摘要: The MiniMag is a magnetic manipulation system capable of 5 degree-of-freedom (5-DOF) wireless control an untethered microrobot (3-DOF position, 2-DOF pointing orientation). has spherical workspace with intended diameter approximately 10 mm, and completely unrestrained in the rotational degrees-of-freedom. This accomplished through superposition multiple fields, capitalizes on linear representation coupled field contributions softmagnetic- core electromagnets acting concert. prototype consists 8 stationary ferromagnetic cores, producing fields excess 20 mT gradients 2 T/m at frequencies up kHz.
