Collective microrobots enable controlled batch delivery, showing promising application in the biomedical field. However, significant challenges remain in achieving long-distance delivery of collective microrobots in dynamic environments. This study proposes a magnetic actuation strategy for deliveri
Driving decision-making in mixed traffic, characterized by high-dynamic interactions and stochastic behaviors of human-driven vehicles, poses significant challenges for autonomous driving systems. To address these issues, we propose a novel Transformer-based Spatial Temporal Fusion (TSTF) module int
Online path planning for magnetic microrobots actuated by electromagnetic system in dynamic flow field presents significant challenges due to time-varying fluid dynamics, energy constraints, and collision risks. Traditional path planning approaches, which often rely on static flow assumptions or sim
Magnetically actuated nanoparticle microrobots have great potential for biomedical applications, especially in blood vessels. However, they face a complex bifurcation environment, and magnetic control strategies targeting a single pathway limit the operational efficiency of the targeting task. In th
The loaded walking ability of people can be enhanced by lower limb exoskeleton. How to avoid lower limb joint injuries while improving walking efficiency is a major challenge for loaded walking assistance. Inspired by the muscle-skeleton working mechanism of human, we proposed a lower limb exoskelet
Endovascular techniques have been increasingly adapted to medical applications as a minimally-invasive treatment approach to diagnose and treat various vascular diseases. Guidewires are the basic devices in endovascular surgery. The conventional practice of endovascular procedures has a number of dr
Robotic dexterous operation is a long-term challenging problem. Although recent advances in robotic hand have successfully realized some complex operations, its high dexterity and high precision control are still challenges for robotic hands to replace the human hand. Here, this letter developed a t
Various morphologies and motions have been investigated extensively for robots on substrates or interfaces. However, the locomotion of modular robots in 3D free spaces remains challenging owing to zero dependence on boundaries, in particular at small scales. Here we propose simply modularized miniat
Untethered, wirelessly controlled microrobots have a broad application prospect from industrial area, to the bioengineering due to their small scales. In a narrow environment containing viscous resistance and friction fluid, rigid body may damage the micro-objects that the microrobots manipulate. In

Soft swimming microrobots that can be powered and guided remotely by magnetic field show greater potential for numerous applications than traditional rigid counterparts, due to their soft and flexible architectures. However, main challenges in closed-loop control remain to be overcome for the soft r
Magnetically actuated microswimmers have shown great potentials in multiple application scenarios, attracting researchers to investigate their swimming characteristics and controlling methods. However, among those studies, only a small number of closed-loop control schemes have been applied, which i…
Microrobots show great potential to realize a wide range of medical applications especially in a hard-to-reach region within human body. Among a diversity of medical applications, the microrobots are expected to efficiently perform tasks within the human body, but the existing electromagnetic coil s…
We present a general solution for steering microrobotic swarm by dynamic actuating fields. In our approach, the motion of micro-robots is controlled by changing the actuating direction of a field applied to them. The time-series sequence of actuating field's directions can be computed automatically.
Shape descriptor is a concise yet informative representation that provides a 3D object with an identification as a member of some category. This paper developed a concise deep shape descriptor for the first time to address challenging issues from ever-growing 3D datasets in areas as diverse as engin…
Helical microswimmers capable of propulsion at low Reynolds numbers have been proposed for numerous applications. Several different kinds of helical swimmers inspired by E. coli bacteria have been proposed by researchers, and most of them have rigid helical tails. However, high softness could make s…
