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.

Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing

Advanced Robotics Research, EarlyView.
Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Mechanical behavior and micro-crack propagation mode of fault stick–slip under various roughness conditions

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Characterized by depressions and elevations, the rough surfaces of faults are prone to stress concentration and energy accumulation, leading to localized rupture in the upper and lower blocks. These regions are more susceptible to stick–slip instability,
