About this Research Topic
In recent years, small-scale untethered robots ranging from nanometer-scale to millimeter-scale have shown their great potential in microrobotic targeted delivery. Toward this objective, various actuation and locomotion modalities have been designed for untethered microrobots that are remotely actuated by magnetic fields, ultrasonic fields, light, chemical fuels, etc. In addition to these advances, how to navigate microrobots in vivo (e.g. human body) is still a challenging issue.
In recent studies, most of the control and feedback approaches rely on optical microscopy, which is not feasible for in vivo localization and tracking. In addition, the working scenarios of microrobots are still much simpler compared to real in-vivo environments. This Research Topic highlights the recent advances in imaging-guided navigation methods that enable the intelligent microrobotic targeted delivery in complex environments, especially the ex-vivo and in-vivo environments.
Navigation of untethered microrobots with in vivo imaging modalities is vital for microrobotic targeted delivery in the human body, which is a challenging yet untackled problem. To pave the way for this goal, the objective of this Research Topic is to present relevant advanced methods to address the imaging-guided microrobot navigation in complex environments, including microrobot imaging modalities, theoretical and experimental results in complex environment, and microrobot planning and control techniques. We hope this Research Topic would serve as an open platform to collect papers that could attract attention from researchers in related research fields, and this paper collection can become a valuable forum for researchers in this topic.
