“…To date, most of the medical micro/nanorobotic swarms reported result in zero-flow and 2D environments. To yield promising efficacy for clinical use, the capability for swarms to maintain their structural integrity and motion in physiological environments, such as pulsatile biofluid flow and organ motion, must be considered. ,,,, The navigation of micro/nanorobotic swarms in 3D environments must also be taken into considerations (Figure A). ,,, Microrobotic swarms have been shown to be capable of rolling up circular channels [Figure A(i)] and performing adaptive locomotion in 3D environments, such as climbing up stairs and crossing gaps [Figure A(ii)] . However, swarm navigation in a 3D environment without relying on interfaces or solid boundaries requires further research.…”

“…Since the 2000s, controllable microscale (10 –6 m to 10 –3 m) and nanoscale (<10 –6 m) agents, such as helical-shaped microswimmers, , particles, − bacteria, nanowires, , and microactuators, − have been drawing strong attention because of their capability of performing precise delivery and manipulation at the micro/nanoscale. Sophisticated swarming techniques for the micro/nanoagents have also been under intense development, including generation, − pattern reconfiguration, − motion control, , and kinematic models. − More recently, 3D generation − and automated controls − of micro/nanorobotic swarms have been demonstrated. The trend of contemporary micro/nanorobotic swarm research reveals two apparent focuses: (i) to emulate living swarm behaviors to understand natural rules and fundamental mechanisms − and (ii) to develop advanced swarms that enable specific applications, such as therapeutics − and contactless material engineering. − Table summarizes representative milestones in the evolution of robotic swarm technologies.…”

Swarms, which stem from collective behaviors among individual elements, are commonly seen in nature. Since two decades ago, scientists have been attempting to understand the principles of natural swarms and leverage them for creating artificial swarms. To date, the underlying physics; techniques for actuation, navigation, and control; fieldgeneration systems; and a research community are now in place. This Review reviews the fundamental principles and applications of micro/ nanorobotic swarms. The generation mechanisms of the emergent collective behaviors among the micro/nanoagents identified over the past two decades are elucidated. The advantages and drawbacks of different techniques, existing control systems, major challenges, and potential prospects of micro/nanorobotic swarms are discussed.

Magnetic fields are widely utilized for remote control of magnetic objects, with various actuation systems developed for manipulating miniature robots in research and biomedical applications. When designing a manipulation system providing a uniform magnetic field, it is also important to consider both the accessibility of the workspace and the integration of imaging tools. This article presents an electromagnetic coil system that manipulates magnetic objects within a 3D space, enhancing the magnetic field in an upward orientation. The system includes eight metal‐core coils arranged hemispherically to ensure unimpeded access to the workspace and imaging tools, along with two air‐core coils. Easier control and repeatability of the magnetic field are achieved using two joysticks and sequential programming. The versatility of the system is demonstrated by using it to manipulate a magnetic guidewire and to guide micromagnets to various targets. Additionally, using this system, oscillating magnetic fields effectively control swarms of magnetic nanoparticles, enabling operations such as dispersion, assembly, and ribbon‐like shape formation. Furthermore, the manipulation of cell‐based microrobots (cell‐bots) showcases the system's capability to handle single and multiple cell‐bots, facilitating their collection while preserving cell viability. These experiments underscore the system's potential for fundamental biomedical research and various applications.

Blocked fallopian tubes, leading to tubal factor infertility, seriously affect fertility and pregnancy. The current mainstream surgical approach for tubal recanalization is based on conventional catheters and guidewires to clear the blockage. However, it is challenging to treat the distal tubal obstruction due to the large size of the tubal catheter and the poor steerability of the guidewire. Here, we present a magnetically driven robotic microscrew to clear blocked fallopian tubes based on a helical rotating mode. The microscale screw-shaped microrobot is fabricated by 3D microfabrication technology. The motion direction and speed of the microrobot are modulated by customizing the pattern and parameters of the control magnetic field. The microscrew structure generates mechanical force to drill the blockage, and then the destroyed fragments are transported to the tail of the robots via the vortex flow surrounding the microscrew. Finally, we demonstrate the recanalization effect of the proposed microrobot in the fallopian tube-mimicking phantom. The recanalizing microscrew represents a potential strategy for developing autonomous tools to treat the blockage of small lumens.
