OctoMag

IMG_9080.JPG

Like the MFG-100, the MagnebotiX OctoMag magnetic field generator offers five-degree-of-freedom (5-DOF) wireless magnetic control (3-DOF position and 2-DOF pointing orientation) but in a larger working volume. Forces and torques can be applied independently on magnetic materials on the µm- to mm scale. Closed-loop control of the microobjects can be handled in 3D by a simple proportional-derivative controller which tracks the position in the working volume using a dual camera system. The OctoMag is delivered with an outer frame that provides easy positioning in the lab. The inner, self-contained generator unit can be inclined at 0 (shown), 30 or 45 degrees to facilitate experimental access to the magnetic workspace, or can be removed from the frame and incorporated into an experimental setup in the laboratory
