Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Large-Scale Testing of a Novel Self-Centering Brace with U-Shaped Plates for Seismic Energy Dissipation

CivilEng
Energy-dissipating braces are novel structural components as they not only accommodate the seismic energy demand but also enhance both the flexibility and overall earthquake resistance of the structure, preventing brittle or non-ductile behavior.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

3. On the Dampimg Force of a Magnetic Damper

, 1947
About ten years ago, Prof. Hagiwara has experimentally shown that the damping force f of a magnetic damper is given by the next expression f=(Cφ^2συD)/S where φ, σ, υ, D and S are total flux, specific conductivity, velocity, thickness of the metallic ...
