Crater Observing Bioinspired Rolling Articulator (COBRA)
Advanced Intelligent Systems, EarlyView.Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review
Advanced Intelligent Systems, EarlyView.This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

The billiard in a regular polygon
Geometric and Functional Analysis, 1992 Let \(P_ n\) be a regular \(n\)-gon. From the Ikehara Tauberian theorem one infers that there exists \(c_ n > 0\) such that the growth function of the length spectrum of the billiard in \(P_ n\) satisfies the asymptotic formula: \[ N(P_ n,t)\sim c_ n{t^ 2\over\| P_ n\|}\qquad (t\to \infty)\quad (\| P\|=\text{area}(P_ n)).\tag{1} \] The values \(c_ 3 ...

Study on the Fragmentation Characteristics and Dust Generation Mechanism of Coal Cutting by Pick
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT During underground excavation, coal dust generation threatens miners' health and damages ecosystems. Its generation is directly influenced by cutting pick performance and inherent coal properties. This study investigates the effects of coal properties and cutting parameters on coal fragmentation characteristics from a mesoscopic perspective ...
