Abstract
A microcomputer-based digitizer was designed, implemented, and tested. The main components of the system include the five-axis articulated mechanical arm, incremental optical encoders, quadrature clock converter-counter circuit, interface card, and the software interface. Incremental optical encoders were tested and decoded to output up and down counts. Kinematic analysis was performed on the instrument in order to arrive to the final position and orientation of the pointer tool. It made use of the Denavit-Hartenberg algorithm to analyze the link-coordinate transformation of the mechanical arm in order to compute for the arm matrix. Errors in the system were attributed to the physical design of the mechanical arm.
