Visual outdoor space perception

open access: yesScientific Reports
Visual space perception has been a topic of sustained research since the nineteenth century. Much of this research into the geometry of visual space, however, required observers to make judgments about spatial relationships between isolated points in ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

open access: yesAdvanced 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 ...

Meadows in the Heptgrid and Possible Generalizations [PDF]

open access: yesComputer Science Journal of Moldova
In this paper, we summarize the results about flowers in the heptagrid, the tessellation $(7,3)$ of the hyperbolic plane, results presented for MCU'2024 at Nice, France.

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,

A characterization of hyperbolic spaces

open access: yes, 2006
We show that a geodesic metric space, and in particular the Cayley graph of a finitely generated group, is hyperbolic in the sense of Gromov if and only if intersections of any two metric balls balls is itself "almost" a metric ball.

Universal Gripper for Industrial Manipulation With Enhanced Rigid Mechanics and Self‐Adaptable Fingers

open access: yesAdvanced Robotics Research, EarlyView.
An enhanced universal gripper combining rigid mechanics with self‐adaptable fingers is presented for industrial automation. The novel six‐bar linkage with integrated compliant pad eliminates mechanical interference while enabling passive shape adaptation.

Hyperbolic boundary layer in the vicinity of the shear wave front in shells of revolution [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
Hyperbolic boundary layer equations in thin shells of revolution are constructed in small vicinities of the shear wave fronts (taking into account its geometry) at edge shock loading of the normal type.
