Brief: Bubble microrobots achieve remote speed modulation; study on timing in human-robot collaborative operation; multiple institutions publish a review of efficient NLP methods, and more

A team from the Institute of Mechanics, Chinese Academy of Sciences, published research in Small on magnetically controlled bubble microrobots. By adjusting the orientation of Janus microspheres through a 3D Helmholtz coil magnetic control system, they achieved remote speed modulation, and used microbubble collapse jets to accomplish propulsion, anchoring, and grasping; surface capillary waves can sweep particles in the far field.
