supporting leg based on gravity compensation and load compensation. When the robot is walking and is supported on one foot, an imaginary repulsive force by which a swinging leg swings is generated.

Method of controlling gait of robot

The present invention relates to an IP based or network based audio packet switching system, and more specifically to an audio packet switching system for integrating each independent module into a single interface for consistent control and data flow. Independent modules, such as a RTP/RTCP, encoder/decoder and mixer, are interworked with reception and transmission buffers to make a system more flexible. Additionally, audio data paths inside the switch are controlled through an audio packet router. The multi protocol system employing the RTP provides a single RTP control interface for transmitting and receiving audio packets to completely manage the system totally and raises a degree of resource utilization of the system by making it easy to implement additional functions to the RTP and coder through the buffers.
