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,

Micromechanical Modeling of Rolling Contact Fatigue
, 2021 This thesis investigates the micromechanics of crack initiation and propagation from subsurface inclusions in relation to rolling contact fatigue (RCF) in bearings, using various models with different levels of complexity. First, the problem is examined using a purely elastic model based on Eshelby’s method where it is assumed that crack initiation ...
