Magnetic microrobots with addressable shape control

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
Shape 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

Bioinspired soft microrobots actuated by magnetic field

Biomedical Microdevices, 2021
In contrast to traditional large-scale robots, which require complicated mechanical joints and material rigidity, microrobots made of soft materials have exhibited amazing features and great potential for extensive applications, such as minimally invasive surgery.

Walking of a magnetically bipedal microrobot

2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011
Magnetic 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

Development of rolling magnetic microrobots

Journal of Micromechanics and Microengineering, 2010
This 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), 2019
Spermatozoa 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), 2019
This 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, 2012
We 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), 2003
As 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

2013
Remote-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
