MAGNETIC-DRIVEN SWIMMING MICROROBOTS
Proceedings of the 14th International Workshop on Structural Health Monitoring, 2023A magnetic object subject to an external rotating magnetic field would be rotated due to the alignment tendency between its internal magnetization and the field. Based on this principle, 12 shapes of swimming microrobots around 1mm long were designed and 3Dprinted using biodegradable materials Poly (ethylene glycol) diacrylate (PEDGA).

Magnetically-guided in-situ microrobot fabrication
2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2016Mobile microrobots are typically fabricated in a multi-step microfabrication process and then transported into an enclosed workspace for operation. This paper presents a new, 3D printing inspired method for in-situ fabrication of mobile magnetic microrobots with complex topology from a polymer filament on demand directly inside an enclosed operational ...

Magnetic microrobots with addressable shape control
2016 IEEE International Conference on Robotics and Automation (ICRA), 2016Shape shifting soft microrobots are generated from self-folding hydrogel bilayer structures. The folding conditions are analyzed to develop an optimal strategy for producing desired three-dimensional shapes. We present two different methods for programming magnetization in these microrobots that are variant and invariant to folding. The microrobots can

Walking of a magnetically bipedal microrobot
2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011Magnetic microrobots with walking capability are reported. A magnetic object subjected to an externally magnetic field would be attracted and rotated due to the interaction between the field and the induced internal magnetization. Based on this principle, a magnetic microrobot with two legs was designed and fabricated. To remotely power and control the
