China tops humanoid-robot patents; US quality remains the benchmark
A LexisNexis patent analysis of over 26,000 patent families shows China dominating humanoid-robot innovation, occupying six of the top ten startups (led by Fourier and AgiBot) and UBTECH singled out for focused patent investment; by end-2025 China held about 73% of morphology-related patents and 63% of portfolio strength. The United States, while smaller in volume, leads in patent quality, with Figure AI, Apptronik and Agility Robotics ranking among the top US contributors and accounting for 11% of global portfolio strength from 5% of morphology-related patents. The report notes rising US-China tech tensions and argues patent data can signal future commercial leadership.

New 3D-printing method lets soft robots bend and grasp on command
Harvard engineers embed motion directly into soft robots with a rotational multimaterial 3D‑printing process that creates hollow pneumatic channels inside flexible filaments. When inflated, these channels cause the structures to bend, twist, or grasp in preprogrammed ways, removing molds and assembly steps and enabling rapid design changes. Demonstrations include a flower-like actuator and a hand-shaped gripper, with potential applications in surgical robotics and delicate-object handling.
Liquid gears promise wear-free robotics, NYU study shows
NYU researchers developed a fluid-based gear system that transmits motion via directed fluid flows instead of interlocking teeth, enabling non-contact transmission and reducing wear and jam risks. Demonstrated with two submerged cylinders in a water–glycerol mix, the approach could inform soft robotics and instantly tunable gear ratios, with findings published in Physical Review Letters.
