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,

A Soft Robotic Device for Targeted Massage Therapy of Residual Limbs
Advanced Robotics Research, EarlyView.Residual limb edema after amputation can hinder recovery and delay prosthetic fitting. This study presents a soft‐robotic wearable device that delivers sequential compression through pneumatic McKibben actuators. By replicating the principles of manual lymphatic drainage, the device generates controlled mechanotherapeutic pressure patterns, providing a

Analytical Calculation of Cylindrical Shells in the Form of Second-Order Algebraic Surfaces
Structural Mechanics of Engineering Constructions and BuildingsWhen choosing the shape of a shell, one should strive for the boundary conditions to ensure momentless behavior of the shell. Second-order algebraic surfaces include three degenerate surfaces: parabolic, elliptic, and hyperbolic cylindrical surfaces, and

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation
Advanced Robotics Research, EarlyView.A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

Electronic Journal of Differential Equations, 2019 We study the stability of Riemann solutions to pressureless Euler equations with Coulomb-type friction under the nonlinear approximation of flux functions with one parameter. The approximated system can be seen as the generalized Chaplygin pressure Aw-
