Abstract
This thesis describes the design and construction of an automatic line follower to digitize line data from cartographic charts with a minimum amount of operator participation.
An electromechanical line sensing head is combined with the positive stepping qualities of a digital type servo system and digital control logic to produce a simple and reliable automatic line follower. In the course of the design study, a mathematical model of a stepping motor is developed and verified. This model is then applied to show the effect of varying different circuit parameters on the stepping motor multi-step response. The problem of resonance in the stepping motor is investigated and methods of improving the dynamic performance are derived.
The results from experimental tests on the prototype of the automatic line follower are described. In addition, results are included to demonstrate the performance of the prototype in digitizing a sample chart.
This research was supported by the Canadian Hydrographic Service, Marine Sciences Branch.
