DEVICE FOR ABSORBING LANDING SHOCK FOR LEGGED WALKING ROBOT

摘要

The present invention relates to a sound absorbing device for a legged walking robot. The sound absorbing device for a legged walking robot according to the present invention, which has first and second joint links for forming the joints of a legged walking robot, comprises: a sound absorbing body which has an inner space; a first link part of which one end is coupled to the sound absorbing body and the other end is rotationally coupled to the first joint link; a second link part of which one end is located inside the sound absorbing body and the other end protrudes from the outside of the sound absorbing body and is rotationally coupled to the second joint link; a first elastic part which is located inside the sound absorbing body, has both ends elastically supported on the facing surfaces of the first and second link parts, and is installed while being compressed with a preset pressure; and a second elastic part which is installed to be elastically compressed according to the longitudinal movement of the second link part. Thereby, the sound absorbing device for a legged walking robot can prevent mechanical damage and accurately contrive the track of the legs of the legged walking robot since shock absorption does not occur even when a shock caused by walking is transferred.
