This paper presents a technology for remotely navigating a magnetized microrobot in three-degree-of-freedom (3-DOF) using magnetic energy. The magnetic energy source is a magnetic drive unit that consists of six iron-core electromagnets, a soft-iron yoke, and a soft-iron pole-piece. The dynamic models of the magnetically navigated microrobot were derived from the magnetic field model in the wor...

This paper presents a proof-of-concept prototype of a micro force sensing mobile microrobot. The design consists of a planar, elastic mechanism serving as computer vision-based force sensor module, while the microrobot body is made from a magnetic layer driven by a magnetic field. From observing the deformation of the elastic mechanism, manipulation forces can be determined. The deformation is ...

The development of tools for a multi-microrobot manipulating system prototype to handle cells and biomolecules is proposed. The system will be based on a cluster (5 to 10) of small (cm3) mobile autonomous robots, comprising several essential subsystems such as a global positioning system to provide accurate position information of each microrobot and advanced manipulating tools for biological a...

This paper presents a magnetic tumbling microrobot design at the micro-scale. The microrobot has a dumbbell shape whose largest dimension is about 400 μm. When subjected to an exterior predefined magnetic field, the magnetic microagent performs a tumbling motion driven by the interacting magnetic forces and momentums. The magnetic field providing driven force is generated by a coil system consi...

This paper investigates some of the fundamental design issues related to untethered biomedical microrobots guided inside the human body through external magnetic fields. Immediate application areas for these microrobots include cardiovascular, intraocular and inner-ear diagnosis and surgery. Issues investigated include the effects of magnetic actuation forces and viscous drag forces faced by ma...

Intracavity intervention is expected to become more and more popular in the medical practice, both for diagnosis and for surgery. Wireless microrobots are employed in a wide range of biomedical application, they have many potential to accomplish many medical procedures radically, which is due to they can be carried deeply within the body of living organisms to perform tasks safe and reliable. T...

Peritrichously flagellated Escherichia coli swim back and forth by wrapping their flagella together in a helical bundle. However, other monotrichous bacteria cannot swim back and forth with a single flagellum and planar wave propagation. Quantifying this observation, a magnetically driven soft two-tailed microrobot capable of reversing its swimming direction without making a U-turn trajectory o...

Biomimetic underwater microrobots are of great interest for underwater monitoring operations, such as pollution detection and video mapping in restricted underwater environments. Generally speaking, compact structure, multi‐functionality, flexibility and precise positioning are considered incompatible characteristics for underwater microrobots. Nevertheless, we have designed...
