Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Snap and Jump: How Elastic Shells Pop Out
Advanced Robotics Research, EarlyView.Indent an elastomeric shell and let it go. The spherical shells can store and release the elastic energy. Desktop‐scale experiments, material point method simulation, and analytical theory uncover the fundamental mechanism of soft jumping robots.

An Automated Occultation Network for Gravitational Mapping of the Trans-Neptunian Solar System
The Planetary Science JournalWe explore the potential of an array of ${ \mathcal O }(100)$ small fixed telescopes, aligned along a meridian and automated to measure millions of occultations of Gaia stars by minor planets, to constrain gravitational signatures from a “Planet X” mass ...

p‐Cu(OH)2/n‐SrTiO3 Heterojunction for Efficient Photocatalytic Hydrogen Production
Advanced Sustainable Systems, EarlyView.Improving the efficiency of photocatalysts in the hydrogen evolution reaction relies on developing cost‐effective co‐catalysts. This study focuses on p‐Cu(OH)2/n‐SrTiO3 heterojunctions for efficient hydrogen production. 1 wt.% Cu‐based co‐catalyst significantly enhances performance, achieving ≈3.5 times higher hydrogen production compared to pristine ...
