Abstract

This chapter presents our recent efforts on developing a micro-force sensing mobile microrobot (μFSMM). The design consists of a planar, vision based micro-force sensor end-effector attached to a magnetic microrobot body. The body is made of chemically etched nickel and is driven by an exterior magnetic field. With a known stiffness, the manipulation forces can be determined from observing the deformation of the end-effector through a camera attached to an optical microscope. After analyzing and calibrating the stiffness of a micromachined ...
