  "abstract": "Proposed is a neck device for absorbing shock and reducing vibration of a legged mobile robot. The device may include a shock absorber, a sensor platform coupled to a part of the shock absorber, and a variable dynamic vibration absorber mounted on the sensor platform. The shock absorber may be fixed to a body portion of the legged mobile robot and configured to absorb shock and vibration. The sensor platform may include a camera and an inertial measurement unit. The variable dynamic vibration absorber may be configured to adjust an absorption frequency of shock and vibration caused by a movement of the legged mobile robot. The shock absorber and the variable dynamic vibration absorber may reduce shock and vibration transmitted to the sensor platform, so as to reduce movement and rotation of the sensor platform.",
