Abstract

This paper discusses recent experiments in the manipulation and assembly of parts with 100 micron outside dimensions and submicron tolerances. The objective of this work is to develop a micromanipulation workcell which can automatically assemble LIGA parts using an assembly plan and a CAD drawing of each of the components. The workcell consists of an AdeptOne robot, precision stages, and long distance microscope, and a high aspect ratio molded polysilicon tweezers for picking up the parts. Fourier optics methods are used to generate synthetic microscope magnifications and depths of field. They also provide reference image features which are used to visually servo the true part to the desired position.
