Wireless Precise Manipulation of Tumor Spheroids Using a Millirobot Controlled by Permanent Magnetic Traps

Advanced Robotics Research, EarlyView.
A magnetic donut‐like millirobot is developed for label‐free pick‐and‐place of a tumor spheroid wirelessly controlled by a magnetic trap. Spheroids are important 3D multicellular culture systems that recapitulate key structural and functional features of native tissues.

Force–Displacement Characterization of PNIPAM Microactuators

Advanced Robotics Research, EarlyView.
A method to experimentally establish a force–displacement diagram of poly(N‐isopropyl acrylamide) (PNIPAM) microactuators, printed by 2PP, is presented herein. PNIPAM is a hydrogel whose volume and stiffness change with temperature due to the absorption or release of water.

WorMa: An Undulatory Robot With Center of Mass Regulation via Internal Fluid Redistribution for Amphibious Locomotion

Advanced Robotics Research, EarlyView.
WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

A Transnasal Endoscope for Robotically Assisted Gastroscopy

Advanced Robotics Research, EarlyView.
This work introduces a 4.25 mm diameter magnetically navigated transnasal endoscope for upper gastrointestinal (GI) screening and intervention. The system enables precise remote steering throughout the upper GI tract and is demonstrated through in vitro and in vivo experiments, including the robotic execution of preprogrammed retroflexions, trans ...
