Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Ruled Shells of Conical Type on Elliptical Base
Structural Mechanics of Engineering Constructions and BuildingsThe information about main results on geometry of developable surfaces with an edge of regression which have a directrix ellipse in the base is gathered. These surfaces constitute a group called “Ruled surfaces of conical type on elliptical base”.

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

The triangle construction of ellipse
, 2017 summary:In the first part, we assume well known characteristics of ellipse which are given by triangle construction using main circles. We extend them on some lesser known features like Apollonius's theorem of associated radii of the ellipse.

Advanced Robotics Research, EarlyView.Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

The Spinning Ellipse Speed Illusion
, 2017 The Spinning Ellipse Speed Illusion is an illusion of perceived speed in which a low-aspect ratio “fat” ellipse will appear to rotate more slowly than a higher-aspect ratio “skinny” ellipse that is rotating at the same speed. This illusory percept can be

An Analytically Derived Gauss–Legendre Quadrature for Axis-Aligned Ellipse–Ellipse Intersection
MathematicsAccurate and efficient evaluation of the intersection area between two axis-aligned ellipses is essential in applications where the coordinate system or underlying geometry naturally imposes alignment.

Systematic Exploration of 3D Concrete Printing Parameters for Conformal Printing on Sloped Surfaces
Advanced Robotics Research, EarlyView.A conformal slicing algorithm is developed for robotic 3D concrete printing (3DCP) on sloped surfaces as a first step toward printing slab‐on‐grade foundations on uneven terrain. Systematic experiments quantify the effects of nozzle speed, extrusion rate, and toolpath direction on filament dimension and stability.
