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

open access: yesAdvanced 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,

Development and Analysis of the Control Effect of a Reid Damper with Self-Centering Characteristics

open access: yesShock and Vibration, 2018
To improve the recoverability of structures following an earthquake, a Reid friction damper with self-centering characteristics is proposed and its hysteretic behavior is studied by theoretical analysis and experimental research.

Motion-Based Design of Passive Damping Devices to Mitigate Wind-Induced Vibrations in Stay Cables [PDF]

open access: yes, 2018
Wind action can induce large amplitude vibrations in the stay cables of bridges. To reduce the vibration level of these structural elements, different types of passive damping devices are usually installed.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

open access: yesAdvanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Deployment mechanisms on Pioneer Venus probes [PDF]

open access: yes, 1979
Deployment mechanisms were developed to position scientific instruments during probe descent into the Venus atmosphere. Each mechanism includes a provision for pyrotechnic release of the enclosure door, negator springs for positive deployment torque, and

Temperature sensitive controller performance of MR dampers [PDF]

open access: yes, 2009
Magnetorheological (MR) dampers can experience large temperature changes as a result of heating caused by energy dissipation, but control systems are often designed without consideration of this fact.

Enhancement of Calcium Ion Permeation via Resonant Coupling of Ion and Terahertz Waves in Voltage Gated Calcium Channels

open access: yesAdvanced Science, EarlyView.
We introduce a novel, ion‐targeted strategy to enhance calcium permeation in voltage gated calcium channels. By directly driving the ions’ coherent collective motion via resonant coupling with a 1.65 THz field, we lower the inter‐site energy barrier, inducing a statistically significant enhancement of ion influx.
