3. Input will be an ASCII file (.txt) format of 100 bytes max. It is desirable to make use of prefabricated components that can be economically purchased. Important considerations are appearance, size, and cost. The Problem Develop an automated system that plots text on various sizes of poster board.

4. Problem Solution Our design will retro fit a rotary pen turret onto the existing Rover III platform. The Rover III will be programmed to maneuver so that the pen will produce letters on poster board.

6. Marker Functionality #1 Test Markers (Red Sharpe) 1234Average Diameter (inches).449.420.438.449.439 Length (inches) 4.8504.8424.8724.8574.885

7. Reasons For Test #1 Critical marker diameter for marker chuck. Critical marker length for lifter, cam, and rover frame height design.

8. Marker Functionality #2 Test Lifespan Test of Sharpe Estimated life of marker is about 60 minutes of constant ink tip contact.

9. Reasons for Marker Functionality #2 Test See if marker tip changes shape. See how often a marker would have to be changed.
