This paper presents a modular approach to motion control using a microconlroller-based stepper motor driver. As an application of the driver, an inexpensive and portable one-dimensional robot was built to automate an existing experimental setup for measurement of adsorption isotherms using the McBain-Bakr technique. Automatic recording of position versus time yields data for the sludy of adsorption/desorption dynamics.
