Electromagnetic Steering of a Magnetic Cylindrical Microrobot Using Optical Feedback Closed-Loop Control [PDF]
International Journal of Optomechatronics, 2014 Control of small magnetic machines in viscous fluids may enable new medical applications of microrobots. Small-scale viscous environments lead to low Reynolds numbers, and although the flow is linear and steady, the magnetic actuation introduces a ...

Development of rolling magnetic microrobots
Journal of Micromechanics and Microengineering, 2010This paper reports magnetic microrobots with rolling capability. A magnetic object subjected to an externally rotating magnetic field would be rotated due to the tendency of alignment between its internal magnetization and the field. Based on this principle, a magnetic microrobot in a spherical body with a diameter of several hundred microns was ...

Sperm-templated magnetic microrobots
2019 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS), 2019Spermatozoa are efficient microswimmers which perform a bending wave motion for their forward propulsion. By binding positively charged iron oxide microparticles to the surface of negatively charged bull spermatozoa, we fabricate sperm-templated biohybrid magnetic microrobots.

Permanent Magnets based Actuator for Microrobots Navigation
2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019This paper presents a novel design of four permanent magnet based actuator for magnetic drug targeting of therapeutic microrobots. Drugs are transported through therapeutic magnetic boluses composed of magnetic particles controlled by magnetic gradients. In this study, to maximize the effect of the treatment and minimize adverse effects on the patient,

Polymer-based Wireless Resonant Magnetic microrobots
2012 IEEE International Conference on Robotics and Automation, 2012We present a class of Wireless Resonant Magnetic Microactuator (WRMMA) that integrates a polymer spring/body structure with electroplated ferromagnetic masses. The new devices, which we call PolyMites as they are derived from our previous MagMites, are simpler, faster and cheaper to fabricate than the MagMite.

Magnetic rotational micro-wings applicable to microrobots
Proceedings 1999 IEEE/RSJ International Conference on Intelligent Robots and Systems. Human and Environment Friendly Robots with High Intelligence and Emotional Quotients (Cat. No.99CH36289), 2003As the method of mobility for microrobots flight is more advantageous than walking due to the scale effect. In this work the flight mechanism that gains thrust by rotating magnetic wings in an alternating magnetic field is proposed. Micro-sized models whose wings are around 1 mm long were fabricated using MEMS technology.

Bacteria-Inspired Magnetic Polymer Composite Microrobots
2013Remote-controlled swimming microrobots are promising tools for future biomedical applications. Magnetically actuated helical microrobots that mimic the propulsion mechanism of E. coli bacteria are one example, and presented here is a novel method to fabricate such microrobots. They consist of a polymer-nanoparticle composite, which is patterned using a
