About

Magnebotix

MagnebotiX was formed in Q2 2014 and is headquartered in Zurich. Our team of world class researchers and engineers is passionate about the development and production of magnetic manipulation systems, including magnetic field generators and micromagnetic agents. With years of expertise in the field, our products support both fundamental and applied scientific and engineering research. Taking advantage of the transmission of both power and guidance through applied magnetic fields, our systems provide wireless tools to accomplish challenging micromanipulation tasks. They are also used to control untethered mechanical probes in otherwise inaccessible places and for targeted cargo delivery in minimally invasive biological studies.

Activities

Magnebotix produces and markets the MFG-100 & MFG-100-i (reference 1) magnetic field generating systems developed in the Institute of Robotics and Intelligent Systems at the ETH Zürich, Switzerland. The MFG system is capable of generating a wide variety of static or varying magnetic fields. With our system, users carry out research on magnetic field-dependent phenomena and develop applications for magnetic microrobots. The versatile MFG-100 & MFG-100-i can produce fields to activate modes as diverse as field gradient response, stick-slip or rolling motions, and flagellar swimming. Various applications are presented in references 2- 4.

Magnebotix also produces the RodBot (reference 5), another development of the Institute of Robotics and Intelligent Systems. The RodBot is a wireless, mobile, rod-shaped microrobot that is guided and powered by an externally applied magnetic field. Through its rolling motion in a low Reynolds number environment, a RodBot generates fluid flow with a rising component ahead and a travelling vortex above itself. Using this flow pattern RodBots can select a desired micro-object and transport it to a target location using gentle fluid flow as the sole motive force. RodBots are thus ideally suited for the manipulation of small, delicate objects in solution. An application for the harvesting of delicate protein crystals is detailed in reference 6.
