A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Science Educators and Researchers Must Uphold the Human Rights of Trans, Nonbinary, and Intersex Persons

open access: yesScience Education, EarlyView.
Abstract Trans, nonbinary, and intersex persons are—and have always been—an integral part of humankind. However, these communities are under attack. We live in a time of growing state repression and the normalization of political violence against trans, nonbinary, and intersex persons throughout much of the world, and we have a responsibility to ...
