Teleoperated Magnetic Endoscopy: A Case Study and Perspective

Advanced Intelligent Systems, EarlyView.
This perspective highlights the recent research efforts in robotic magnetic platforms for telesurgery and their translation to clinical settings for endoscopic procedures. To demonstrate this approach, this work also introduces an in vivo gastroscopy performed in a porcine model, during which an operator in Zurich, Switzerland, successfully controls a ...

Single‐Pump‐Actuated Transformable Dual‐Mode Gripper Based on Bistable and Origami Structures for Cross‐Scale Object Grasping

Advanced Intelligent Systems, EarlyView.
Single‐pump‐actuated transformable dual‐mode gripper (SATDG) that combines vacuum suction and granular jamming to effectively grasp objects ranging from 10 to 300 mm in size, spanning a vast 30‐fold range, with forces from 0.5 to 21 N, is studied. Using a bistable mechanism and origami structure, the SATDG can transform between two modes and activate ...

Modular Stimuli‐Responsive Valves for Pneumatic Soft Robots

Advanced Intelligent Systems, EarlyView.
Modular stimuli‐responsive valves, based on responsive materials (i.e., liquid crystal elastomers and hydrogels) and mechanical mechanisms, can autonomously regulate airflow in the presence of multiple environmental stimuli, such as light and water.
