Angular Displacement Module Mechanic

Angular Displacement

This lab explores angular displacement measurements using a potentiometer and an incremental encoder. Students will calibrate both sensors for accurately measuring angular displacements, and will examine decoding algorithms for encoders.

Learning Objectives:

After completing this lab, students will be able to:
■ Understand the voltage dividing properties of a potentiometer.
■ Calibrate the output of a potentiometer in terms of angular displacement.
■ Determine an encoder's pulses-per-revolution.
■ Examine non-quadrature, X2, and X4 decoding.
■ Calibrate the output of an encoder in terms of angular displacement.
■ Observe the effect of low sampling on the accuracy of measured data.

Required Skills:

■ Physics I or equivalent.
■ Calculus I or equivalent.
■ Basic LabVIEW Proficiency.
