Positive Solutions of a Hammerstein Integral Equation with a Singular Nonlinear Term, II
Journal of Integral Equations and Applications, 2000 The author presents the existence of a positive measurable solution of a Hammerstein equation of the first kind with a singular nonlinear term at the origin. In section 1 the assumptions and the two theorems obtained are stated. Sections 2, 3 and 4 contain the demonstration and proof of the theorems. Sections 5 and 6 are dedicated to Appendices 1 and 2.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review
Advanced Robotics Research, EarlyView.Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

On A System Of Nonlinear Singular Integral Equations In An Euclidean Space Rn
Demonstratio Mathematica, 1997 The author considers a system of nonlinear singular integral equations in the case when this system may be uncountable. The investigation is based on the topological method and on the general Schauder-Tikhonov theorem. Under some assumptions she gives conditions for the existence of the solution of the considered problem.

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

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,

Efficient and Robust Standing Postures of Quadruped Robots
Advanced Robotics Research, EarlyView.A calibrated static framework estimates load, optimizes torques, and adapts posture so quadruped robots stand efficiently and robustly under external payloads, achieving up to 50% lower torque demand. Inspired by the natural posture adjustments of animals under external loading, this article presents an optimization‐based framework for minimizing joint
