X-Y Plotter
The X-Y plotter is constructed using three T-frames, mounted on a wooden frame. A solenoid is used to lift and lower the pen. Both sides of the long axis have a belt in order accurately track the color dispensing carriage.
User Interface
The user interface includes a joystick that controls the x and y motion of the motor, including speed control. LEDs indicate power and when the pen reaches the end of the track in both directions. A button controls when the pen is lifted.
Professor Schafer Testing the System
The System on Demo Day
Through our efforts, we were able to demonstrate a viable prototype for controlling an X-Y plotter with a bidirectional joystick. We successfully implemented discontinuous motion by using the solenoid, as well as a user interface that gives meaningful feedback to the user.
