Abstract-- We propose a new method for assembly of 3D
microstructures. Hard magnets are arranged in a novel 120
offset configuration, allowing for in-situ magnetization. The
new configuration makes the use of hard magnets feasible
in batch fabrication, and hard magnets allow for the use of
a uniform external field for application of magnetic torque.
A sequential planner was developed to calculate layout and
magnet orientations for given assemblies, based on this new
magnet configuration. We describe the new magnet configu-
ration, experimentally test the configuration, and present a
planner that generates a planar layout and magnet orientations.
I. INTRODUCTION
3D microstructures have been used in devices such as
microrobots [1],[3],[5], microsensors [6], and micro-optical
devices [12]. As traditional micromachining is not well
suited to fabricating complex 3D structures, self-assembly
