Tilt mechanism for precision control of down-slope component of gravitational force for micro force generation

Abstract

A simple single-axis tilt mechanism for precision control of the down-slope component of gravitational force is proposed. Precise tilt motion is realized by using a wedge shaped block and a linear actuator driven by a stepping motor. The proposed mechanism can be easily constructed by standardized aluminum frames for the skeletal structure. The measurement result indicates that the tilt angle can be controlled by adjusting the position of the linear actuator and good reproducibility of the tilt angle is achieved by using the proposed tilt mechanism.
