A Soft Payload Arm Could Shrink the Stability Margin
Underdamped passive impedance increased oscillation and reduced crawl-gait ZMP margin in simulation.
Summary
Underdamped passive impedance increased oscillation and reduced crawl-gait ZMP margin in simulation.
The quadruped study varied stiffness, damping, gait and payload while using a lightweight passive carrier. Underdamped settings increased joint oscillation and could reduce the zero-moment-point margin during crawl. Trot was treated only as a dynamic excitation case, not compared with crawl on that stability measure.
Why it matters
Underdamped passive impedance increased oscillation and reduced crawl-gait ZMP margin in simulation.
Limits and context
- Trot was treated only as a dynamic excitation case, not compared with crawl on that stability measure.
Key claims
