Manipulation of micrometer to millimeter-scale objects is central to biotechnological and medical applications involving small-scale robotic devices. Mobile untethered microgrippers have been developed, which use magnetic fields for motion and activation of grasping. This letter extends the capabilities of such microgrippers by presenting the first example of reliable and autonomous three-dimensional (3-D) micrograsping and cargo delivery of a microgripper using simple control strategies. This endeavor will allow microgrippers to reliably grasp and transfer microobjects, such as cells, with minimal user input, which is ideal for cooperative tasks performed by multiple microgrippers in future work. The proposed controller autonomously manipulates a 3-D magnetic microgripper for pick-and-place tasks in the 3-D space. By regulating the remotely applied force on the microgripper, the 3-D position and velocity of the …
