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.

Gravitational core of double field theory
European Physical Journal C: Particles and FieldsDouble Field Theory (DFT) has emerged as a comprehensive framework for gravity, presenting a testable and robust alternative to General Relativity (GR), rooted in the $$\textbf{O}(D,D)$$ O ( D , D ) symmetry principle of string theory.

Advanced Intelligent Systems, EarlyView.Legged robots have advanced in environmental interaction through contact, but most works rely on fixed contact sequences. This work presents a new method based on an indirect optimization method for legged robots to automatically generate contact sequences for complex movements.

A Multimode Soft Robot Based on a Single Braided Tube
Advanced Intelligent Systems, EarlyView.This study introduces a novel soft multimode robot based on a single braided tube directly formed and actuated by SMA wires with distinct initial configurations. By combining contraction, elongation, and bending deformations, the robot achieves straight crawling, turning, inchworm crawling, and rolling without additional actuators.
