CFD analysis on hydrodynamic characteristics of ultra-high-pressure water jets: stationary vs. translating nozzle conditions

Engineering Applications of Computational Fluid Mechanics
In the rust removal process via ultra-high-pressure (henceforth UHP) water jet, nozzle translation and rotation significantly affect the jet profile, thereby influencing rust removal performance. Unfortunately, the research on UHP water jets in motion is

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

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.
