Image Magnetic Micro Manipulation Platform

Magnetic Micro Manipulation Platform

The Magnetic Micro Manipulation Platform consists of a magnetic field generator and a control system. The magnetic field generator is composed by two orthogonal pairs of Helmholtz coils, which generate a uniform field, and two orthogonal pairs of Maxwell coils, which generate a uniform field gradient. The 2D workspace is 2 mm x 3.5 mm. The maximum magnetic field and gradient are 12 mT and 1.2 T/m, respectively, generated by currents in the range 0-2 A. The control system comprises a laptop, a joypad (SAITEK P580 Blue Rumble Pad), a camera (BASLER scA1390-17gc), a data acquisition board (NI DAQ USB-6259) and custom electronicsA custom electronics is avaiable and it is based on a closed loop op-amp configuration with a Darlington stage. The driving signals for the electronics are generated through the DAQ board by means of a software program developed in LabVIEW (National Instruments, Inc., USA). The magnetic fields and gradients are controlled by the user through the joypad interface. The GUI (graphical user interface) can be adapted in order to full-fill specific testing needs. At the same time, the camera for the 2D visualization of the workspace can be adapted depending on the type of microrobot which is under testing.
