Four-wheel, eight-wheel drive mobile robot design

Journal of Physics: Conference Series
Abstract The purpose of this paper is to design and analyze a mechanical system of a four-wheeled eight-wheel drive mobile robot to cope with complex terrain and high-load environments. The walking and steering systems are designed to be independently driven by brushless DC motors for each wheel. The chassis structure is optimized.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

CRISPLD2 Attenuates Intervertebral Disc Degeneration by Suppressing Oxidative Stress‐Induced Ferroptosis through the miR‐548I‐IL17A Axis

Advanced Science, EarlyView.
This study identifies CRISPLD2 as a key protector against IVDD. By regulating ferroptosis through the CRISPLD2–miR‐548I–IL17A axis, CRISPLD2 maintains NPCs homeostasis and reduces oxidative stress. Restoring CRISPLD2 expression effectively alleviates disc degeneration and highlights a promising therapeutic strategy for discogenic low back pain ...
