Reconfigurable microswarms have received extensive attention recently. In this work, we propose a control strategy for a ribbon-like swarm to perform navigated locomotion with a stable pattern, and perform controllable splitting into double subswarms to reach two targets simultaneously. Two differen…
Remotely actuated small-scale robots have shown promising capabilities in targeted delivery, micromanipulation, and biosensing. However, challenges remain in imaging and control of a robot in a large workspace, especially when conducting targeted navigation in hard-to-reach and tortuous regions of a
After years of development, various swarms of robots have been proposed for many complicated tasks, such as forming patterns, cooperative locomotion, and adapting to different environments. However, controlling microrobotic swarms is still a challenging task owing to the lacking of integrated device…
We propose ultrasound Doppler imaging and magnetic navigation of collective cell microrobots in whole blood. Cell microrobots are cultured using stem cells and iron microparticles, they have spheroidal structures and can be actuated under external magnetic fields. A collective of cell microrobots ca…
In this paper, a novel magnetic manipulation system using mobile coils for remote actuation of magnetic untethered devices in an enlarged workspace is proposed and studied. A parallel mechanism is implemented to actuate the mobile coils. A proof-of-concept prototype is designed and constructed, name…
Dynamic self-assembly is treated as a promising approach for generating a robotic swarm to perform coordinated tasks, and the assembled pattern can be tuned by regulating the energy input. However, location of a dynamically assembled pattern is hard to be determined, especially under global fields,…
