This paper describes a novel 4-axis microgripping system consisting of two fingers, each driven by a 2-axis moving coil actuator taken from a CD-lens assembly. These electromagnetic actuators are small, very linear, virtually frictionless and low cost. We measured the electrical actuator parameters and characterized the actuator performance in terms of displacement vs. current, force vs. current and resonant frequency. Experimental results indicate that the proposed microgripping system can be an attractive solution to the problem of micromanipulating small objects for precision manufacturing and biotechnology with high accuracy in a relatively large workspace
