Built from parts from two CD-Rom drives mounted perpendicular to each other, this project enabled a pen to move in Cartesian coordinates. Positional feedback was implemented by salvaging parts from computer mice.
Examples of some names written and the results of an auto-calibration.
Inputs are taken from a keypad which would instruct the control circuitry to drive the motors in such a way as to write programmed names with a permanent marker.
Control was implemented on two simultaneously running Pic-micro microcontrollers programmed with C.
The optical encoder wheel is mounted to the motor axle between IR transmitter and detector.
