Legged Robot Neck Vibration Absorber for Stable Sensor Platforms

The patent applies the dynamics principle by making the vibration absorber's characteristics adjustable rather than fixed. The stiffness and damping coefficients are made variable through controllable elements (such as adjustable springs and dampers), allowing the system to adapt its absorption frequency to match different walking patterns. This transforms a static vibration absorber into a dynamic one that can be tuned in real-time.

The patent implements parameter changes by modifying the physical parameters of the vibration absorber (stiffness, damping coefficient, mass distribution) to adjust the absorption frequency. These parameters can be changed based on the detected walking pattern, enabling the same device to effectively absorb vibrations across multiple operating conditions without requiring multiple fixed-frequency absorbers.

The patent employs relatively simple and cost-effective vibration absorption components (such as basic springs, dampers, and mass elements) rather than expensive advanced materials or complex active control systems. The design achieves effective vibration absorption through clever mechanical arrangement and parameter optimization of inexpensive components, making the solution economically viable for mass production.

The vibration absorber is designed to function autonomously based on the walking pattern detection, without requiring complex external control systems or expensive actuators. The system self-adjusts its absorption characteristics through mechanical feedback and passive adaptive mechanisms, reducing the need for costly electronic control hardware while maintaining effective vibration suppression.
